iPTF15eqv: Multi-wavelength Expos\'e of a Peculiar Calcium-rich Transient
Dan Milisavljevic,D. Patnaude,John C. Raymond,Maria R. Drout,R. Margutti,Atish Kamble,R. Chornock,James Guillochon,Nathan Edward Sanders,J. T. Parrent,Lorenzo Lovisari,Igor Chilingarian,P. Challis,R. P. Kirshner,Matthew T. Penny,Koichi Itagaki,John J. Eldridge,Takashi J. Moriya +17 more
TL;DR: In this paper, the authors presented multi-wavelength observations of iPTF15eqv in NGC 3430, which exhibits a unique combination of properties that bridge those observed in Ca-rich transients and Type Ib/c supernovae.
Journal ArticleDOI
Superluminous Transients at AGN Centers from Interaction between Black Hole Disk Winds and Broad-line Region Clouds
TL;DR: In this article, superluminous transients that appear at central regions of active galactic nuclei (AGNs) such as CSS100217:102913+404220 (CSS100217) and PS16dtm, which reach near or super-Eddington luminosities of the central black holes, are powered by the interaction between accretion-disk winds and clouds in broad-line regions surrounding them.
Journal ArticleDOI
SN?2009js at the Crossroads between Normal and Subluminous Type?IIP Supernovae: Optical and Mid-infrared Evolution
Poshak Gandhi,Poshak Gandhi,Masayuki Yamanaka,Masayuki Yamanaka,Masaomi Tanaka,Takaya Nozawa,Koji S. Kawabata,Ivo Saviane,Keiichi Maeda,Takashi J. Moriya,Takashi J. Moriya,Takashi Hattori,Mahito Sasada,Ryosuke Itoh +13 more
TL;DR: In this paper, the authors present a study of SN?2009js in NGC?918, which is the first subluminous SN?IIP to be studied in the mid-infrared.
Journal ArticleDOI
Mass loss of massive stars near the Eddington luminosity by core neutrino emission shortly before their explosion
TL;DR: In this article, the authors proposed a novel mechanism for enhancing the mass-loss rates of massive stars shortly before their explosion, which can be activated in Wolf-Rayet stars and create the hydrogen-poor, as well as hydrogen-rich, dense circumstellar media observed in some supernovae.

TL;DR: In this article, the authors present six indicators of electron-capture supernovae and show that supernova 2018zd is the only known supernova having strong evidence for or consistent with all six: progenitor identification, circumstellar material, chemical composition, explosion energy, light curve, and nucleosynthesis.
