Spectroscopic Line Modeling of the Fastest Rotating O-type Stars
Katherine Shepard, Douglas R. Gies, Lex Kaper +1
We present a spectroscopic analysis of the most rapidly rotating stars currently known, VFTS 102 ( km s; O9: Vnnne+) and VFTS 285 ($v_{e} \sin i =…
Mass Transfer as an Explanation for the Lifetime-Travel Time Discrepancy in IT Librae
Peter Wysocki, Douglas Gies, Katherine Shepard +2
The eclipsing binary IT Librae is an unusual system of two B-type stars that is situated about 1 kpc above the galactic plane. The binary was probably ejected from its birthplace i…
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…
HST/COS Spectra of the Wind Lines of VFTS 102 and 285
Katherine Shepard, Douglas R. Gies, Kathryn V. Lester +5
Rapid rotation in massive stars imposes a latitudinal variation in the mass loss from radiatively driven winds that can lead to enhanced mass loss at the poles (with little angular…
