Formation and Evolution of [Wolf-Rayet] Planetary Nebulae through a Late Thermal Pulse
J. B. Rodríguez-González, R. Orozco-Duarte, J. A. Toalá +5
We present the first radiation-hydrodynamical simulations of the formation of a born-again planetary nebula (PN) triggered by a late thermal pulse (LTP). The 2D radiation-hydrodyna…

Analytical modeling of helium absorption signals of isothermal atmospheric escape
Hiroto Mitani, Rolf Kuiper
Atmospheric escape driven by extreme ultraviolet (EUV) radiation is a critical process shaping the evolution of close-in exoplanets. Recent observations have detected helium triple…

Physically motivated analytic model of energy efficiency for EUV-driven atmospheric escape of close-in exoplanets
Hiroto Mitani, Riouhei Nakatani, Rolf Kuiper
Extreme Ultraviolet (EUV) driven atmospheric escape is a key process in the atmospheric evolution of close-in exoplanets. In many evolutionary models, the energy-limited mass-loss…
