Description
Following our tentative discovery of a faint shell around V1315 Aql
reported in Sahman et al., we undertook deep Hα imaging and
intermediate-resolution spectroscopy of the shell. We find that the
shell has its geometric centre located on V1315 Aql. The mass, spectral
features, and density of the shell are consistent with other nova
shells, rather than planetary nebulae or supernova remnants. The radial
velocity of the shell is consistent with the systemic velocity of V1315
Aql. We believe this evidence strongly suggests that the shell
originates from an earlier nova event. This is the first nova shell
discovered around a nova-like and supports the theory of nova-induced
cycles in mass transfer rates (hibernation theory) first proposed by
Shara et al.

Binary Stars
The study of binary stars is essential to stellar astrophysics. A large number of stars form and evolve within binary systems. Therefore, their study is fundamental to understand stellar and galactic evolution. Particularly relevant is that binary systems are still the best source of precise stellar mass and radius measurements. Research lines
