An UXor among FUors: extinction related brightness variations of the young eruptive star V582 Aur
P. Ábrahám, Á. Kóspál, M. Kun +24
V582 Aur is an FU Ori-type young eruptive star in outburst since 1985. The eruption is currently in a relatively constant plateau phase, with photometric and spectroscopic va…
Rotation--differential rotation relationships for late-type single and binary stars from Doppler imaging
Zs. Kővári, K. Oláh, L. Kriskovics +3
From our sample of spotted late-type stars showing surface differential rotation we find that the relationship between the rotation period and the surface shear coefficient $α=ΔΩ/Ω…
Antisolar differential rotation with surface lithium enrichment on the single K-giant V1192 Orionis
Zs. Kővári, K. G. Strassmeier, T. A. Carroll +7
Context: Stars with about 12 solar masses at the red giant branch (RGB) represent an intriguing period of stellar evolution, i.e. when the convective envelope interacts with the…
Frequent flaring in the TRAPPIST-1 system - unsuited for life?
Krisztián Vida, Zsolt Kővári, András Pál +2
We analyze short cadence K2 light curve of the TRAPPIST-1 system. Fourier analysis of the data suggests days. The light curve shows several flares, o…
Photometric and radial-velocity time-series of RR Lyrae stars in M3: analysis of single-mode variables
J. Jurcsik, P. Smitola, G. Hajdu +18
We present the first simultaneous photometric and spectroscopic investigation of a large set of RR Lyrae variables in a globular cluster. The radial-velocity data presented compris…
