Analytical Solutions for the Dynamics of Planetary Nebulae with and without Common Envelope Evolution
G. Garcia-Segura
We present new analytical solutions for the dynamics of planetary nebulae. These equations consider the temporal variation of the mechanical luminosity as well as the common envelo…
Planetary Nebula Evolution for Single Stellar Models. The Formation of Neutral Spikes
Guillermo Garcia-Segura, Arturo Manchado, Jesus A. Toala +2
Two-dimensional hydrodynamical simulations are presented from the formation up to the late evolution of planetary nebula, for 6 different stellar models from 1 to 5 Mo. The hydrody…
A comprehensive hydrodynamical study of SB DEM L50: understanding off-centre SNe and soft X-ray luminosity
Rogelio Orozco-Duarte, Guillermo García-Segura, Aida Wofford +1
The superbubbles (SBs) carved in the interstellar medium by stellar winds and supernovae (SNe) are filled with hot (10~K) gas that produces soft X-ray emission (0.3-2.0\,…
FastChem: A computer program for efficient complex chemical equilibrium calculations in the neutral/ionized gas phase with applications to stellar and planetary atmospheres
J. W. Stock, D. Kitzmann, A. B. C. Patzer +1
For the calculation of complex neutral/ionized gas phase chemical equilibria, we present a semi-analytical versatile and efficient computer program, called FastChem. The applied me…
