Low‐luminosity Type II supernovae: spectroscopic and photometric evolution
- A. Pastorello, L. Zampieri, +10 authors Marco Riello
- Physics
- 9 September 2003
In this paper we present spectroscopic and photometric observations for four core-collapsed supernovae (SNe), namely SNe 1994N, 1999br, 1999eu and 2001dc. Together with SN 1997D, we show that they… Expand
Cepheid calibration of Type Ia supernovae and the Hubble constant
- G. Altavilla, G. Fiorentino, +8 authors L. Zampieri
- Physics
- 14 January 2004
We investigate how a different calibration of the Cepheid period-luminosity (PL) relation, taking into account metallicity corrections, affects the absolute magnitude calibration of Type Ia… Expand
Photometry and Spectroscopy of the Type IIP SN 1999em from Outburst to Dust Formation
- A. Elmhamdi, I. J. Danziger, +7 authors M. Salvo
- Physics
- 1 February 2003
We present photometry and spectra of the Type IIP supernova 1999em in NGC 1637 from several days after the outburst till day 642. The radioactive tail of the recovered bolometric light curve of SN… Expand
Detection of Circumstellar Material in a Normal Type Ia Supernova
- F. Patat, P. Chandra, +19 authors M. Turatto
- Physics, Medicine
- Science
- 18 July 2007
Type Ia supernovae are important cosmological distance indicators. Each of these bright supernovae supposedly results from the thermonuclear explosion of a white dwarf star that, after accreting… Expand
A giant outburst two years before the core-collapse of a massive star
- A. Pastorello, S. Smartt, +32 authors L. Zampieri
- Physics, Medicine
- Nature
- 27 March 2007
The death of massive stars produces a variety of supernovae, which are linked to the structure of the exploding stars. The detection of several precursor stars of type II supernovae has been reported… Expand
High luminosity, slow ejecta and persistent carbon lines: SN 2009dc challenges thermonuclear explosion scenarios
- S. Taubenberger, S. Benetti, +22 authors W. Hillebrandt
- Physics
- 25 November 2010
Extended optical and near-IR observations reveal that SN 2009dc shares a number of similarities with normal Type Ia supernovae (SNe Ia), but is clearly overluminous, with a (pseudo-bolometric) peak… Expand
Supernova rates from the Southern inTermediate Redshift ESO Supernova Search (STRESS)
- M. T. Botticella, Marco Riello, +11 authors S. Taubenberger
- Physics
- 19 October 2007
Aims. To measure the supernova (SN) rates at intermediate redshift we performed the Southern inTermediate Redshift ESO Supernova Search (STRESS). Unlike most of the current high redshift SN searches,… Expand
SN 2005cs in M51 – II. Complete evolution in the optical and the near-infrared
- A. Pastorello, S. Valenti, +31 authors J. Wheeler
- Physics
- 14 January 2009
We present the results of the one-year long observational campaign of the type II plateau SN 2005cs, which exploded in the nearby spiral galaxy M51 (the Whirlpool galaxy). This extensive data set… Expand
A study of the Type II-P supernova 2003gd in M74
- M. Hendry, S. Smartt, +18 authors G. Pignata
- Physics
- 17 January 2005
We present photometric and spectroscopic data of the Type II-P supernova (SN II-P) 2003gd, which was discovered in M74 close to the end of its plateau phase. SN 2003gd is the first Type II supernova… Expand
Ultra-bright Optical Transients are Linked with Type Ic Supernovae
- A. Pastorello, S. Smartt, +56 authors US Naval Observatory - Flagstaff Station
- Physics
- 16 August 2010
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search and SCP-06F6 in a… Expand
