Preliminary Trigonometric Parallaxes of 184 Late-T and Y Dwarfs and an Analysis of the Field Substellar Mass Function into the "Planetary" Mass Regime
J. Davy Kirkpatrick, Emily C. Martin, Richard L. Smart +16
We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using observations from Spitzer (143), USNO (18), NTT (14), and UKIRT (9). To complete the 20-pc census o…
Probing Late-type T dwarf J-H Color Outliers for Signs of Age
Sarah E. Logsdon, Gregory N. Mace, Ian S. McLean +1
We present the results of a Keck/NIRSPEC follow-up survey of thirteen late-type T dwarfs (T6-T9), twelve of which have unusually red or blue J-H colors. Previous work suggests that…
IGRINS Spectral Library
Sunkyung Park, Jeong-Eun Lee, Wonseok Kang +12
We present a library of high-resolution (R / 45,000) and high signal-to-noise ratio (S/N 200) near-infrared spectra for stars of a wide range of spe…
Chemical Compositions of Evolved Stars From Near-Infrared IGRINS High-Resolution Spectra. I. Abundances in Three Red Horizontal Branch Stars
Melike Afşar, Christopher Sneden, Michael P. Wood +6
We have derived elemental abundances of three field red horizontal branch stars using high-resolution (R 45,000), high signal-to-noise ratio (S/N 200) and …
Multi-band high resolution spectroscopy rules out the hot Jupiter BD+20 1790b - First data from the GIARPS Commissioning
I. Carleo, S. Benatti, A. F. Lanza +51
Context. Stellar activity is currently challenging the detection of young planets via the radial velocity (RV) technique. Aims. We attempt to definitively discriminate the nature o…
Magnetic Inflation and Stellar Mass II: On the Radii of Single, Rapidly Rotating, Fully Convective M Dwarf Stars
Aurora Y. Kesseli, Philip S. Muirhead, Andrew W. Mann +1
Main sequence, fully-convective M dwarfs in eclipsing binaries are observed to be larger than stellar evolutionary models predict by as much as . A proposed explanation fo…
High-resolution near-IR Spectral mapping with H and [Fe II] lines of Multiple Outflows around LkH 234
Heeyoung Oh, Tae-Soo Pyo, Bon-Chul Koo +11
We present a high-resolution, near-IR spectroscopic study of multiple outflows in the LkH 234 star formation region using the Immersion GRating INfrared Spectrometer (IGRINS). S…
New Y and T dwarfs from WISE identified by Methane Imaging
C. G. Tinney, J. Davy Kirkpatrick, Jacqueline K. Faherty +6
We identify new Y- and T-type brown dwarfs from the WISE All Sky data release using images obtained in filters that divide the traditional near-infrared H and J bands into two halv…
Wolf 1130: A Nearby Triple System Containing a Cool, Ultramassive White Dwarf
Gregory N. Mace, Andrew W. Mann, Brian A. Skiff +9
Following the discovery of the T8 subdwarf WISEJ200520.38+542433.9 (Wolf 1130C), with common proper motion to a binary (Wolf 1130AB) consisting of an M subdwarf and a white dwarf,…
