Discovery of a Mid-L Dwarf Companion to the L 262-74 System
Abstract
We present the discovery of CWISE J151044.74-524923.5, a wide low-mass companion to the nearby (24.7 pc) system L 262-74, which was identified through the Backyard Worlds: Planet 9 citizen science project. We detail the properties of the system, and we assess that this companion is a mid-L dwarf, which will need to be verified spectroscopically. With an angular separation of 743, we estimate a projected physical separation of 1837 au from the central system.
