V1315 Aquilae is a cataclysmic variable star in the north of the equatorial constellationofAquila. It is in the sub-set of nova-like (NL) variables,^[5] specifically a SW Sextantis star (a type of white dwarf-donor star pair).^[6]^[7] These were characterized as having non-magnetic white dwarfs – thus that do not undergo dwarf-nova bright luminations ("eruptions").^[5] There is countering evidence for some magnetism.^[8]^[9] Being a SW Sextantis star, V1315 Aquilae has a high rate of mass transfer, so it is in steady-state accretion and in a constant state of outburst.^[10] It emits most of its light in the visible range, and this comes from the accretion disk.^[10] The eclipse depth is 1.8 mag.^[11] No description of the donor star is made.

Nova shell

[edit]

V1315 Aquilae has a roughly spherical shell of material around it with a maximal 1×10⁻⁵ solar masses (1⁄10000 M_☉), which is too small to be any starburst nebula or more advanced supernova remnant. It is consistent with models of a remnant of a nova-scale eruption roughly 500 to 1200 years old (that is, plus the time for the light from this system to travel to the Earth). V1315 Aquilae is the first nova-like system to have been discovered with a nova shell.^[5]
