Abstract: First spectroscopic and new photometric observations of the eclipsing Algol-type binary FM Leo are presented. JKTEBOP, Wilson-Devinney binary modeling codes, and TODCOR methods were applied for the analysis to derive stellar and orbital parameters. With masses and radii determined better than 1% and 4%, respectively, we compared the observations with current stellar evolution models interpolated for the system and found the evolutionary status and age of FM Leo.
