Probing the Type Ia environment with Light Echoes
F. Patat
In general, Light Echoes (LE) are beautiful, rather academical and therefore unavoidably useless phenomena. In some cases, however, they can give interesting information about the…
Reflections on Reflexions: I. Light Echoes in Type Ia Supernovae
F. Patat
In the last ten years, observational evidences about a possible connection between Type Ia Supernovae (SNe) properties and the environment where they explode have been steadily gro…
Pre-Maximum Spectropolarimetry of the Type Ia SN 2004dt
Lifan Wang, Dietrich Baade, Peter Hoeflich +5
We report observations of SN 2004dt obtained with the Very Large Telescope of the European Southern Observatory on August 13.30, 2004 when the supernova was more than a week before…
Photometric Observations of the Type Ia SN 2002er in UGC 10743
G. Pignata, F. Patat, S. Benetti +20
Extensive light and colour curves for the Type Ia supernova SN 2002er are presented as part of the European Supernova Collaboration. We have collected UBVRI photometry from ten dif…
Metal abundances in extremely distant Galactic old open clusters. I. Berkeley 29 and Saurer 1
Giovanni Carraro, Fabio Bresolin, Sandro Villanova +3
We report on high resolution spectroscopy of four giant stars in the Galactic old open clusters Berkeley~29 and Saurer~1 obtained with HIRES at the Keck telescope. These two cluste…
ESC Observations of SN 2002er around Maximum Light
G. Pignata, F. Patat, R. Kotak +3
We present preliminary results of the observational campaign on SN 2002er carried out by the European Supernova Collaboration (ESC). For this supernova the optical coverage from ep…
