Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1
A. Moór, P. Ábrahám, Á. Kóspál +23
Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…
SN2017jgh - A high-cadence complete shock cooling lightcurve of a SN IIb with the Kepler telescope
P. Armstrong, B. E. Tucker, A. Rest +69
SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of the Kepler/K2 mission. Here we present the Kepler/K2 and ground based observations of SN…
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…
Dipper-like variability of the Gaia alerted young star V555 Ori
Zsófia Nagy, Elza Szegedi-Elek, Péter Ábrahám +26
V555 Ori is a T Tauri star, whose 1.5 mag brightening was published as a Gaia science alert in 2017. We carried out optical and near-infrared photometric, and optical spectroscopic…
101 Trojans: a tale of period bimodality, binaries, and extremely slow rotators from K2 photometry
Csilla E. Kalup, László Molnár, Csaba Kiss +8
Various properties of Jovian trojan asteroids such as composition, rotation periods, and photometric amplitudes, or the rate of binarity in the population can provide information a…
The Peculiar Transient AT2018cow: A Possible Origin of A Type Ibn/IIn Supernova
Danfeng Xiang, Xiaofeng Wang, Weili Lin +47
We present our photometric and spectroscopic observations on the peculiar transient AT2018cow. The multi-band photometry covers from peak to 70 days and the spectroscopy rang…
