Understanding of R 136a 1 star

Paul crowther, an astronomer at the University of Sheffield, and his research team recalculated the observation data of the Hubble Space Telescope and the European Southern Observatory, and found that the mass of this star in the Tarantula Nebula of the Large Magellanic Galaxy, code-named R 136a 1, set a record.

For example, the British "Daily Telegraph" said that if R 136a 1 is put into the solar system, its brightness relative to the sun is equivalent to the brightness of the sun relative to the moon.

The previously known stars with the largest mass include: pistol star, whose mass is equivalent to 80 to 150 suns; The mass of the Ita constellation (Haishan II) at the bottom of the ship is about 120 suns. They are all dwarfed by R 136a 1. According to the Eddington limit, the greater the mass of a star, the more light it can emit, and the excessive radiation pressure will also make the star unstable. A star with a mass more than 50 times that of the sun cannot be stable. It is generally believed that the solar mass of 150 times is the upper limit of Eddington limit. Crozet thinks that R 136a 1 is close to the limit, and "this new record cannot be broken in a short time". However, R 136a 1 is now eroded by a powerful cosmic storm, and its quality is gradually declining.
