WISEA J064750.85-154616.4: a new nearby L/T transition dwarf.


Abstract (from CDS):

Our aim is to detect and classify previously overlooked brown dwarfs in the solar neighbourhood. We performed a proper motion search among bright sources observed with the Wide-field Infrared Survey Explorer (WISE) that are also seen in the Two Micron All Sky Survey (2MASS). Our candidates appear according to their red J-Ks colours as nearby late-L dwarf candidates. Low-resolution near-infrared (NIR) classification spectroscopy in the HK band allowed us to get spectroscopic distance and tangential velocity estimates. We have discovered a new L9.5 dwarf, WISEA J064750.85-154616.4, at a spectroscopic distance of about 14pc and with a tangential velocity of about 11km/s, typical of the Galactic thin disc population. We have confirmed another recently found L/T transition object at about 10pc, WISEA J140533.13+835030.7, which we classified as L8 (NIR).
