Question

Which is related to the LUMINOSITY of stars?A. distanceB. massC. neither are related to luminosityD. both are related to luminosity

Answer 1

The more distant a star is, the fainter will be the apparent luminosity.

Also, the mass-luminosity relationship is given by the equation below:

`(L)/(L_S)=((M)/(M_S))^a`

Where Ls and Ms are the mass and luminosity of the sun and 1 < a < 6.

Therefore the correct option is D.
