A not so massive cluster hosting a very massive star

Abstract

We present the first physical characterization of the young open cluster VVV CL041. We spectroscopically observed the cluster main-sequence stellar population and a very-massive star candidate: WR62-2. CMFGEN modeling to our near-infrared spectra indicates that WR62-2 is a very luminous (10${}^{6.4\pm 0.2}{L}_{\odot }$) and massive ($\sim 80M_{\odot }$) star.
