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…

The First Habitable Zone Earth-sized Planet from TESS. I: Validation of the TOI-700 System
Emily A. Gilbert, Thomas Barclay, Joshua E. Schlieder +92
We present the discovery and validation of a three-planet system orbiting the nearby (31.1 pc) M2 dwarf star TOI-700 (TIC 150428135). TOI-700 lies in the TESS continuous viewing zo…
