Description

We report the discovery and characterization of a new M-dwarf binary, with component masses and radii of M<inf>1</inf> = 0.244+0.003<inf>-0.003</inf> M<inf>⊙</inf>, R<inf>1</inf> = 0.261+0.006<inf>-0.009</inf> R<inf>⊙</inf>, M<inf>2</inf> = 0.179+0.002<inf>-0.001</inf> M<inf>⊙</inf>, R<inf>2</inf> = 0.218+0.007<inf>-0.011</inf> R<inf>⊙</inf>, and orbital period of ~4.1 d. The M-dwarf binary HATS551Š027 (LP 837Š20) was identified as an eclipsing binary by the HATSouth survey, and characterized...[Show more]
