Discovery of the Young L Dwarf WISE J1741102.78-464225.5
Adam C. Schneider, Michael C. Cushing, J. Davy Kirkpatrick +5
We report the discovery of the L dwarf WISE J174102.78464225.5, that was discovered as part of a search for nearby L dwarfs using the Wide-field Infrared Survey Explorer (WISE).…
The Kappa Andromedae System: New Constraints on the Companion Mass, System Age & Further Multiplicity
Sasha Hinkley, Laurent Pueyo, Jacqueline K. Faherty +29
Kappa Andromedae is a B9IVn star at 52 pc for which a faint substellar companion separated by 55 AU was recently announced. In this work, we present the first spectrum of the compa…
Discovery of the Y1 Dwarf WISE J064723.23-623235.5
J. Davy Kirkpatrick, Michael C. Cushing, Christopher R. Gelino +5
We present the discovery of a very cold, very low mass, nearby brown dwarf using data from the NASA Wide-field Infrared Survey Explorer (WISE). The object, WISE J064723.23-623235.5…
A deep WISE search for very late type objects and the discovery of two halo/thick-disk T dwarfs: WISE 0013+0634 and WISE 0833+0052
D. J. Pinfield, J. Gomes, A. C. Day-Jones +21
A method is defined for identifying late T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and uses the statistical p…
Young Brown Dwarfs as Giant Exoplanet Analogs
Jacqueline K. Faherty, Kelle L. Cruz, Emily L. Rice +1
Young brown dwarfs and directly-imaged exoplanets have enticingly similar photometric and spectroscopic characteristics, indicating that their cool, low gravity atmospheres should…
Luhman 16AB: A Remarkable, Variable L/T Transition Binary 2 pc from the Sun
A. J. Burgasser, J. Faherty, Y. Beletsky +12
Luhman (2013) has reported the discovery of a brown dwarf binary system only 2.01+/-0.15 pc from the Sun. The binary is well-resolved with a projected separation of 1.5", and spect…
