Very low. Such a companion would have been detected by now, even if only through its gravitational effects.

What is the 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.

What is the size of alcor star?

Alcor is a binary star system located in the Big Dipper constellation. The primary star, Alcor A, is a main sequence star with a mass about 1.9 times that of the Sun and a radius around 1.75 times that of the Sun. The companion star, Alcor B, is a smaller red dwarf star.


Why does the companion star wrap around the nuetron star?

The companion star can become gravitationally bound to the neutron star due to their close proximity and strong gravitational interactions. The intense gravity of the neutron star can cause the companion star's outer layers to be stripped away, forming an accretion disk around the neutron star. This process can eventually lead to the companion star's material being accreted onto the neutron star.


What is the closest star from Earth?

The Sun, which is a fairly ordinary star, is the closest star to Earth. I presume that's not what you meant. The next closest is Proxima Centauri, a dwarf star 4.2 light years from our system, and its much brighter companion Alpha Centauri is next closest.
