Discovery of Two Very Wide Binaries with Ultracool Companions and a New Brown Dwarf at the L/T Transition
Koraljka Muzic, Jacqueline Radigan, Ray Jayawardhana +11
We present the discovery and spectroscopic follow-up of a nearby late-type L dwarf (2M0614+3950), and two extremely wide very-low-mass binary systems (2M0525-7425AB and 2M1348-1344…
