Electron-capture Supernova Candidates from Light Curves: Implications for Their Progenitors and Explosion Properties
Masato Sato, Nozomu Tominaga, Sergei I. Blinnikov +5
Core-collapse supernovae are explosions of massive stars. While most massive stars end as iron-core-collapse supernovae, less massive stars are expected to explode as electron-capt…
Physical Properties of Type II Supernovae Inferred from ZTF and ATLAS Photometric Data
Javier Silva-Farfán, Francisco Förster, Takashi J. Moriya +6
We report an analysis of a sample of 186 spectroscopically confirmed Type II supernova (SN) light curves (LCs) obtained from a combination of Zwicky Transient Facility (ZTF) and As…
The early discovery of SN 2017ahn: signatures of persistent interaction in a fast declining Type II supernova
L. Tartaglia, D. J. Sand, J. H. Groh +25
We present high-cadence, comprehensive data on the nearby () Type II SN 2017ahn, discovered within 1 day of explosion, from the very early phases after e…
Studying Type II supernovae as cosmological standard candles using the Dark Energy Survey
T. de Jaeger, L. Galbany, S. González-Gaitán +85
Despite vast improvements in the measurement of the cosmological parameters, the nature of dark energy and an accurate value of the Hubble constant (H) in the Hubble-Lemaître l…
Luminous Type II supernovae for their low expansion velocities
Ó. Rodríguez, G. Pignata, J. P. Anderson +27
We present optical and near-IR data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of earl…
The delay of shock breakout due to circumstellar material seen in most Type II Supernovae
F. Förster, T. J. Moriya, J. C. Maureira +35
Type II supernovae (SNe) originate from the explosion of hydrogen-rich supergiant massive stars. Their first electromagnetic signature is the shock breakout, a short-lived phenomen…
Continuum Foreground Polarization and Na~I Absorption in Type Ia SNe
P. Zelaya, A. Clocchiatti, D. Baade +9
We present a study of the continuum polarization over the 400--600 nm range of 19 Type Ia SNe obtained with FORS at the VLT. We separate them in those that show Na I D lines at the…
Defining Photometric Peculiar Type Ia Supernovae
S. Gonzalez-Gaitan, E. Y. Hsiao, G. Pignata +9
We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e. objects with light-curve characteristics such as later primary maxima and…
Supernova 2010as: the Lowest-Velocity Member of a Family of Flat-Velocity Type IIb Supernovae
Gastón Folatelli, Melina C. Bersten, Hanindyo Kuncarayakti +23
We present extensive optical and near-infrared photometric and spectroscopic observations of the stripped-envelope (SE) supernova SN 2010as. Spectroscopic peculiarities, such as in…
Characterizing the V-band light-curves of hydrogen-rich type II supernovae
Joseph P. Anderson, Santiago González-Gaitán, Mario Hamuy +26
We present an analysis of the diversity of V-band light-curves of hydrogen-rich type II supernovae. Analyzing a sample of 116 supernovae, several magnitude measurements are defined…
Persistent C II Absorption in the Normal Type Ia Supernova 2002fk
Régis Cartier, Mario Hamuy, Giuliano Pignata +16
We present well-sampled photometry of SN 2002fk starting 12 days before maximum light through 122 days after peak brightness, along with a series of 15 optical spectra f…
