EI Eridani: a star under the influence -- The effect of magnetic activity in the short and long term
L. Kriskovics, Zs. Kővári, B. Seli +5
We use our photometric time series of more than forty years to analyze the long-term behaviour of EI Eri. Flare activity is investigated using space-borne photometric data obtained…
Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS
Á. Boldog, Gy. M. Szabó, L. Kriskovics +76
DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend…
Photometric and spectroscopic study of the burst-like brightening of two Gaia-alerted young stellar objects
Zsófia Nagy, Péter Ábrahám, Ágnes Kóspál +18
Young stars show variability on different time-scales from hours to decades, with a range of amplitudes. We studied two young stars, which triggered the Gaia Science Alerts system…
Recurrent strong outbursts of an EXor-like young eruptive star Gaia20eae
Fernando Cruz-Sáenz de Miera, Ágnes Kóspál, Péter Ábrahám +21
We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020 after showing a 3…
A low-luminosity core-collapse supernova very similar to SN 2005cs
Zoltán Jäger, József Vinkó, Barna I. Bíró +5
We present observations and analysis of PSN J17292918+7542390, a low-luminosity Type II-P supernova (LL SN IIP). The observed sample of such events is still low, and their nature i…
Time-series Doppler images and surface differential rotation of the effectively-single rapidly-rotating K-giant KU Pegasi
Zs. Kővári, A. Künstler, K. G. Strassmeier +6
According to most stellar dynamo theories, differential rotation (DR) plays a crucial role for the generation of toroidal magnetic fields. Numerical models predict surface differen…
