TIC441725813: A new bright hybrid sdB pulsator with differential core/envelope rotation
Wenchao Su, Stéphane Charpinet, Marilyn Latour +3
We present the detailed analysis of a new hybrid (p- and g-mode) sdB pulsator, TIC441725813 (TYC 4427-1021-1), discovered and monitored by TESS over 670 days. The TESS light curves…
Multi-epoch Spectropolarimetry of SN 2011fe
Peter A. Milne, G. Grant Williams, Amber Porter +5
We present multiple spectropolarimetric observations of the nearby Type Ia supernova (SN) 2011fe in M101, obtained before, during, and after the time of maximum apparent visual bri…
Spectral analysis of the sdO standard star Feige 34
M. Latour, P. Chayer, E. M. Green +1
We present our current work on the spectral analysis of the hot sdO star Feige 34. We combine high S/N optical spectra and fully-blanketed non-LTE model atmospheres to derive its f…
A NLTE analysis of the hot subdwarf O star BD+28 4211. II. The optical spectrum
M. Latour, G. Fontaine, E. M. Green +1
We present the second part of our detailed analysis of the hot sdO and spectroscopic standard star BD+28 4211, in which we focus on the optical spectrum. In the first part of our s…
High-speed Photometric Observations of ZZ Ceti White Dwarf Candidates
E. M. Green, M. -M. Limoges, A. Gianninas +12
We present high-speed photometric observations of ZZ Ceti white dwarf candidates drawn from the spectroscopic survey of bright DA stars from the Villanova White Dwarf Catalog by Gi…
Improved determination of the atmospheric parameters of the pulsating sdB star Feige 48
M. Latour, G. Fontaine, E. M. Green +2
As part of a multifaceted effort to exploit better the asteroseismological potential of the pulsating sdB star Feige 48, we present an improved spectroscopic analysis of that star…
