| Abstract | |
We present the detection and imaging of the spatially resolved shell of nova V382 Vel with SOAR adaptive optics module (SAM). The shell was observed in narrow-band filters H alpha and {[}O III] 5007 angstrom revealing different structures in each filter. The shell's angular diameter obtained was 9.9 arcsec, equivalent to 2.8 x 10(17) cm, using the distance of 1.79 kpc obtained by the Gaia mission. The upper limit for total shell mass derived from recombination lines is M-s = 1.4 x 10(-4) M-circle dot. Our photoionization models indicate an accretion disk with T-d = 60,000 K and L = 10(36) ergs as main ionizing source. (AU) | |
