Double layer (plasma physics)

A double layer is a structure in a plasma consisting of two parallel layers of opposite electrical charge. The sheets of charge, which are not necessarily planar, produce localised excursions of electric potential, resulting in a relatively strong electric field between the layers and weaker but more extensive compensating fields outside, which restore the global potential. Ions and electrons within the double layer are accelerated, decelerated, or deflected by the electric field, depending on their direction of motion.

Double layers can be created in discharge tubes, where sustained energy is provided within the layer for electron acceleration by an external power source. Double layers are claimed to have been observed in the aurora and are invoked in astrophysical applications. Similarly, a double layer in the auroral region requires some external driver to produce electron acceleration.

Electrostatic double layers are especially common in current-carrying plasmas, and are very thin (typically ten Debye lengths), compared to the sizes of the plasmas that contain them. Other names for a double layer are electrostatic double layer, electric double layer, plasma double layers. The term ‘electrostatic shock’ in the magnetosphere has been applied to electric fields oriented at an oblique angle to the magnetic field in such a way that the perpendicular electric field is much stronger than the parallel electric field, In laser physics, a double layer is sometimes called an ambipolar electric field.Double layers are conceptually related to the concept of a 'sheath' (see Debye sheath). An early review of double layers from laboratory experiment and simulations is provided by Torvén.

Eastern Anatolia Observatory

Eastern Anatolia Observatory (Turkish: Doğu Anadolu Gözlemevi, shortly DAG) is proposed ground-based astronomical observatory of Atatürk University in Erzurum, Turkey.The project to establish an observatory in Erzurum is conducted by the Astrophysics Research and Application Center of Atatürk University with the scientific and technical coordination of TÜBİTAK National Observatory and financial support of the Ministry of Development, Government of Erzurum Province, 40 universities and seven observatories in the region. It is the country's biggest project for astronomy, astrophysics and space science.The observatory will be built on a land of 2,500 decares (2.5 km2; 0.97 sq mi) atop Karakaya Hill at 3,170 m (10,400 ft) above sea level within the Konaklı Ski Resort 25 km (16 mi) south of Erzurum. It will host Turkey's first infrared telescope. The telescope will have an active primary mirror of 4 m (13 ft) in diameter and will be equipped with adaptive optics (AO) technology. The contract for the construction of the telescope has been awarded to the Belgian company AMOS in 2014. The request for tender for the design and construction of the rotating hemispherical dome to house the large telescope

was won by the Italian company EIE Group Srl in November 2015. The completion of the observatory is scheduled for end 2019.

Emilio Santos Corchero

Emilio Santos Corchero, born 7 October 1935 (San Vicente de Alcantara, Extremadura, Spain), is a theoretical physicist, professor at the Universities of Costa Rica (1964–68), Valladolid (1968-76) and Cantabria (Spain) (1976-). In the year 1998 he received the Medal of the Spanish Society of Physics.

His scientific work (about 100 articles in scientific journals) has been mainly devoted to develop a stochastic interpretation of quantum mechanics that maintains strict causality (i. e. supporting Einstein’s opinion that "God does not play dice"). In that interpretation the dispersion of results in the measurements is due to lack of control of all relevant factors rather than to a lack of causality (as many quantum physicists believe). For a summary see Foundations of Science, 20, 357-386 (2015). An application has been the study of "parametric down conversion" experiments using the Wigner representation of quantum optics; see European Physical Journal D 13, 109-119 (2001) (in collaboration with A. Casado, T. W. Marshall and R. Risco-Delgado) and references therein. A related subject of interest has been the meaning of the Bell inequalities and the requirements for their empirical tests to be reliable. See Physics Letters 98A, 5-9 (1983) (in collaboration with F. Selleri and T. W. Marshall), Physics Letters 115A, 363-365 (1986), Physical Review A 46, 3646-3656 (1992), International Journal of Theoretical Physics 42, 2545-2555 (2003). The stochastic interpretation rests upon the assumption that the quantum vacuum consists of real fields. Their fluctuations might explain the "dark energy" recently discovered in cosmology; see Astrophysics and Space Science, 332, 423-435 (2011). Another subject of interest has been the study of relativistic stars in order to see whether some modifications of general relativity (possibly of quantum origin) might prevent the collapse to singularities ("black holes"); see Astrophysics and Space Science 341, 411-416 (2012).

