The Worlds of Aldebaran (French: Les Mondes d'Aldébaran) is a French science-fiction comic series written and illustrated by Léo and published by Dargaud in French and Cinebook in English. The Aldebaran saga is divided into 7 cycles: Aldebaran and its sequels Betelgeuse, Antares, Survivors, Return to Aldebaran, Neptune and Bellatrix.
Betelgeuse, α Ori, 58 Ori, HR 2061, BD +7°1055, HD 39801, FK5 224, HIP 27989, SAO 113271, GC 7451, CCDM J05552+0724, AAVSO 0549+07. Database references. SIMBAD. data. Betelgeuse is a red supergiant star in the constellation of Orion. It is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in its ...
Antares is the brightest star in the constellation of Scorpius. It has the Bayer designation α Scorpii, which is Latinised to Alpha Scorpii. Often referred to as "the heart of the scorpion", Antares is flanked by σ Scorpii and τ Scorpii near the center of the constellation. Distinctly reddish when viewed with the naked eye, Antares is a slow ...
For example, Betelgeuse has the K-band apparent magnitude of −4.05. [5] Some stars, like Betelgeuse and Antares, are variable stars, changing their magnitude over days, months or years. In the table, the range of variation is indicated with the symbol "var". Single magnitude values quoted for variable stars come from a variety of sources.
Orange to red stars with complex band spectra, such as Betelgeuse and Antares. This corresponds to the modern class M. Secchi class IV: In 1868, he discovered carbon stars, which he put into a distinct group: [47] Red stars with significant carbon bands and lines, corresponding to modern classes C and S. Secchi class V
Rigel is an intrinsic variable star with an apparent magnitude ranging from 0.05 to 0.18. [5] It is typically the seventh-brightest star in the celestial sphere, excluding the Sun, although occasionally fainter than Betelgeuse. [31] Rigel appears slightly blue-white and has a B-V color index of −0.06. [32]
Red supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) and a stellar classification K or M. [1] They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares A are the brightest and best known red supergiants (RSGs), indeed the only first ...
Aldebaran < Rigel < Antares < Betelgeuse 6. Betelgeuse < Mu Cephei < VV Cephei A < VY Canis Majoris. A very large and luminous star, VY CMa is among the most extreme stars in the Milky Way and has an effective temperature below 4,000 K (3,730 °C; 6,740 °F). It occupies the upper-right hand corner of the HR diagram although its exact ...
