Temperature vs luminosity for mass

Web11 Jan 2024 · Luminosity is a measure of the energy radiated by an object, for example, a star or a galaxy. For the stars of the main sequence, luminosity is directly related to their temperature – the hotter a star, the more luminous it is. On the other hand, cooler stars emit less energy – hence, it's more challenging to spot them in the night sky. WebMass loss For massive stars, mass loss in stellar winds means that the present mass is smaller than the initial mass. These difficulties mean that although the local IMF is well determined for masses between ~0.5 Msun and ~50 Msun: • not well determined at the very low mass end (mainly because the relation between luminosity and mass
