Astrometry and Photometry for 1000 L, T, and Y Dwarfs from the UKIRT Hemisphere Survey
Adam C. Schneider, Jeffrey A. Munn, Frederick J. Vrba +5
We present positions, proper motions, and near-infrared photometry for 966 known objects with spectral types later than M observed as part of the the UKIRT Hemisphere Survey (UHS).…
Redder than Red: Discovery of an Exceptionally Red L/T Transition Dwarf
Adam C. Schneider, Adam J. Burgasser, Justice Bruursema +26
We present the discovery of CWISE J050626.96073842.4 (CWISE J05060738), an L/T transition dwarf with extremely red near-infrared colors discovered through the Backyard Worlds…
Substellar Hyades Candidates from the UKIRT Hemisphere Survey
Adam C. Schneider, Frederick J. Vrba, Jeffrey A. Munn +14
We have used data from the UKIRT Hemisphere Survey (UHS) to search for substellar members of the Hyades cluster. Our search recovered several known substellar Hyades members, and t…
Radial Velocities of 41 Kepler Eclipsing Binaries
Rachel A. Matson, Douglas R. Gies, Zhao Guo +1
Eclipsing binaries are vital for directly determining stellar parameters without reliance on models or scaling relations. Spectroscopically derived parameters of detached and semi-…
Red Supergiants as Cosmic Abundance Probes: The Sculptor Galaxy NGC 300
J. Zachary Gazak, Rolf Kudritzki, Chris Evans +9
We present a quantitative spectroscopic study of twenty-seven red supergiants in the Sculptor Galaxy NGC 300. J-band spectra were obtained using KMOS on the VLT and studied with st…
The Multiplicity of Massive Stars: A High Angular Resolution Survey with the HST Fine Guidance Sensor
E. J. Aldoretta, S. M. Caballero-Nieves, D. R. Gies +11
We present the results of an all-sky survey made with the Fine Guidance Sensor on Hubble Space Telescope to search for angularly resolved binary systems among the massive stars. Th…
An Interferometric and Spectroscopic Analysis of the Multiple Star System HD 193322
Theo A. ten Brummelaar, David P. O'Brien, Brian D. Mason +15
The star HD 193322 is a remarkable multiple system of massive stars that lies at the heart of the cluster Collinder 419. Here we report on new spectroscopic observations and radial…
ASAS Light Curves of Intermediate Mass Eclipsing Binaries and the Parameters of HI Mon
S. J. Williams, D. R. Gies, J. W. Helsel +2
We present a catalog of 56 candidate intermediate mass eclipsing binary systems extracted from the 3rd data release of the All Sky Automated Survey. We gather pertinent observation…
The Evolutionary State of the Massive Interacting Binary BD+36 4063
S. J. Williams, D. R. Gies, R. A. Matson +1
We present a spectroscopic and photometric analysis of the remarkable massive binary system, BD +36 4063. We argue that the visible ON star is undergoing a rapid mass transfer epis…
