Investigation of the recombination of the retarded shell of "born-again" CSPNe by time-dependent radiative transfer models
Antti Koskela, Silvia Dalnodar, Ralf Kissmann +3
A standard planetary nebula stays more than 10 000 years in the state of a photoionized nebula. As long as the timescales of the most important ionizing processes are much smaller,…
