Solar carbon abundance from 3D non-LTE modelling of the diagnostic lines of the CH molecule
Richard Hoppe, Maria Bergemann, Philipp Eitner +5
The spectral lines of the CH molecule are a key carbon (C) abundance diagnostic in FGKM-type stars. These lines are detectable in metal-rich and, in contrast to atomic C lines, als…
Long-term 4.6m Variability in Brown Dwarfs and a New Technique for Identifying Brown Dwarf Binary Candidates
Hunter Brooks, J. Davy Kirkpatrick, Aaron M. Meisner +11
Using a sample of 361 nearby brown dwarfs, we have searched for 4.6m variability indicative of large-scale rotational modulations or large-scale long-term changes on timescales…
Constraints on the Binarity of the WN3/O3 Class of Wolf-Rayet Stars
Philip Massey, Kathryn F. Neugent, Nidia I. Morrell
The WN3/O3 Wolf-Rayet (WR) stars were discovered as part of our survey for WRs in the Magellanic Clouds. The WN3/O3s show the emission lines of a high-excitation WN star and the ab…
Star-Crossed Lovers DI Tau A and B: Orbit Characterization and Physical Properties Determination
Shih-Yun Tang, Asa G. Stahl, L. Prato +5
The stellar companion to the weak-line T Tauri star DI Tau A was first discovered by the lunar occultation technique in 1989 and was subsequently confirmed by a speckle imaging obs…
A Survey for C II Emission-Line Stars in the Large Magellanic Cloud. II. Final Results and the Origin of C II Emission in [WC] Spectra
Bruce Margon, Nidia Morrell, Philip Massey +2
We present the final results of an imaging and spectroscopic search for stars in the Large Magellanic Cloud (LMC) with C II 7231, 7236 emission lines. The goal is to identify and s…
The Time-Averaged Mass-Loss Rates of Red Supergiants As Revealed by their Luminosity Functions in M31 and M33
Philip Massey, Kathryn F. Neugent, Sylvia Ekstrom +2
Mass-loss in red supergiants (RSGs) is generally recognized to be episodic, but mass-loss prescriptions fail to reflect this. Evolutionary models show that the total amount of mass…
