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…
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…
Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…
Newborn jet in the symbiotic system R Aquarii
T. Liimets, D. P. K. Banerjee, M. Santander-García +12
R Aquarii (R Aqr) is a well-known symbiotic binary that has attracted renewed interest during its recent periastron passage, an event that occurs only once every about 40 years. Th…
