A possible detected faint shell of the classical Nova QZ Aurigae

Abstract

We observed the faint shell of QZ Aur (Nova Aurigae 1964) nearly 30 years of its outburst. Despite a diameter of 0.55(+0.12)(-0,16) arcsec of the intrinsic point source of QZ Aur, a narrow-band Ha image shows that the diameter of the nova shell in 1995 was 0.86(+0.14)(-0.11) arcsec. This rather faint shell exists for a nova suggests that QZ Aur is an object worthy of further study.
