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…
Constraining the Source of the High-velocity Ejecta in Type Ia SN 2019ein
C. Pellegrino, D. A. Howell, S. K. Sarbadhicary +16
We present multiwavelength photometric and spectroscopic observations of SN 2019ein, a high-velocity Type Ia supernova (SN Ia) discovered in the nearby galaxy NGC 5353 with a two-d…
ELT Contributions to The First Explosions
J. Craig Wheeler, József Vinkó, Rafaella Margutti +3
The large aperture and sensitive optical and near infrared imager spectrographs will enable an ELT system to observe some supernovae at large distances, deep into cosmological hist…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
Optical Observations of the Young Type Ic Supernova SN 2014L in M99
Jujia Zhang, Xiaofeng Wang, József Vinkó +22
We present optical spectroscopic and photometric observations of the nearby type Ic supernova (SN Ic) SN 2014L. This SN was discovered by the Tsinghua-NAOC Transient Survey (TNTS)…
Discovery of a satellite of the large trans-Neptunian object (225088) 2007OR10
Csaba Kiss, Gábor Marton, Anikó Farkas-Takács +6
2007OR10 is currently the third largest known dwarf planet in the transneptunian region, with an effective radiometric diameter of ~1535 km. It has a slow rotation period of ~45 h…
The Continuing Story of SN IIb 2013df: New Optical and IR Observations and Analysis
Tamás Szalai, József Vinkó, Andrea P. Nagy +17
SN 2013df is a nearby Type IIb supernova that seems to be the spectroscopic twin of the well-known SN 1993J. Previous studies revealed many, but not all interesting properties of t…
Comparative Analysis of SN 2012dn Optical Spectra: Days -14 to +114
J. T. Parrent, D. A. Howell, R. A. Fesen +19
SN 2012dn is a super-Chandrasekhar mass candidate in a purportedly normal spiral (SAcd) galaxy, and poses a challenge for theories of type Ia supernova diversity. Here we utilize t…
Pulsation and orbit of AU Pegasi
M. Jurkovic, L. Szabados, J. Vinkó +1
AU Pegasi is a pulsating star in a spectroscopic binary system with an orbital period of 53.26 days. Between 1960 and 1990 an extremely rapid period increase was observed in the va…
