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…
The Solar Neighborhood. LV. M Dwarf Twin Binaries -- One in Five Twin Sibling Pairs Are Mismatched in Activity and/or Rotation
Andrew A. Couperus, Todd J. Henry, Aman Kar +3
We report on a study of 36 pairs of `twin' M dwarfs in wide binaries and assess how similarly the stars behave. Stars in each twin pair have BP, RP, , , and differing b…
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…
Estimating the Convective Turnover Time
Wei-Chun Jao, Andrew A Couperus, Eliot H. Vrijmoet +2
The introduction of the Rossby number (R), which incorporates the convective turnover time (), in 1984 was a pioneering idea for understanding the correlation between stella…
The orbit and stellar masses of the archetype colliding-wind binary WR 140
Joshua D. Thomas, Noel D. Richardson, J. J. Eldridge +33
We present updated orbital elements for the Wolf-Rayet (WR) binary WR\,140 (HD\,193793; WC7pd + O5.5fc). The new orbital elements were derived using previously published measuremen…
Spectroscopic Detection of the Pre-White Dwarf Companion of Regulus
Douglas R. Gies, Kathryn V. Lester, Luqian Wang +6
Mass transfer in an interacting binary will often strip the mass donor of its entire envelope and spin up the mass gainer to near critical rotation. The nearby B-type star Regulus…
