Effects of Heavy Elements and Excited States in the Equation of State of the Solar Interior
Zhigang Gong, Werner Dappen, Alan Nayfonov
Although 98% of the solar material consists of hydrogen and helium, the remaining chemical elements contribute in a discernible way to the thermodynamic quantities. The contributio…
On density and temperature-dependent ground-state and continuum effects in the equation of state for stellar interiors -- A Comment on the paper by S. Arndt, W. Dappen and A. Nayfonov 1998, ApJ 498, 349
Wolf-Dietrich Kraeft, Stefan Arndt, Werner Dappen +1
Misunderstandings have occurred regarding the conclusions of the paper by S. Arndt, W. Dappen and A. Nayfonov 1998, ApJ 498, 349. At occasions, its results were interpreted as if i…
The MHD equation of state with post-Holtsmark microfield distributions
Alan Nayfonov, Werner Dappen, David G. Hummer +1
The Mihalas-Hummer-Dappen (MHD) equation of state is a part of the Opacity Project (OP), where it mainly provides ionization equilibria and level populations of a large number of a…
Helioseismic analysis of the hydrogen partition function in the solar interior
S. Basu, W. Dappen, A. Nayfonov
The difference in the adiabatic gradient gamma_1 between inverted solar data and solar models is analyzed. To obtain deeper insight into the issues of plasma physics, the so-called…
