What surface temperature estimate is frequently associated with R136a1, located in the Large Magellanic Cloud?
Answer
Around 50,000 K
R136a1 serves as a key reference point when discussing extreme stellar surface heat. This star, known for being incredibly massive and luminous within the Large Magellanic Cloud, is estimated to possess a surface temperature hovering near 50,000 Kelvin according to some astronomical sources. While this level of heat is sufficient to cause nearly complete ionization of surrounding elements, it is important to recognize this measurement represents only the photosphere, or the visible 'skin' of the star, distinguishing it significantly from its core temperature.
