TCP J072226836220548: a new AM CVn type system with infrequent outbursts
Alexander Tarasenkov, Kirill Sokolovsky, Alexandr Dodin +11
We present the discovery of TCP J072226836220548, a new ultracompact binary system of the AM CVn type. This system was first identified displaying a mag outburst on 2…
PNV J00444033+4113068: early superhumps with 0.7 mag amplitude and non-red color
Yusuke Tampo, Keisuke Isogai, Naoto Kojiguchi +13
In the first days of WZ Sge-type dwarf nova (DN) outbursts, the 2:1 resonance induces a spiral arm structure in the accretion disk, which is observed as early superhumps in optical…
Morpho-kinematic modeling of the expanding ejecta of the extremely slow nova V1280 Scorpii
Hiroyuki Naito, Akito Tajitsu, Valèrio A. R. M. Ribeiro +10
Morphology of nova ejecta is essential for fully understanding the physical processes involved in nova eruptions. We studied the 3D morphology of the expanding ejecta of the extrem…
Spectroscopic Observations of V455 Andromedae Superoutburst in 2007: the Most Exotic Spectral Features in Dwarf Nova Outbursts
Yusuke Tampo, Daisaku Nogami, Taichi Kato +10
We present our spectroscopic observations of V455 Andromedae during the 2007 superoutburst. Our observations cover this superoutburst from around the optical peak of the outburst t…
Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle
A. Pastorello, C. S. Kochanek, M. Fraser +52
Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like events are characterized by a long-lasting phase of erratic variability which ends with two lumi…
M31N 2008-12a - the remarkable recurrent nova in M31: Pan-chromatic observations of the 2015 eruption
M. J. Darnley, M. Henze, M. F. Bode +52
The Andromeda Galaxy recurrent nova M31N 2008-12a had been observed in eruption ten times, including yearly eruptions from 2008-2014. With a measured recurrence period of $P_\mathr…
