TIC 219006972: A Compact, Coplanar Quadruple Star System Consisting of Two Eclipsing Binaries with an Outer Period of 168 days
Veselin B. Kostov, Tamas Borkovits, Saul A. Rappaport +12
We present the discovery of a new highly compact quadruple star system, TIC 219006972, consisting of two eclipsing binary stars with orbital periods of 8.3 days and 13.7 days, and…
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…
A multi-epoch, multi-wavelength study of the classical FUor V1515 Cyg approaching quiescence
Zs. M. Szabó, Á. Kóspál, P. Ábrahám +28
Historically, FU Orionis-type stars are low-mass, pre-main sequence stars. The members of this class experience powerful accretion outbursts and remain in an enhanced accretion sta…
Accretion variability of the multiple T Tauri system VW Cha
Gabriella Zsidi, Eleonora Fiorellino, Ágnes Kóspál +5
Classical T Tauri stars are low-mass objects, which are still accreting material from the surrounding circumstellar disk. The accretion process is essential in the formation of Sun…
First results on RR Lyrae stars with the TESS space telescope: untangling the connections between mode content, colors and distances
László Molnár, Attila Bódi, András Pál +25
The TESS space telescope is collecting continuous, high-precision optical photometry of stars throughout the sky, including thousands of RR Lyrae stars. In this paper, we present r…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
