The Carnegie Supernova Project I photometry data release of low-redshift stripped envelope supernovae
(EDP Sciences, 2018)
The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and ...
SN 2012fr: ultraviolet, optical, and near-infrared light curves of a type Ia supernova observed within a day of explosion
(The American Astronomical Society, 2018-05-20)
We present detailed ultraviolet, optical, and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise high-cadence light curves provide a dense ...
Carnegie supernova project-II: Extending the near-infrared hubble diagram for type ia supernovae to z∼0.1 ∗
(Institute of Physics Publishing, 2019)
© 2018. The Astronomical Society of the Pacific. All rights reserved. Printed in the U.S.A.The Carnegie Supernova Project-II (CSP-II) was an NSF-funded, four-year program to obtain optical and near-infrared observations ...
Super-luminous type II supernovae powered by magnetars
(EDP Sciences, 2018-05-15)
Magnetar power is believed to be at the origin of numerous super-luminous supernovae (SNe) of Type Ic, arising from compact, hydrogen-deficient, Wolf-Rayet type stars. Here, we investigate the properties that magnetar power ...
Type IIP supernova light curves affected by the acceleration of red supergiant winds
(Oxford University Press, 2018)
We introduce the first synthetic light-curve model set of Type IIP supernovae exploded within circumstellar media in which the acceleration of the red supergiant winds is taken into account. Because wind acceleration makes ...
A magnetar model for the hydrogen rich super luminous supernova iPTF14hls
(EDP Sciences, 2018)
Transient surveys have recently revealed the existence of H-rich super-luminous supernovae (SLSN; e. g., iPTF14hls, OGLE-SN14-073) that are characterized by an exceptionally high time-integrated bolometric luminosity, a ...
Observed type II supernova colours from the carnegie supernova project-I
(Oxford University Press, 2018-06)
We present a study of observed Type II supernova (SN II) colours using optical/near-infrared photometric data from the Carnegie Supernovae Project-I. We analyse four colours (B - V, u - g, g - r, and g - Y) and find that ...
Analysis of blueshifted emission peaks in Type II supernovae
(Royal Astronomical Society, 2014-06-11)
In classical P-Cygni profiles, theory predicts emission to peak at zero rest velocity. However,
supernova spectra exhibit emission that is generally blueshifted. While this characteristic
has been reported in many SNe, ...
Supernovae from massive stars with extended tenuous envelopes
(EDP Sciences S A, 2018)
Massive stars with a core-halo structure are interesting objects for stellar physics and hydrodynamics. Using simulations for stellar evolution, radiation hydrodynamics, and radiative transfer, we study the explosion of ...
A Type II Supernova Hubble Diagram from the CSP-I, SDSS-II, and SNLS Surveys
(Institute of Physics Publishing, 2017)
The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude. Such numbers will restrict spectroscopic follow-up in the vast majority of cases, and hence new ...
