Arandom star has a surface temperature of 7300 k and a radius 100 times that of the sun. calculate the luminosity of the star compared to the sun. estimate what it’s apparent magnitude would be if it was only ∼ 1 pc away like the nearest stars. compare this to other night sky objects.

Explanation:

given data:

surface temperature 7300 K

we know that

Where

A area of illuminated surface

T = temperature of surface

WE KNOW THAT

T = 7300 K

L = L_O * 2.54*10^4

WE KNOW THAT

r = 1 parsec, pc = 3.085*10^{16] m

luminosity decrease when move away from the core
