On the progenitor system of V392 Persei

TL;DR

This paper investigates the progenitor system of V392 Persei using archival infrared data, suggesting it likely does not contain a luminous red giant but may have a lower luminosity donor, with similarities to GK Persei.

Contribution

It provides new insights into the nature of V392 Persei's donor star using archival infrared data and rules out a luminous red giant donor.

Findings

Unlikely to contain a luminous red giant donor

Possible presence of a lower luminosity red giant or sub-giant donor

Spectral energy distribution similar to GK Persei

Abstract

A discussion regarding the progenitor system of the nova and dwarf nova system V392 Persei using archival data from 2MASS and WISE. We find that the system is unlikely to contain a luminous red giant donor (i.e. a symbiotic system), but cannot exclude the presence of a lower luminosity red giant or a sub-giant donor. The similarity of the SED of the quiescent V392 Per to that of GK Persei is noted.
