Stars often come in groups of two or more. In the case of a binary star (two stars), the two stars move around their common center of mass - one complete orbit every few hours, days, years, or even thousands of years - just like the planets orbit the Sun. Each of these stars would be the "companion" of the other one. One of these stars can become a black hole; in that case, the gravitational situation doesn't really change - the two (the black hole and the star, in this case) will continue orbiting their common center of mass.

What do you call two companion stars?
Two companion stars are referred to as a binary star system.
What type of star is sadatoni?
Sadatoni, also known as Zeta Aurigae, is a binary star . So, one star is a bright giant or a supergiant. It's companion is a main-sequence star.
Is arcturus a double star?
Arcturus is not a double star; it is classified as a single giant star, specifically a red giant of spectral type K1. However, it does have a very faint companion that is often not considered in the context of double stars due to its low brightness. This companion is not a part of Arcturus's primary system but is instead a background star. Therefore, Arcturus is primarily known as a solitary star.
Is sirus an asteroid?
No, Sirius is not an asteroid. Sirius is a binary star system consisting of the brighter star, Sirius A, and its companion, Sirius B, which is a white dwarf star. It is the brightest star in the Earth's night sky.
What can a white dwarf do to it's companion star?
Depending on the distance between the binary pair, it is possible for the white dwarf to draw gas from it's companion causing the star to reach the Chandrasekhar limit causing the white dwarf to explode as a nova or a type La supernova.
Explosion of companion star of the sun?
Nothing is known about any companion star. There is a "Nemesis hypothesis", according to which there could be one, but no companion has been confirmed.
If the sun had a companion star what probably became of it?
It is possible that the Sun had a companion star, and that the two became separated due to interactions of other nearby stars.
What happens to a star when it becomes a giant if it has a close binary companion?
Matter can be transferred from the giant to the companion
Does the star polaris make a revolution around the sun?
No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".No. Nor does any other star, unless there is an unknown companion to our Sun, like the hypothetical "Nemesis".

Who invented the companion star theory?
Fred Hoyle
What is binary star hypothesis?
This hypothesis was proposed by Lyttleon in 1938. Before the formation of planets, the sun had a companion star. Another star approached close to these double stars and dragged the companion star away. A gaseous filament was torn from the companion star and it remained close to the sun.The planets were originated from this gaseous filament in the same way as described in the gaseous tidal hypothesis.

How do you color your companion on Star Wars the old republic?
You cannot literally "color" your companion in SWTOR (star wars the old republic), but you can get customizations which are things that you equip on your companion and their physical appearance can be changed, which includes color. If your customization looks ugly, you unequip it on the companion thing on your character sheet. The companion customizations only change physical apperance and do NOT change the stats.
Why does the companion star wrap around the nuetron star?
The extreme gravitational field of the neutron star...an object with typically 4 to 8 times the mass of our sun, packed into a diameter of about eight miles...pulls mass off of any close companion star, which spirals into the neutron star. If the companion star is close enough, it may over time totally disintegrate and be consumed by the neutron star, which itself may become massive enough to finally become a stellar "black hole", an object whose surface escape velocity would be greater than the speed of light, so that nothing, not even light, can escape beyond its "event horizon".
What is an explosion seen when a white dwarf captures H from a companion star?
When a white dwarf star accretes hydrogen from a companion star, it can trigger a runaway nuclear fusion reaction that causes a sudden and bright increase in brightness called a nova. This explosion is not as powerful as a supernova, and the white dwarf usually survives to potentially experience multiple nova events.
What is the probability that our sun has a companion star?
Very low. Such a companion would have been detected by now, even if only through its gravitational effects.
