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…
A study of the photometric and spectroscopic variations of the prototypical FU Orionis-type star V1057 Cyg
Zs. M. Szabó, Á. Kóspál, P. Ábrahám +19
Among the low-mass pre-main sequence stars, a small group called FU Orionis-type objects (FUors) are notable for undergoing powerful accretion outbursts. V1057 Cyg, a classical exa…
Absolute Distances to Nearby Type Ia Supernovae via Light Curve Fitting Methods
J. Vinkó, A. Ordasi, T. Szalai +22
We present a comparative study of absolute distances to a sample of very nearby, bright Type Ia supernovae (SNe) derived from high cadence, high signal-to-noise, multi-band photome…
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…
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…
Multi-wavelength study of the low-luminosity outbursting young star HBC 722
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +22
HBC 722 (V2493 Cyg) is a young eruptive star in outburst since 2010. It is an FU Orionis-type object with an atypically low outburst luminosity. Because it was well characterized i…
