# The mass lost by Sun per second

I understand that the question is not relevant, but I think that on habré a lot of people with good knowledge of physics. Today helped the younger brother to solve problems in physics, one is soporose and wild interest was inflating me. Myself quantum physics and optics like a good idea remember, though it's been 4 years, but then a complete stupor, it is interesting to understand.

In tasks with only a full flow of energy radiated by the sun. From what ottolknutsya, tell me?

E=mc^2?

Take the mass of the sun in any arbitrary moment in time and subtract its weight in one second, the difference will be the answer.

Roughly (for a blackbody):
$E = \sigma T^4 4\pi R^2t = mc^2$
Temperature 6000 K, time 1 sec, the radius of 700,000 km, the speed of light and the Stefan-Boltzmann constant known
Damn. Inadvertently could that the left side is known and so :) - mittie commented on October 8th 19 at 02:46
The middle equation is generally valid because, AFAIK, it only works for thermal electromagnetic radiation. And there is also nonthermal gamma-ray and charged particles. - nikita.Stracke commented on October 8th 19 at 02:49
