What is the total power out of star X compared w our sun?
Star X is 1/4 the size of our sun and has a surface temperature twice that of our sun. What is the total power out of this star compared w/ our sun?...Looking for something like...stars power out is X times that of our sun.
Assuming you mean 1/4 the diameter....
The surface area of star X would be 1/64 of Sol's. Its emissivity per unit area would be 16x Sol's (blackbody radiation increases as temperature to the fourth power), so its total power emission would be 1/4 of Sol's.
