Type Ia supernova progenitors are white dwarf stars that are close to the Chandrasekhar limit of about 1.44 solar masses and are accreting matter from a binary companion star. The list includes massive Wolf–Rayet stars , which may become Type Ib/Ic supernovae , particularly oxygen-sequence (Wolf-Rayet WO) stars.
However, the first dredge-up occurs soon after a star reaches the red supergiant phase and so this only means that Betelgeuse has been a red supergiant for at least a few thousand years. The best prediction is that Betelgeuse has already spent around 40,000 years as a red supergiant, [18] having left the main sequence perhaps one million years ago.
In the video below, take a look at the strange happenings on Betelgeuse with Dr. Andrea Dupree from the Center for Astrophysics. (Video credit: The Cosmic Companion) “It’s still a really big ...
Models indicate that even rapidly rotating main-sequence stars should be braked by their mass loss so that red supergiants hardly rotate at all. Those red supergiants such as Betelgeuse that do have modest rates of rotation may have acquired it after reaching the red supergiant stage, perhaps through binary interaction. The cores of red ...
English: Comparison of size of Betelgeuse (largest dull-red sphere inside Jupiter's orbit) and R Doradus (red sphere shown inside Earth's orbit) together with the orbits of Mars, Venus and Mercury and the stars Rigel and Aldebaran from Image:1e10m comparison Rigel, Aldebaran, and smaller - antialiased no transparency.png, to scale.
Betelgeuse's precise nature differs according to the medium he appears in. He has been depicted as a ghost, a demon and a supernatural monster, with motivations ranging from a love of chaos to a desire for human companionship. Each entry in the series involves Betelgeuse's interactions with Lydia Deetz, a goth fascinated with the "strange and ...
Already Gone is a 2019 American thriller drama film written and directed by Christopher Kenneally and starring Tyler Dean Flores, Justine Skye, Seann William Scott and Shiloh Fernandez. It is Kenneally's feature narrative directorial debut. [1] Keanu Reeves served as an executive producer of the film. [2]
E0102, short for 1E 0102.2-7219, is the remnant of a supernova that exploded in the Small Magellanic Cloud, a neighbouring galaxy of the Milky Way. [1] The supernova was caused when a star much more massive than the Sun collapsed under its own gravity. The explosion would have been visible from the Southern Hemisphere of the Earth over 1000 ...
