AG Peg: a new paradigm?

Friends,

A new paper appeared today on arXiv on AG Peg's peculiar behavior, captured by the AAVSO light curve and Swift x-ray data. The main conclusion is that "AG Peg's transition from a slow symbiotic nova (which drove the 1850 outburst) to a classical symbiotic star suggests that shell burning in at least some symbiotic stars is residual burning from prior novae". This result connects nova explosions in symbiotic stars with nuclear burning on their white dwarf in their non-nova ("quiescence") state. The full paper can be found here:

Enjoy!

Best wishes - clear skies,

Stella.
