Only main sequence stars have a well-defined relationship between spectral type and luminosity.
Explanation:
Low-mass stars have much longer lifetimes than high-mass stars.
Answer:
The answer is 20727w
Explanation:
The formula is below;
P = d r^2 v^3 *efficiency
In the question, it is stated that the registration ignores efficiency so we are going to ignore efficiency in the equation and use it this way;
P = d r^2 * v^3
d =4.3, r = 1.59, v =n 12.4
Therefore, P = 4.3 X 1.59^2 X 12.4^3 = 20727W
