ExoClock Project IV: A homogeneous catalogue of 620 updated exoplanet ephemerides
A. Kokori, A. Tsiaras, G. Pantelidou +323
The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space and ground based telescopes. This study presents an updated catalogue o…
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…
V838 Mon: A slow waking up of Sleeping Beauty?
T. Liimets, I. Kolka, M. Kraus +15
Context. V838 Monocerotis is a peculiar binary that underwent an immense stellar explosion in 2002, leaving behind an expanding cool supergiant and a hot B3V companion. Five years…
ExoClock Project III: 450 new exoplanet ephemerides from ground and space observations
A. Kokori, A. Tsiaras, B. Edwards +214
The ExoClock project has been created with the aim of increasing the efficiency of the Ariel mission. It will achieve this by continuously monitoring and updating the ephemerides o…
V392 Persei: a γ-ray bright nova eruption from a known dwarf nova
F. J. Murphy-Glaysher, M. J. Darnley, É. J. Harvey +57
V392 Persei is a known dwarf nova (DN) that underwent a classical nova eruption in 2018. Here we report ground-based optical, Swift UV and X-ray, and Fermi-LAT γ-ray observations f…
Variability survey of brightest stars in selected OB associations
Jaan Laur, Indrek Kolka, Tõnis Eenmäe +2
The stellar evolution theory of massive stars remains uncalibrated with high-precision photometric observational data mainly due to a small number of luminous stars that are monito…
