Solar Mass

In Astrophysical, the solar mass is the unit of Masse conventionally used for the star S or the others object S massive. It is equal to the mass of the Sun.

Its symbol and its value are:

M_ {\ odot} = 1,9891 \ times 10^ {30} \; {\ rm kg} .

The solar mass is worth approximately 330  000 times mass of the Ground. The stars having the smallest mass are the dwarf reds, smallest observed make 1/20 of solar mass. The most massive stars generally have a mass from approximately 50 to 80 solar masses. The stars even more massive are unstable because immense the Pression of radiation which reigns in their center causes the expulsion of the matter which constitutes them.

In January 2004, Stephen Eikenberry of the University of California, announced to have found the star most massive ever observed: LBV 1806-20 . It is about a very young star which would make at least 150 solar masses.
