Formation and Evolution of [Wolf-Rayet] Planetary Nebulae through a Late Thermal Pulse
J. B. RodrÃguez-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…

Formation and X-ray emission from hot bubbles in planetary nebulae - III. The impact of [Wolf-Rayet]-type winds
Rogelio Orozco-Duarte, Jesús A. Toalá, S. Jane Arthur +3
We use radiation-hydrodynamical simulations to investigate the formation and synthetic X-ray emission of hot bubbles within planetary nebulae (PNe) driven by the powerful winds of…

Y Gem, a symbiotic star outshone by its asymptotic giant branch primary component
M. A. Guerrero, D. A. Vasquez-Torres, J. B. RodrÃguez-González +2
A considerable number of asymptotic giant branch (AGB) stars exhibit UV excess and/or X-ray emission that indicates a binary companion. AGB stars are so bright that they easily out…
