New ACV variables discovered in the Zwicky Transient Facility survey
B. Bauer-Fasching, K. Bernhard, E. Brändli +8
The manifestation of surface spots on magnetic chemically peculiar (mCP) stars is most commonly explained by the atomic diffusion theory, which requires a calm stellar atmosphere a…
A New Approach to Find the Böhm-Vitense gap
Tahereh Ramezani, Ernst Paunzen, Martin Piecka +1
This paper discusses the B{ö}hm-Vitense gap, a gap in the colours of stars that occurs when the atmosphere changes from radiative to convective in deep layers. We are using differe…
Science with a small two-band UV-photometry mission II: Observations of stars and stellar systems
J. Krtička, J. Benáček, J. Budaj +32
We outline the impact of a small two-band UV-photometry satellite mission on the field of stellar physics, magnetospheres of stars, binaries, stellar clusters, interstellar matter,…
Structure of Open Clusters -- Gaia DR2 and its limitations
Martin Piecka, Ernst Paunzen
Very precise observational data are needed for studying the stellar cluster parameters (distance, reddening, age, metallicity) and cluster internal kinematics. In turn, these give…
Aggregates of clusters in the Gaia data
M. Piecka, E. Paunzen
The precision of the parallax measurements by Gaia is unprecedented. As of Gaia Data Release 2, the number of known nearby open clusters has increased. Some of the clusters appear…
White dwarf-open cluster associations based on Gaia DR2
M. Prišegen, M. Piecka, N. Faltová +2
Fundamental parameters and physical processes leading to the formation of white dwarfs (WDs) may be constrained and refined by discovering WDs in open clusters (OCs). Cluster membe…
