Direct evidence of two-component ejecta in supernova 2016gkg from nebular spectroscopy

Hanindyo Kuncarayakti, Gaston Folatelli, Keiichi Maeda +17

Spectral observations of the type-IIb supernova (SN) 2016gkg at 300-800 days are reported. The spectra show nebular characteristics, revealing emission from the progenitor star's m…

Properties of the post in-spiral common envelope ejecta II: dust formation

Roberto Iaconi, Keiichi Maeda, Takaya Nozawa +2

We study the formation of dust in the expanding gas ejected as a result of a common envelope binary interaction. In our novel approach, we apply the dust formation model of Nozawa…

Supernova 2014C: ongoing interaction with extended circumstellar material with silicate dust

Samaporn Tinyanont, Ryan M Lau, Mansi M Kasliwal +8

Supernova (SN) 2014C is a unique explosion where a seemingly typical hydrogen-poor stripped envelope SN started to interact with a dense, hydrogen-rich circumstellar medium (CSM) a…

Properties of the post in-spiral common envelope ejecta I: dynamical and thermal evolution

Roberto Iaconi, Keiichi Maeda, Orsola De Marco +2

We investigate the common envelope binary interaction, that leads to the formation of compact binaries, such as the progenitor of Type Ia supernovae or of mergers that emit detecta…

OISTER Optical and Near-Infrared Observations of the Super-Chandrasekhar Supernova Candidate SN 2012dn: Dust Emission from the Circumstellar Shell

Masayuki Yamanaka, Keiichi Maeda, Masaomi Tanaka +34

We present extensively dense observations of the super-Chandrasekhar supernova (SC SN) candidate SN 2012dn from to days after the date of its -band maximum in the o…

Disappearance of the Progenitor of Supernova iPTF13bvn

Gastón Folatelli, Schuyler D. Van Dyk, Hanindyo Kuncarayakti +13

Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor candidate in pre-explosion images. We performed deep ultraviolet…
