A quasar consumes 1 solar mass of material per year, converting 15 percent of it directly into energy. What is the quasar’s luminosity, in solar units?
##L = 1.478 xx 10^13 L_o.## Quasars are created as a result of mas being swallowed by the supermassive black hole at the center of an active galactic nucleus. The luminosity of a quasar is the rate at which energy is emitted by the quasar. We are given the rate of ##1 M_o. “/ yr”##, …
