A Multi-Method Age Determination for the Ursa Major Moving Group
Julia Sheffler, Max Clark, Melinda Soares-Furtado +4
The Ursa Major Moving Group (UMa) is one of the closest stellar associations, yet its age has remained controversial, with published estimates ranging from 200 Myr to 1 Gyr. We pre…
13 Years of P Cygni Spectropolarimetry: Investigating Mass-loss Through H, Periodicity, and Ellipticity
Keyan Gootkin, Trevor Dorn-Wallenstein, Jamie R. Lomax +7
We report on over 13 years of optical and near-ultraviolet spectropolarimetric observations of the famous Luminous Blue Variable (LBV), P Cygni. LBVs are a critical transitional ph…
Spectropolarimetry of the WR + O Binary WR42
Andrew G. Fullard, Jennifer L. Hoffman, Sophia DeKlotz +3
We present new spectropolarimetric data for WR 42 collected over 6 months at the 11-m Southern African Large Telescope (SALT) using the Robert Stobie Spectrograph.
The Complex Circumstellar and Circumbinary Environment of V356 Sgr
Jamie R. Lomax, Andrew G. Fullard, Michael A. Malatesta +13
We analyze 45 spectropolarimetric observations of the eclipsing, interacting binary star V356 Sgr, obtained over a period of 21 years, to characterize the geometry of the system's…
Abell 48 - a rare WN-type central star of a planetary nebula
H. Todt, A. Y. Kniazev, V. V. Gvaramadze +18
A considerable fraction of the central stars of planetary nebulae (CSPNe) are hydrogen-deficient. Almost all of these H-deficient central stars (CSs) display spectra with strong ca…
Multi-Wavelength Observations of Supernova 2011ei: Time-Dependent Classification of Type IIb and Ib Supernovae and Implications for their Progenitors
D. Milisavljevic, R. Margutti, A. M. Soderberg +39
We present X-ray, UV/optical, and radio observations of the stripped-envelope, core-collapse supernova (SN) 2011ei, one of the least luminous SNe IIb or Ib observed to date. Our ob…
