No surviving companion in Kepler's supernova
Pilar Ruiz-Lapuente, Francesco Damiani, Luigi R. Bedin +5
We have surveyed Kepler's supernova remnant in search of the companion star of the explosion. We have gone as deep as 2.6 solar luminosities in the stars within 20% of the radius o…
Origin of Galactic Type-Ia supernovae: SN 1572 and SN 1006
J. I. González Hernández, P. Ruiz-Lapuente, H. M. Tabernero +4
We have been searching for surviving companions of progenitors of Galactic Type-Ia supernovae, in particular SN 1572 and SN 1006. These companion stars are expected to show peculia…
No surviving evolved companions to the progenitor of supernova SN 1006
Jonay I. Gonzalez Hernandez, Pilar Ruiz-Lapuente, Hugo M. Tabernero +4
Type Ia supernovae are thought to occur as a white dwarf made of carbon and oxygen accretes sufficient mass to trigger a thermonuclear explosion. The accretion could occur sl…
Optical and IR observations of SN 2002dj: some possible common properties of fast expanding SNe Ia
G. Pignata, S. Benetti, P. A. Mazzali +17
As part of the European Supernova Collaboration we obtained extensive photometry and spectroscopy of the type Ia SN 2002dj covering epochs from 11 days before to nearly two years a…
Improved Cosmological Constraints from New, Old and Combined Supernova Datasets
M. Kowalski, D. Rubin, G. Aldering +67
We present a new compilation of Type Ia supernovae (SNe Ia), a new dataset of low-redshift nearby-Hubble-flow SNe and new analysis procedures to work with these heterogeneous compi…
Light curves of five type Ia supernovae at intermediate redshift
R. Amanullah, V. Stanishev, A. Goobar +14
We present multi-band light curves and distances for five type Ia supernovae at intermediate redshifts, 0.18<z<0.27. Three telescopes on the Canary Island of La Palma, INT, NOT and…
