Question
If the maximum luminosity of a Type Ia supernova is $10^{10} L_{\odot}$ and the supernova remains at this brightness for 15 days, estimate how long our Sun would take to emit the same amount of energy.
Step 1
Luminosity is the amount of energy emitted per unit time, so we can find the total energy by multiplying the luminosity by the time: Energy_supernova = Luminosity_supernova × Time_supernova Energy_supernova = (10^10 L_☉) × (15 days) Now, we need to convert 15 Show more…

A supernova's energy is often compared to the total energy output of the Sun over its lifetime. Using the Sun's current energy output, calculate its total energy output, assuming that the sun has a $10^{10}$ year main-sequence lifetime. How does this compare with the energy released by a supernova?
How long does it take the blast wave from the center of a star undergoing a supernova to reach the star's surface if the blast wave is traveling at $10,000 \mathrm{km} /$ sec and the star is about 100 times the size of the Sun?
A supernova can eject material at a velocity of $10,000 \mathrm{km} / \mathrm{s}$. How long would it take a supernova remnant to expand to a radius of 1 AU? How long would it take to expand to a radius of 1 light-years? Assume that the expansion velocity remains constant and use the relationship: expansion time $=\frac{\text { distance }}{\text { expansion velocity }}$.
