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. WebLuminosity vs. Temperature of Stars (in Solar neighborhood) L=4πR2σT4 Main Sequence * most nearby stars (85%) & the sun * hydrogen-burning stars * 3000-30,000 K * 0.1 to 10 …

WebStefan's Law says that for any radiating object its luminosity, temperature and radius are related by this simple formula: 4 2 4 T R L EQ #1 where L is the luminosity, R is the radius, T is the surface temperature, = 3.141 and = 5.671 x 10-8 Watt/m2 K4. This means that if we measure the luminosity and temperature of a WebWhere luminosity and mass are based on the Sun = 1. So, if a star is 3 times more massive than the Sun, it will have a luminosity that is 46.8 times brighter. 3 3.5 = 46.8 Since we have calculated the luminosity, we can calculate the absolute magnitude with this formula: Absolute Magnitude = 4.83 ⚊2.5 • log 10 (46.8)
