Microlensing provides an alternative tool for the discovery and investigation of faint systems. In this thesis, I present the analysis of the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035, which is due to a binary system composed of a brown dwarf orbiting a red dwarf. After accurate modeling, the result I got is that the lens is composed of a red dwarf with mass 0.149±0.010M⊙ and a brown dwarf with mass 0.0463±0.0031M⊙, at a projected separation of 0.585 au.

Abstract
Microlensing provides an alternative tool for the discovery and investigation of faint systems. In this thesis, I present the analysis of the microlensing event OGLE-2019-BLG-0033/MOA-2019-BLG-035, which is due to a binary system composed of a brown dwarf orbiting a red dwarf. After accurate modeling, the result I got is that the lens is composed of a red dwarf with mass 0.149±0.010M⊙ and a brown dwarf with mass 0.0463±0.0031M⊙, at a projected separation of 0.585 au.| File | Dimensione | Formato | |
