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…
Detectability of deuterium in spectra of early-type stars
Veronika Mitrokhina, Colin P. Folsom, Mihkel Kama +1
Context: Deuterium is easily destroyed in stellar interiors through nuclear fusion. It is therefore usually not expected to be present in stellar photospheres. Early-type stars, wi…
Ariel stellar characterisation IV. Fundamental parameters of 18 hot stars in the Ariel mission candidate sample
H. Ramler, S. P. D. Borthakur, C. P. Folsom +16
The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically signific…
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…
Atmospheric dynamics of the hypergiant RW Cep during the Great Dimming
A. Kasikov, I. Kolka, A. Aret +5
The hypergiant RW Cep is one of the largest stars in our galaxy. The evolution and mass loss of such stars has profound effects on their surrounding regions and the galaxy as a who…
