An A&A preprint on ArXiv today, “Evolution of the recent high-accretion state of the recurrent nova T CrB“, reviews multi-wavelength observations of the recent super-active state and subsequent 2023+ faint state in the context of changes in the accretion rate.
They note: “While T CrB clearly appears to be in the final stages before its next nova eruption, our analysis of its historical recurrence pattern suggests a significant scatter of at least 10 years around the mean ∼80-year period. Therefore, while an eruption is anticipated, the existing data do not allow for a precise prediction of its timing”.
The 80th anniversary of the detection of the last eruption falls in just over a fortnight.
PS: for those following the literature on this RN, another A&A submission today is on “Hydrodynamic simulations of the recurrent nova T Coronae Borealis: Nucleosynthesis predictions“.
