The Extremely Red, Young L Dwarf PSO J318-22: A Free-Floating Planetary-Mass Analog to Directly Imaged Young Gas-Giant Planets
Michael C. Liu, Eugene A. Magnier, Niall R. Deacon +16
We have used Pan-STARRS1 to discover an extremely red late-L dwarf, which has (J-K)_MKO = 2.84 and (J-K)_2MASS = 2.78, making it the reddest known field dwarf and second only to 2M…
A Near-Infrared Spectroscopic Study of Young Field Ultracool Dwarfs: Additional Analysis
K. N. Allers, Michael C. Liu
We present additional analysis of the classification system presented in Allers & Liu (2013). We refer the reader to Allers & Liu (2013) for a detailed discussion of our near-IR sp…
Infrared Parallaxes of Young Field Brown Dwarfs and Connections to Directly Imaged Gas-Giant Exoplanets
Michael C. Liu, Trent J. Dupuy, Katelyn N. Allers
We have measured high-precision parallaxes for a large sample of candidate young (~10-100 Myr) and intermediate-age (~100-600 Myr) ultracool dwarfs, with spectral types ranging fro…
A Near-Infrared Spectroscopic Study of Young Field Ultracool Dwarfs
K. N. Allers, Michael C. Liu
We present a near-infrared (0.9-2.4 microns) spectroscopic study of 73 field ultracool dwarfs having spectroscopic and/or kinematic evidence of youth (~10-300 Myr). Our sample is c…
