a. it rotates faster
b. it is smaller
c. it is more luminous
d. it has stronger pulses
I'm stumped on this practice question for my final. I'm thinking that a. and d. contradict each other since doesn't an older, slower rotating neutron strong emit longer, stronger pulses? C. seems to...
Sorry. I meant to say galaxy instead of star.
AGN = Active Galactic Nuclei
I am given a luminosity of 12 trillion solar luminosities, and I need to find its mass.
How would someone find the mass of an AGN when a solar luminosity is given? I know you can't simply use the mass-luminosity relationship since that only applies to main sequence stars, right?
Thanks.
