White Paper on MAAT@GTC
Francisco Prada, Robert Content, Ariel Goobar +41
MAAT is proposed as a visitor mirror-slicer optical system that will allow the OSIRIS spectrograph on the 10.4-m Gran telescopio CANARIAS (GTC) the capability to perform Integral F…
PISCO: The Pmas/ppak Integral-field Supernova hosts COmpilation
L. Galbany, J. P. Anderson, S. F. Sánchez +16
We present the Pmas/ppak Integral-field Supernova hosts COmpilation (PISCO) which comprises Integral Field Spectroscopy (IFS) of 232 supernova (SN) host galaxies, that hosted 272 S…
The puzzle of the CNO isotope ratios in AGB carbon stars
Carlos Abia, Rubén P. Hedrosa, Inma Domínguez +1
Previous determinations of the oxygen isotopic ratios in AGB carbon stars were at odds with the existing theoretical predictions. We aim to redetermine the oxygen ratios in these s…
Gamma-Ray emission from SN2014J near maximum optical light
J. Isern, P. Jean, E. Bravo +17
The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the t…
SN 2014J at M82: I. A middle-class type Ia supernova by all spectroscopic metrics
L. Galbany, M. E. Moreno-Raya, P. Ruiz-Lapuente +20
We present the intensive spectroscopic follow up of the type Ia supernova (SN Ia) 2014J in the starburst galaxy M82. Twenty-seven optical spectra have been acquired from January 22…
Type Ia Supernovae: Can Coriolis force break the symmetry of the gravitational confined detonation explosion mechanism?
D. García-Senz, R. M. Cabezón, I. Domínguez +1
Nowadays the number of models aimed at explaining the Type Ia supernova phenomenon is high and discriminating between them is a must-do. In this work we explore the influence of ro…
Observation of SN2011fe with INTEGRAL. I. Pre--maximum phase
J. Isern, P. Jean, E. Bravo +19
SN2011fe was detected by the Palomar Transient Factory on August 24th 2011 in M101 a few hours after the explosion. From the early optical spectra it was immediately realized that…
The First Fluorine Abundance Determinations in Extragalactic AGB Carbon Stars
C. Abia, K. Cunha, S. Cristallo +5
Fluorine (19F) abundances (or upper limits) are derived in six extragalactic AGB carbon stars from the HF(1-0) R9 line at 2.3358 mu in high resolution spectra. The stars belong to…
Incomplete carbon-oxygen detonation in Type Ia supernovae
Inma Domínguez, Alexei Khokhlov
Incomplete carbon-oxygen detonation with reactions terminating after burning of 12C in the leading 12C + 12C reaction (C-detonation) may occur in the low density outer layers of wh…
The impact of chemical differentiation of white dwarfs on thermonuclear supernovae
Eduardo Bravo, Leandro G. Althaus, Enrique García-Berro +1
Gravitational settling of 22Ne in cooling white dwarfs can affect the outcome of thermonuclear supernovae. We investigate how the supernova energetics and nucleosynthesis are in tu…
Type Ia Supernovae: Influence of the Progenitor on the Explosion
Inma Domínguez, Peter Höflich, Oscar Straniero Craig Wheeler +1
The influence of the initial composition and structure of the exploding white dwarf on the nucleosynthesis and structure of Type Ia Supernovae has been studied. The progenitor stru…
