Problem 51E
Magnetar. ?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 1806-20 (a ?magnetar?). During 0.20 s, this star released as much energy as our sun does in 250,000 years. If P is the average power output of our sun, what was the average power output (in terms of P) of this magnetar?
Step-by-Step Solution:
Solution 51 E Step 1: Data given Time of flash t = 0.20 s Energy released by sun P = P × 250,000 years S The average power is obtained as 250,000 years(86400s ×365 days ) Pavg = P 0.20 s P = P × 3.9 × 10 13 avg 13 Hence we get the average power output as P avg = 3.9 × 10 P
