NGTS clusters survey โ€“ III. A low-mass eclipsing binary in the Blanco 1 open cluster spanning the fully convective boundary

ABSTRACT We present the discovery and characterization of an eclipsing binary identified by the Next Generation Transit Survey in the โˆผ115-Myr-old Blanco 1 open cluster. NGTS J0002โˆ’29 comprises three M dwarfs: a short-period binary and a companion in a wider orbit. This system is the first well-characterized, low-mass eclipsing binary โ€ฆ
