What is an example of a red supergiant star?
Red Supergiants The much brighter, but still reddened star is called a red supergiant. Betelgeuse, at the shoulder of Orion, is the best-known example.
What are super red giants?
A red supergiant is an aging giant star that has consumed its core’s supply of hydrogen fuel. Helium has accumulated in the core, and hydrogen is now undergoing nuclear fusion in the outer shells. These shells then expand, and the now cooler star takes on a red color. They are the largest known stars.
What are red giants called?
Red Giant (RG) stars result from low- and intermediate-mass Main Sequence stars of around 0.5-5 solar masses. Examples of well-known stars in the RG phase are Aldebaran (Alpha Tauri) and Mira (Omicron Ceti). More massive Main Sequence stars evolve more quickly and expand further to become Red Super Giants (RSG).
What is the biggest red giant star?
VY Canis Majoris
The largest known red supergiant is thought to be VY Canis Majoris, measuring about 1800 times the size of the Sun.
What is a red supergiant?
red supergiant. An extremely large red giant star with a minimum of 15 solar masses. The best known red supergiant is Betelgeuse, with a luminosity about 10,000 times that of the Sun. When a supergiant collapses into a supernova, it may result in either a neutron star or a black hole.
Are red super giant stars luminous?
Red supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares are the brightest and best known red supergiants (RSGs), indeed the only first magnitude red supergiant stars
Is the Sun a red supergiant?
People always want to know if the Sun will become a red supergiant. For stars about the size of the Sun (or smaller), the answer is no. They do go through a red giant phase, though, and it looks pretty familiar. When they begin to run out of hydrogen fuel their cores begin to collapse.
What is a red giant supernova?
Both supernovas and red giants are names for a stage in a star’s life – the stage when a star is dying. Very large stars (8-10x the size of the Sun) will explode into a supernova when they die. The explosion is so large that the light from the star will outshine all other stars in the galaxy.
