I am stuck on 2 questions please help if you can.
We assumed that for every 1 solar luminosity that we see, there are 2 solar masses of matter.
How would our assumption for the among of luminous matter change if NGC 2742 has more low mass stars that we thought, but remains just as luminous? Remember that a stars luminosity depends sensitively on its mass.
How would this affect the mass to light ratio?
I would think it would stay the same correct?
