Imaging and Analysis of Neon Nova V382 Vel Shell
Publications of the Astronomical Society of the Pacific(2019)
摘要
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.
