Question
If P is the average power output of our sun, what was the average power output (in terms of P) of this magnetar?
Express using two sigfigs.
P-subscript(av-m) = ?
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, what was the average power output (in terms of P) of this magnetar?Explanation / Answer
energy release by sun is E_sun =P*A*ts.......=Energy released by megastar=P_(av-m)*A*tm....
P_(av-m)=P*A*ts/(A.tm)=P*25*10^4*365*24*3600/0.2=3.942*10^13*P
P_(av-m)=3.942*10^13*P
