Problem: 2152622 results for On December 27, 2004, astronomers observed the greatest flash of light ever recorded from outside the solar system. It came from the highly magnetic neutron star SGR 180-20(a magnetar). During 0.20 s, this star released as much energy as our sun does in 250000 years. If P is the average power output of our sun,
Part A: What was the average power output (in terms of P) of this magnetar?
I need help to compute the average power output (in terms of P) of this magnetar.
