The qWR star HD 45166. II. Fundamental stellar parameters and evidence of a latitude-dependent wind
J. H. Groh, A. S. Oliveira, J. E. Steiner
The enigmatic object HD 45166 is a qWR star in a binary system with an orbital period of 1.596 day, and presents a rich emission-line spectrum in addition to absorption lines from…
CAL 87 - an evolved wind-driven supersoft X-ray binary
A. S. Oliveira, J. E. Steiner
Compact binary supersoft X-ray sources (CBSS) are explained as being associated with hydrostatic nuclear burning on the surface of a white dwarf with high accretion rate. This high…
Transient jets in V617 Sagittarii
J. E. Steiner, A. S. Oliveira, C. A. O. Torres +1
Some of the luminous Compact Binary Supersoft X-Ray sources (CBSS) have shown indications of jets, also called satellites due to their appearance in the spectra. In V Sagittae (V S…
Assisted stellar suicide in V617 Sgr
J. E. Steiner, A. S. Oliveira, D. Cieslinski +1
V617 Sgr is a V Sagittae star - a group of binaries thought to be the galactic counterparts of the Compact Binary Supersoft X-ray Sources - CBSS. To check this hypothesis, we measu…
