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…
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…
SN 2018zd: An Unusual Stellar Explosion as Part of the Diverse Type II Supernova Landscape
Jujia Zhang, Xiaofeng Wang, Jozsef Vinko +29
We present extensive observations of SN 2018zd covering the first \,d after the explosion. This SN shows a possible shock-breakout signal \,hr after the explosion…
Constraints on the physical properties of Type Ia supernovae from photometry
R. Konyves-Toth, J. Vinko, A. Ordasi +17
We present a photometric study of 17 Type Ia supernovae (SNe) based on multi-color (Bessell BVRI) data taken at Piszkesteto mountain station of Konkoly Observatory, Hungary between…
The Type II-P Supernova 2017eaw: from explosion to the nebular phase
Tamás Szalai, József Vinkó, Réka Könyves-Tóth +36
The nearby SN 2017eaw is a Type II-P (``plateau') supernova showing early-time, moderate CSM interaction. We present a comprehensive study of this SN including the analysis of high…
K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
