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…
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…
Yellow hypergiant V509 Cas -- stable in the 'yellow void'
A. Kasikov, I. Kolka, A. Aret +2
The yellow hypergiant star V509 Cas is currently undergoing an extreme phase of evolution. Having experienced eruptive mass-loss outbursts in the 20th century, the star's effective…
A rare phosphorus-rich star in an eclipsing binary from TESS
Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6
Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…
