3D MHD models of the centrifugal magnetosphere from a massive star with an oblique dipole field
Asif ud-Doula, Stanley P. Owocki, Christopher Russell +2
We present results from new self-consistent 3D MHD simulations of the magnetospheres from massive stars with a dipole magnetic axis that has a non-zero obliquity angle () to the…
Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…
Eta Carinae: an evolving view of the central binary, its interacting winds and its foreground ejecta
Theodore R. Gull, D. John Hillier, Henrik Hartman +13
FUV spectra of Eta Car, recorded across two decades with HST/STIS, document multiple changes in resonant lines caused by dissipating extinction in our line of sight. The FUV flux h…
Conditions in the WR 140 wind-collision region revealed by the 1.083-micron He I line profile
Peredur M. Williams, Watson P. Varricatt, André-Nicolas Chené +10
We present spectroscopy of the P~Cygni profile of the 1.083-micron He I line in the WC7 + O5 colliding-wind binary (CWB) WR 140 (HD 193793), observed in 2008, before its periastron…
The VVV Infrared Variability Catalog (VIVA-I)
C. E. Ferreira Lopes, N. J. G. Cross, M. Catelan +17
Thanks to the VISTA Variables in the Via Lactea (VVV) ESO Public Survey it is now possible to explore a large number of objects in those regions. This paper addresses the variabili…
The variability of the BRITE-est Wolf-Rayet binary, Velorum I. Photometric and spectroscopic evidence for colliding winds
Noel D. Richardson, Christopher M. P. Russell, Lucas St-Jean +26
We report on the first multi-color precision light curve of the bright Wolf-Rayet binary Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation…
