| Apr 19, 2014 at 2:54 | comment | added | AfroBoy | @Gerald Thank you so much. That makes total sense now. I understand M/L is only really for main sequence stars, but I have other corrections I can apply along the way to get a better estimate. Thank you! | |

The answer is obsolete.

| Apr 18, 2014 at 14:46 | comment | added | Gerald | @AfroBoy Thanks for the details! I'll try to solve it. The formula first given is applicable to main sequence stars, not necessarily to galaxies. | |
| Apr 18, 2014 at 14:34 | comment | added | AfroBoy | @Gerald Thanks again for your help. I think I'm getting confused in abstracts, so I've reworded the question with some more concrete details. | |

added more general version, applicable to other mass ranges

Added hint to restricted applicabiltity and necessary adjustments

Added simplification by using "Sun" units.

| Apr 18, 2014 at 10:44 | comment | added | Gerald | @AfroBoy On the right side of the equation you have the (probably known) $M_i/L_i$ mass-luminosity ratios. Might it be you confused $M_i$ with $M_*$ in this case? | |
| Apr 18, 2014 at 3:07 | comment | added | Py-ser | I guess you could just integrate over a reasonable range, better if tuned for your given galaxy. | |
| Apr 18, 2014 at 2:57 | comment | added | AfroBoy | thanks for that. That equation makes sense however $M_i$ is an unknown that I need to solve for, ye it's in both sides of the equation. | |