Gravitational interaction of antimatter

The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. While the consensus among physicists is that gravity will attract both matter and antimatter at the same rate that matter attracts matter, there is a strong desire to confirm this experimentally.

Antimatter's rarity and tendency to annihilate when brought into contact with matter makes its study a technically demanding task. Furthermore, gravity is much weaker than the other fundamental forces, for reasons still of interest to physicists, complicating efforts to study gravity in systems small enough to be feasibly created in lab, including antimatter systems.

Most methods for the creation of antimatter (specifically antihydrogen) result in high-energy particles and atoms of high kinetic energy, which are unsuitable for gravity-related study. In recent years, first ALPHA and then ATRAP have trapped antihydrogen atoms at CERN; in 2012 ALPHA used such atoms to set the first free-fall loose bounds on the gravitational interaction of antimatter with matter, measured to within ±7500% of ordinary gravity, not enough for a clear scientific statement about the sign of gravity acting on antimatter. Future experiments need to be performed with higher precision, either with beams of antihydrogen (AEGIS) or with trapped antihydrogen (ALPHA or GBAR).

In addition to uncertainty regarding whether antimatter is gravitationally attracted or repulsed from other matter, it is also unknown whether the magnitude of the gravitational force is the same. Difficulties in creating quantum gravity theories have led to the idea that antimatter may react with a slightly different magnitude.

Plasma cosmology

Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe beyond the Solar System. In contrast, the current observations and models of cosmologists and astrophysicists explain the formation, development, and evolution of astronomical bodies and large-scale structures in the universe as influenced by gravity (including its formulation in Einstein's theory of general relativity) and baryonic physics.Some theoretical concepts about plasma cosmology originated with Hannes Alfvén, who tentatively proposed the use of plasma scaling to extrapolate the results of laboratory experiments and plasma physics observations and scale them over many orders-of-magnitude up to the largest observable objects in the universe (see box.)

Cosmologists and astrophysicists who have evaluated plasma cosmology reject it because it does not match the observations of astrophysical phenomena as well as current cosmological theory. Very few papers supporting plasma cosmology have appeared in the literature since the mid-1990s.

The term plasma universe is sometimes used as a synonym for plasma cosmology, as an alternative description of the plasma in the universe.

Stellar pulsation

Stellar pulsations are caused by expansions and contractions in the outer layers as a star seeks to maintain equilibrium. These fluctuations in stellar radius cause corresponding changes in the luminosity of the star. Astronomers are able to deduce this mechanism by measuring the spectrum and observing the Doppler effect. Many intrinsic variable stars that pulsate with large amplitudes, such as the classical Cepheids, RR Lyrae stars and large-amplitude Delta Scuti stars show regular light curves.

This regular behavior is in contrast with the variability of stars that lie parallel to and to the high-luminosity/low-temperature side of the classical variable stars in the Hertzsprung-Russell diagram. These giant stars are observed to undergo pulsations ranging from weak irregularity, when one can still define an average cycling time or period, (as in most RV Tauri and semiregular variables) to the near absence of repetitiveness in the irregular variables. The W Virginis variables are at the interface; the short period ones are regular and the longer period ones show first relatively regular alternations in the pulsations

cycles, followed by the onset of mild irregularity as in the RV Tauri stars into which they gradually morph as their periods get longer. Stellar evolution and pulsation theories suggest that these irregular stars have a much higher luminosity to mass (L/M) ratios.

Many stars are non-radial pulsators, which have smaller fluctuations in brightness than those of regular variables used as standard candles.
