Mass-to-Light Ratios of Spatially Resolved Stellar Populations in M31

O. Grace Telford, Julianne J. Dalcanton, Benjamin F. Williams +4

A galaxy's stellar mass-to-light ratio ($M_{\star }/L$) is a useful tool for converting luminosity to stellar mass ($M_{\star }$). However, the practical utility of $M_{\star }/L$ inferred…
