description R136a1 Overview
R136a1 is an extremely massive Wolf-Rayet star located within the R136 star cluster in the Large Magellanic Cloud. It is estimated to have an initial mass of roughly 300 solar masses, making it one of the most massive known stars in the universe. The star is highly luminous and is shedding mass rapidly through strong stellar winds. It is a focal point for astronomers studying the upper limits of stellar formation.
help R136a1 FAQ
How massive is R136a1 compared with the Sun?
Models suggest R136a1 formed with an initial mass of around 300 times that of the Sun, although its present mass is lower because of intense stellar winds. Such estimates depend on atmospheric and evolutionary models rather than placing the star on a scale.
Where is R136a1 located?
R136a1 lies in the dense R136 cluster inside the Tarantula Nebula. That region is in the Large Magellanic Cloud, a satellite galaxy of the Milky Way roughly 160,000 light-years away.
What type of star is R136a1?
R136a1 is an extremely luminous Wolf-Rayet star with a very hot surface and powerful stellar winds. Its spectrum and inferred mass place it among the most extreme stars known.
Will R136a1 eventually become a supernova?
A star this massive is expected to end through a catastrophic collapse after a short life measured in only a few million years. Its exact fate is uncertain because heavy mass loss could substantially change its final mass before collapse.
