A decade of radial-velocity monitoring of rho Leo: moment analysis and periodic variability
V. A. Checha, A. Aret, I. Kolka +6
We investigate the origin of long-term spectroscopic and photometric variability in the blue supergiant rho Leo, with particular emphasis on distinguishing between intrinsic pulsat…
X-rays from shock-heated gas in recurrent-nova remnants: Nested nova shells in a structured circumstellar medium
Sergio Martínez-González, Santiago Jiménez, Richard Wünsch +1
Recurrent symbiotic novae such as RS Oph show extended X-ray emission associated with the interaction of nova ejecta with the circumstellar environment. We investigate how repeated…
An Halpha survey of infrared bow-shocks around OB-type stars
Kuljeet Singh Saddal, Michaela Kraus, Dieter H. Nickeler +3
Bow shocks (BSs) around massive stars are commonly identified in mid-infrared (MIR) surveys. In contrast, systematic optical investigations of these structures remain scarce with o…
Dimming and pulsation shock of the coalesced star V838 Monocerotis
T. Kamiński, C. E. Woodward, T. Liimets +3
V838 Mon is the remnant of a stellar merger that occurred in 2002. Twenty-four years after the merger, the remnant closely resembles a red supergiant, but its luminosity is sustain…
Detection of a molecular hydrogen envelope around nova GK Persei
D. P. K. Banerjee, A. Evans, T. Liimets +4
The eruption of Nova Persei 1901 (GK Per) occurred 125 yrs ago; remarkably it still holds major surprises. Using data from the Spectro-Photometer for the History of the Universe, E…
