Visual Orbits of Spectroscopic Binaries with the CHARA Array. V. HD 210763 and HD 221950
Kathryn V. Lester, Josephine Singleton, Alexandra M. Twomey +16
We present the visual orbits and dynamical masses of two longer period spectroscopic binary stars, HD 210763 and HD 221950, using long baseline interferometry with the CHARA Array…
The Solar Neighborhood LV: Spectral Characterization of an Equatorial Sample of 580 K Dwarfs
Hodari-Sadiki Hubbard-James, Sebastian Carrazco-Gaxiola, Todd J. Henry +5
We present a spectroscopic characterization of 580 K dwarfs within 33 pc, observed with the CHIRON echelle spectrograph (R=80,000) on the SMARTS 1.5m telescope. This volume-limited…
Arecibo Wow! II: Revised Properties of the Wow! Signal from Archival Ohio SETI Data
Abel Méndez, Kevin N. Ortiz Ceballos, Jorge I. Zuluaga +8
The Wow! Signal, detected in 1977 by the Ohio State University SETI project, remains one of the most intriguing unexplained radio transients. The most recent significant revision o…
A Radio Flaring, Chromospherically-Inactive K Dwarf
Dale A. Frail, Scott D. Hyman, Michele L. Silverstein +10
We report on an unusual radio source J180526-292953, initially identified as a steep spectrum, polarized point source toward the Galactic bulge and found to coincide with the nearb…
Mind the Gap I: H Activity of M Dwarfs Near the Partially/Fully Convective Boundary and a New H Emission Deficiency Zone on the Main Sequence
Wei-Chun Jao, Todd J. Henry, Russel J. White +3
Since identifying the gap in the H-R Diagram (HRD) marking the transition between partially and fully convective interiors, a unique type of slowly pulsating M dwarf has been propo…
The Solar Neighborhood L: Spectroscopic Discovery of K Dwarfs Younger Than 1 Gyr and New Binaries within 30 pc
Hodari-Sadiki Hubbard-James, D. Xavier Lesley, Todd J. Henry +2
As part of a comprehensive effort to characterize the nearest stars, the CHIRON echelle spectrograph on the CTIO/SMARTS 1.5m telescope is being used to acquire high resolution (R =…
