A need to revise stellar opacities from asteroseismology of Scuti stars

Jadwiga Daszyńska-Daszkiewicz, Przemysław Walczak, Alexey Pamyatnykh +2

We construct seismic models of the four double-mode radial Scuti stars adopting opacities from three databases: OPAL, OP and OPLIB. The aim is to find the models that fit the o…

Iterative construction of the optimal sunspot number series

Michal Švanda, Martina Pavelková, Jiří Dvořák +1

The relative number of sunspots represents the longest evidence describing the level of solar activity. As such, its use goes beyond solar physics, e.g. towards climate research. T…

Searching for compact objects in the single-lined spectroscopic binaries of the young Galactic cluster NGC 6231

G. Banyard, L. Mahy, H. Sana +7

Recent evolutionary computations predict that a few percent of massive OB stars in binary systems should have a dormant BH companion. Despite several reported X-ray quiet OB+BH sys…

Dark off-limb gap: manifestation of temperature minimum and dynamic nature of the chromosphere

D. Kuridze, P. Heinzel, J. Koza +1

We study off-limb emission of the lower solar atmosphere using high-resolution imaging spectroscopy in the H and Ca II 8542 Å lines obtained with the CHROMospheric Imaging Spect…

TIC 114936199: A Quadruple Star System with a 12-day Outer Orbit Eclipse

Brian P. Powell, Saul A. Rappaport, Tamás Borkovits +19

We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing b…

Wolf-Rayet stars: recent advances and persisting problems

Tomer Shenar

Wolf-Rayet (WR) stars comprise a class of stars whose spectra are dominated by strong, broad emission lines that are associated with copious mass loss. In the massive-star regime,…

The European Solar Telescope

C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14

The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…

Starspots Modelling and Flare Analysis on Selected MV Stars

Kamil Bicz, Robert Falewicz, Małgorzata Pietras +2

We studied light curves of GJ 1243, YZ CMi, and V374 Peg, observed by TESS for the presence of stellar spots and stellar flares. One of the main goals was to model light curves of…

Gaia Data Release 3: Properties of the line broadening parameter derived with the Radial Velocity Spectrometer (RVS)

Y. Frémat, F. Royer, O. Marchal +38

The third release of the Gaia catalogue contains the radial velocities for 33,812,183 stars having effective temperatures ranging from 3100 K to 14,500 K. The measurements are base…

Narrowband spikes observed during the 13 June 2012 flare in the 800-2000 MHz range

M. Karlicky, J. Rybak, J. Benacek +1

Narrowband (~5 MHz) and short-lived (~0.01 s) spikes with three different distributions on the 800-2000 MHz radio spectrum of the 13 June 2012 flare are detected and analyzed. We d…

HD 183986: a high-contrast SB2 system with a pulsating component

Martin Vaňko, Theodor Pribulla, Pavol Gajdoš +7

There is a small group of peculiar early-type stars on the main sequence that show different rotation velocities from different spectral lines. This inconsistency might be due to t…
