Will post-nova V1315 Aql enter into hibernation?

FANG X. and QIAN S.

Abstract (from CDS):

In a hibernation scenario, systems after a nova outburst will exhibit high mass-transfer rates and change themselves into nova-like variables. The disc winds from the high-state disc bring away extra mass and angular momentum that affect evolution. Assuming the evolution is stable, we calculated the mass-transfer rate {dot}M₂ and the effective mass-radius index ζ of the donor stars for nova-likes with respect to the mass-loss proportion α based on their secular orbital period variations, and we located their positions on the τ_{{dot}€ M₂_/ τ_KH_-ζdiagram, where τ_{dot}_M₂_and tau_KH_are the mass–transfer and thermal time–scales, respectively. V1315 Aql, a nova–like star surrounded by a nova shell due to a nova eruption 500–1200 yr earlier, is an exemplar for the hibernation hypothesis. However, in comparison with other nova–likes, we found that the mass transfer in V1315 Aql is unstable, due to irradiation by the white dwarf and accretion, and we estimated its magnitude–decline rate as ∼10^–4^mag yr^–1^, which is consistent with long–term optical observations. Its time–scale of magnitude decline is comparable to the recurrence time–scale of nova eruption, which indicates that V1315 Aql will not enter into hibernation. This conclusion seems to confirm the prediction of Hillman et al. that a post–nova with orbital period >3 h will never hibernate deeply.}
