A 1.48-2.48 m R=28000 spectroscopic atlas of the L7.5 and T0.5 components of the nearest pair of brown dwarfs: Luhman 16AB
Hiroyuki Tako Ishikawa, Stanimir Metchev, Megan E. Tannock +6
We present a high signal-to-noise (SNR 450), high-dispersion () H- and K-band spectroscopic atlas of the L7.5 and T0.5 components of the Luhman 1…
A 1.46-2.48 m Spectroscopic Atlas of a T6 Dwarf (1060 K) Atmosphere with IGRINS: First Detections of HS and H, and Verification of HO, CH, and NH Line Lists
Megan E. Tannock, Stanimir Metchev, Callie E. Hood +5
We present Gemini South/IGRINS observations of the 1060 K T6 dwarf 2MASS J081730016155158 with unprecedented resolution () and signal-to-noise ratio (SNR >…
Weather on Other Worlds. V. The Three Most Rapidly Rotating Ultra-Cool Dwarfs
Megan E. Tannock, Stanimir Metchev, Aren Heinze +7
We present the discovery of rapid photometric variability in three ultra-cool dwarfs from long-duration monitoring with the Spitzer Space Telescope. The T7, L3.5, and L8 dwarfs hav…
A Statistical Survey of Peculiar L and T Dwarfs in SDSS, 2MASS, and WISE
Kendra Kellogg, Stanimir Metchev, Paulo A. Miles-Páez +1
We present the final results from a targeted search for brown dwarfs with unusual near-infrared colors. From a positional cross-match of SDSS, 2MASS and WISE, we have identified 14…
