Bulletin of the American Astronomical Society (BAAS; Bull. Am. Astron. Soc.) is the journal of record for the American Astronomical Society established in 1969. It publishes meetings of the society, obituaries of its members, and scholarly articles. Four issues are published per year that are collected into a single volume.
Articles are indexed, and often archived, from the Astrophysics Data System, using the journal code BAAS.

18 Scorpii is a solitary star located at a distance of some 45.3 light-years (13.9 parsecs) from Earth at the northern edge of the Scorpius constellation. It has an apparent visual magnitude of 5.5, which is bright enough to be seen with the naked eye outside of urban areas.
18 Scorpii has some physical properties in common with the Sun, a G-type star. Cayrel de Strobel (1996) included it in her review of the stars most similar to the Sun, and Porto de Mello & da Silva (1997) identified it as a younger solar twin. Some scientists therefore believe the prospects for life in its vicinity are good. However, no planet has yet been discovered orbiting this star.AXP 1E 1048-59
Anomalous X-ray pulsar (AXP) 1E 1048.1-5937 was the first AXP ever observed to emit an SGR-like X-ray burst. It is also the closest magnetar to Earth.American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe.Apache Point Observatory
The Apache Point Observatory (APO; obs. code: 705) is an astronomical observatory located in the Sacramento Mountains in Sunspot, New Mexico, United States, approximately 18 miles (29 km) south of Cloudcroft. The observatory is operated by New Mexico State University (NMSU) and owned by the Astrophysical Research Consortium (ARC). Access to the telescopes and buildings is private and restricted During the 2018 closure of Sunspot, Apache Point Observatory remained open, although court documents later showed that the accused was employed at Apache Point Observatory.BAAS

CX CMa (CX Canis Majoris) is a blue variable star in the Canis Major constellation. Discovery of this variable is usually credited to German Astronomer Cuno Hoffmeister in 1931, although this remains uncertain.It is an eclipsing binary of β Lyr type (semi-detached) whose magnitude varies between 9.9 and 10.6 with a period of 0.95462500 day (22.911000 hour). The variability was first discovered in 1931. Doubts arose because of scatter in the data and the small amplitude, but the discovery was confirmed by 1949. Its Algol-type light curve exhibits the O'Connell effect, meaning that there is a magnitude difference between subsequent maxima.The temperature of the secondary star has been estimated at about 10,600 K and its mass at 3.4 M☉. The spectral type of the secondary star is estimated to be in the B8 to A0 range.Galactic tide
A galactic tide is a tidal force experienced by objects subject to the gravitational field of a galaxy such as the Milky Way. Particular areas of interest concerning galactic tides include galactic collisions, the disruption of dwarf or satellite galaxies, and the Milky Way's tidal effect on the Oort cloud of the Solar System.HD 59686
HD 59686 is a 5th magnitude star approximately 316 light years away in the constellation Gemini.NGC 1399
NGC 1399 is a large elliptical galaxy in the Southern constellation Fornax, the central galaxy in the Fornax cluster.NGC 7727
NGC 7727 is a peculiar galaxy in the constellation Aquarius.Naiad (moon)
Naiad ( NAY-əd or NY-əd; Greek: Ναϊάδ-ες), also known as Neptune III, is the innermost satellite of Neptune, named after the Naiads of Greek legend.P-type asteroid
P-type asteroids have low albedo and a featureless reddish spectrum. It has been suggested that they have a composition of organic rich silicates, carbon and anhydrous silicates, possibly with water ice in their interior. P-type asteroids are found in the outer asteroid belt and beyond. There are 33 known P-type asteroids.Purple Earth hypothesis
The Purple Earth hypothesis is an astrobiological hypothesis that life forms of early Earth were retinal-based rather than chlorophyll-based, making Earth appear purple rather than green. An example of a retinal-based organism today is the photosynthetic microbe collectively called halobacteria.The difficulty with this hypothesis is that retinal-based photosynthesis requires either arginine or oxygen in the environment. As a complex amino acid, arginine is not likely to have been available in the levels needed. Oxygen only became available in earth's environment after the development of chlorophyll-based photosynthesis, and given that retinal organisms also require oxygen to synthesize critical substances for life, the possibility that retinal life-forms could have preceded chlorophyll-based ones as the most common photosynthetic organisms is unlikely.Red Buttes Observatory
Red Buttes Observatory (RBO) is an astronomical observatory owned and operated by University of Wyoming. It is located 15 kilometers (9 mi) south of Laramie, Wyoming (USA) and was founded in 1994. The observatory houses a 0.6 m (24 in) telescope built by DFM Engineering. There are two instruments available: a 1024x1024 imaging camera, and a near-infrared camera. A second, smaller telescope built by Orion is mounted on the main telescope. Recent research includes monitoring Cepheid variable stars and follow-up observation of gamma-ray bursts.Research Consortium On Nearby Stars
The REsearch Consortium On Nearby Stars (RECONS) is an international group of astronomers founded in 1994 to investigate the stars nearest to the Solar System - with a focus on those within 10 parsecs (32.6 light years), but as of 2012 stretching the horizon to 25 parsecs. In part the project hopes a more accurate survey of local star systems will give a better picture of the star systems in the Galaxy as a whole.Robert J. Nemiroff
Dr. Robert J. Nemiroff is a Professor of Physics at Michigan Technological University. He received his Ph.D. from the University of Pennsylvania in Astronomy and Astrophysics in 1987 and his B.S. from Lehigh University in Engineering Physics in 1982. He is an active researcher with interests that include gamma-ray bursts, gravitational lensing, and cosmology, and is the cofounder and coeditor of Astronomy Picture of the Day (APOD), the home page of which receives over a million hits a day, approximately 20% of nasa.gov traffic. He is married and has one daughter.Splatalogue
Splatalogue is a database for astronomical spectroscopy which contains information on nearly six million spectral lines and is maintained by the National Radio Astronomy Observatory (NRAO). The name is a portmanteau of "spectral line catalogue".
It contains data from seven catalogues and other sources of spectral line data and is accessible via an online search interface.Tortugas Mountain Observatory
Tortugas Mountain Observatory (TMO) is an astronomical observatory owned and operated by New Mexico State University (NMSU). It is located on Tortugas Mountain, also known locally as 'A' Mountain, in southern New Mexico (USA), approximately 8 kilometers (5.0 mi) southeast of Las Cruces and 4 kilometers (2.5 mi) east of the NMSU campus. Founded in 1963 under the supervision of Clyde Tombaugh, the observatory focused on observing the planets. Much of the information captured at TMO is now available through the Planetary Data System's Atmospheres Node, which is managed by NMSU. The two-dome observatory building was completed in 1964, though observing began with one of the telescopes in 1963. A second building, with a larger single dome, was completed at the opposite end of the ridgeline of Tortugas Mountain in 1967. Regular use of TMO ceased in 1999 or 2000, but the observatory equipment was not dismantled. In 2008 it was used for the Lunar CRater Observing and Sensing Satellite project. In 2010, efforts to revive the observatory for use by the American Association of Variable Star Observers began. As of 10 June 2011, work on project was reported to be 60-75% done.Wyoming Infrared Observatory
The Wyoming Infrared Observatory (WIRO) is an astronomical observatory owned and operated by the University of Wyoming. It is located 40 kilometers (25 mi) southwest of Laramie, Wyoming (USA) on Jelm Mountain. It was founded in 1975, and observations began at the site in 1977. Recent research performed at WIRO includes searching for runaway stars, monitoring short-term variations in blazars, and monitoring massive binary stars.
