Distinguishing Circumstellar from Stellar Photometric Variability in Eta Carinae
Augusto Damineli, Eduardo Fernández-Lajús, Leonardo A. Almeida +14
The interacting binary Eta Carinae remains one of the most enigmatic massive stars in our Galaxy despite over four centuries of observations. In this work, its light curve from the…
Studying the photometric and spectroscopic variability of the magnetic hot supergiant Orionis Aa
B. Buysschaert, C. Neiner, N. D. Richardson +14
Massive stars play a significant role in the chemical and dynamical evolution of galaxies. However, much of their variability, particularly during their evolved supergiant stage, i…
Understanding the photometric variability of ζ Ori Aa
B. Buysschaert, C. Neiner, T. Ramiaramanantsoa +3
We studied the variability of the magnetic O-type supergiant Ori Aa using multi-colour BRITE photometry. We confirmed the known rotation frequency …
Characterizing the Rigidly Rotating Magnetosphere Stars HD 345439 and HD 23478
J. P. Wisniewski, S. D. Chojnowski, J. R. A. Davenport +8
The SDSS III APOGEE survey recently identified two new Ori E type candidates, HD 345439 and HD 23478, which are a rare subset of rapidly rotating massive stars whose large (kGa…
The Optical Wind Line Variability of Carinae During the 2009.0 Event
Noel D. Richardson, Douglas R. Gies, Theodore R. Gull +2
We report on high-resolution spectroscopy of the 2009.0 spectroscopic event of Carinae collected via SMARTS observations using the CTIO 1.5 m telescope and echelle spectrograph…
