The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset
I. Mäntynen, E. Kankare, S. Mattila +7
Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…
V5852 Sgr: An Unusual Nova Possibly Associated with the Sagittarius Stream
E. Aydi, P. Mróz, P. A. Whitelock +16
We report spectroscopic and photometric follow-up of the peculiar nova V5852~Sgr (discovered as OGLE-2015-NOVA-01), which exhibits a combination of features from different nova cla…
Properties of the solar neighbor WISE J072003.20-084651.2
V. D. Ivanov, P. Vaisanen, A. Y. Kniazev +14
The severe crowding towards the Galactic plane suggests that the census of nearby stars in that direction may be incomplete. Recently, Scholz reported a new M9 object at an estimat…
SN 2005at - A neglected type Ic supernova at 10 Mpc
E. Kankare, M. Fraser, S. Ryder +7
We present a photometric and spectroscopic study of a reddened type Ic supernova (SN) 2005at. We report our results based on the available data of SN 2005at, including late-time ob…
The nature of supernovae 2010O and 2010P in Arp 299 - I. Near-infrared and optical evolution
E. Kankare, S. Mattila, S. Ryder +10
We present near-infrared and optical photometry, plus optical spectroscopy of two stripped-envelope supernovae (SNe) 2010O and 2010P that exploded in two different components of an…
Abell 48 - a rare WN-type central star of a planetary nebula
H. Todt, A. Y. Kniazev, V. V. Gvaramadze +18
A considerable fraction of the central stars of planetary nebulae (CSPNe) are hydrogen-deficient. Almost all of these H-deficient central stars (CSs) display spectra with strong ca…
