Supernovae are magnificent phenomena in the night sky and have always been a wonder for human beings. A supernova is a stellar explosion that emits a burst of radiation that results in an extremely bright object that can darken its entire host galaxy before disappearing for several weeks or months. A class of supernovae, known as type Ia Supernovae (SN Ia), is characterized by the absence of hydrogen emission lines in the spectra and by the presence of a Si II silicon absorption line prominent near the maximum light (1). With uniform light curves and spectral evolution, SN Ia have been increasingly used as reliable distance indicators in the measurement of imposing cosmological impulses (2). This use has led to the need for a more intense study of the nature of SN Ia.
Poiché non esiste ancora un candidato migliore di quello che sono in accordo con tutti i criteri teorici di osservazione, l'identificazione dei sistemi progenitori di SN Ia rimane difficile.
