Abstract

Eclipsing brown dwarfs are important calibrators of sub-stellar evolution models used to infer the characteristics of directly imaged brown dwarfs and giant exoplanets. Only two double brown dwarf eclipsing binary systems are known, among them 2MASS J15104786-2818174 (2M1510 AB), published in 2020 with a poorly constrained orbital period. The TESS full-frame image (FFI) photometry of this double line eclipsing binary has been analysed, and its orbital period refined to 20.897782 ± 0.000036 d, reducing its present-day uncertainty from 18 h to 8 min.
