The Solar Neighborhood LVI: The RMSTAR Catalog of the Nearest 3352 M Dwarf Systems and 305 of their Wide Companions
Madison R. LeBlanc, Tim M. Johns, Todd J. Henry +8
We present the RMSTAR (RECONS M STAR) catalog, a 25 pc volume-limited and effectively volume-complete sample of the nearest 3352 M dwarf systems and their 305 wide stellar and 9 br…
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 Debris Disk Host Piscis Austrinus is a Rapidly Rotating Star Seen Nearly Pole-On
Colin Kane, Russel White, Jeremy Jones +6
Previous studies of Piscis Austrinus (PsA) have speculated that the narrow and saddle-like shapes of some of its weak metallic lines are a consequence of it being a rapidly rot…
The Solar Neighborhood LIV: 54 Orbits of M Dwarf Multiples within 30 Parsecs with Speckle Interferometry at SOAR
Eliot Halley Vrijmoet, Andrei Tokovinin, Todd J. Henry +3
We present 1066 speckle measurements of M dwarf multiples observed over 2021-2024, all taken with HRCam on the Southern Astrophysical Research 4.1 m telescope. Among these, 900 obs…
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…
The Solar Neighborhood LII: M Dwarf Twin Binaries -- Presumed Identical Twins Appear Fraternal in Variability, Rotation, H, and X-rays
Andrew A. Couperus, Todd J. Henry, Rachel A. Osten +4
We present an investigation into the rotation and stellar activity of four fully convective M dwarf `twin' wide binaries. Components in each pair have (1) astrometry confirming the…
