A Multi-Year Photopolarimetric Study of the Semi-Regular Variable V CVn and Identification of Analogue Sources
Hilding Neilson, Nicolaus Steenken, John Simpson +4
The semi-regular variable star V Canum Venaticorum (V CVn) is well-known for its unusual linear polarization position angle (PA). Decades of observing V CVn reveal a nearly constan…
Peering into the tilted heart of Cyg X-1 with high-precision optical polarimetry
Vadim Kravtsov, Alexandra Veledina, Andrei V. Berdyugin +7
We present the high-precision optical polarimetric observations of black hole X-ray binary Cyg X-1, spanning several cycles of its 5.6 day orbital period. Week-long observations on…
Variability in Proto-Planetary Nebulae: VIII. A New Sample of Southern Hemisphere Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +5
As part of our continuing study of light variability in proto-planetary nebulae (PPNe), we present the results from a long-term study of nine southern hemisphere objects. We have m…
Modeling the Variable Polarization of epsilon Aurigae In and Out of Eclipse
Richard Ignace, Gary Henson, Hilding Neilson +1
The eclipsing binary epsilon Aur is unique in being a very long-period binary involving an evolved, variable F star and a suspected B main-sequence star enshrouded in an opaque cir…
The Magnetic Early B-type Stars IV: Breakout or Leakage? H emission as a diagnostic of plasma transport in centrifugal magnetospheres
M. E. Shultz, S. Owocki, Th. Rivinius +15
Rapidly rotating early-type stars with strong magnetic fields frequently show H emission originating in Centrifugal Magnetospheres (CMs), circumstellar structures in which centr…
Variability in Proto-Planetary Nebulae: VII. Light Curve Studies of Five Medium-bright, Oxygen-rich or Mixed-chemistry Post-AGB/Post-RGB Objects
Bruce J. Hrivnak, Gary Henson, Todd C. Hillwig +3
We have monitored over a ten-year interval the light variations of five evolved stars with very large mid-infrared excesses. All five objects appear to have oxygen-rich or mixed ox…
