WebThere is a relationship between mass and luminosity for stars in the "hydrogen" burning phase of their life cycle (the so called "main sequence"). This formula estimates the … WebThe vertical axis is marked in billions of solar luminosities. A “solar luminosity” is the light power of the Sun (given below). So the plot says that for the few weeks near maximum luminosity, a supernova shines with more energy than a billion suns. The horizontal axis is time since the explosion occurred, in days.
