TL;DR: In this article, the authors report the results of a three-year-long dedicated monitoring campaign of a restless luminous blue variable (LBV) in NGC 7259, and construct bolometric light curves and measure the total luminosities of these eruptive or explosive events.
Journal ArticleDOI

Melina C. Bersten,Omar Gustavo Benvenuto,Ken'ichi Nomoto,Mattias Ergon,Gastón Folatelli,Jesper Sollerman,Stefano Benetti,Maria Teresa Botticella,Morgan Fraser,Rubina Kotak,Keiichi Maeda,P. Ochner,L. Tomasella +12 more
TL;DR: In this article, a set of hydrodynamical models based on stellar evolutionary progenitors is used to study the nature of SN 2011dh, and it is shown that a large progenitor star with R {approx} 200 R{sub Sun }-is needed to reproduce the early light curve (LC) of SN2011dh.
Journal ArticleDOI
The first month of evolution of the slow-rising Type IIP SN 2013ej in M74

TL;DR: In this article, early photometric and spectroscopic observations of SN 2013ej, a bright type IIP supernova in M74.14 UT, were presented, with the earliest detection of this explosion occurring on 2013 July 24 and the spectroscopy monitoring began on July 27.
Journal ArticleDOI

TL;DR: In this paper, the authors present optical and near-infrared (NIR) photometry and spectroscopy of the Type IIb supernova 2011dh for the first 100 days.
