Common Envelope Evolution of Massive Stars
Paul M. Ricker, Frank X. Timmes, Ronald E. Taam +1
The discovery via gravitational waves of binary black hole systems with total masses greater than has raised interesting questions for stellar evolution theory. Among t…
Pulsar Timing Constraints on the Fermi Massive Black-Hole Binary Blazar Population
A. Miguel Holgado, Alberto Sesana, Angela Sandrinelli +4
Blazars are a sub-population of quasars whose jets are nearly aligned with the line-of-sight, which tend to exhibit multi-wavelength variability on a variety of timescales. Quasi-p…
Common Envelope Shaping of Planetary Nebulae
Guillermo Garcia-Segura, Paul M. Ricker, Ronald E. Taam
The morphology of planetary nebulae emerging from the common envelope phase of binary star evolution is investigated. Using initial conditions based on the numerical results of hyd…
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…
