The Mega Star of the Galaxy

Canadian scientists have discovered the most massive star so far in the Milky Way.

Researchers from Montreal University in collaboration with an international team of astrophysicists, have found that the super-massive star has a mass 116 times that of the sun.

Though theoretical models of stellar formation hint at the possibility of stars that can be 150 times the mass of the sun, no star 100 times the mass of the sun has been discovered yet.

The researchers Olivier Schnurr, Jules Casoli and Andr -Nicolas Chen , Anthony Moffat and Nicole St-Louis discovered the super-massive star in the company of yet another massive star whose mass is also 89 times that of the sun.

These two massive stars form a binary system, with the lighter star waltzing around its heavier companion. They have a rotation period of 3.77 days.

Located in the massive star cluster NGC 3603 of the Milky Way, the super-massive two-star binary system has been named A1, a university statement said.

The two stars are so massive and bright that the light they transmit shows characteristics that only Wolf-Rayet stars possess.

A Wolf-Rayet star is a hot, massive and evolved star exhibiting a very high loss of mass due to a strong stellar wind (similar to the solar wind), the statement said.
