Partially Ionized Layers of Accreted Envelopes of Weakly and Strongly Magnetized Neutron Stars (2007)

M. Kramer, N. Wex, R. Wielebinski, Alexander Potekhin, Gilles Chabrier, Yuri Shibanov

. We study equilibrium properties of partially ionized hydrogen atmospheres and subphotospheric layers of weakly (with magnetic eld B 10 9 G) and strongly (B 10 10 G) magnetized neutron stars. In...

Testing Cosmological Variability Of The Proton-To-Electron Mass Ratio Using The Spectrum Of Pks 0528--250 (2007)

Alexander Potekhin, Er V. Ivanchik, Dmitry A. Varshalovich, Kenneth M. Lanzetta, Jack A. Baldwin, Gerard M. Williger, ...

Multidimensional cosmologies allow for variations of fundamental physical constants over the course of cosmological evolution, and different versions of the theories predict different time...

Heat and Charge Transport in Envelopes of Weakly and Strongly Magnetized Neutron Stars (2000)

M. Kramer, N. Wex, R. Wielebinski, Alexander Potekhin

. Thermal and electrical electron conductivities are calculated for a broad range of physical parameters typical for envelopes of neutron stars. An appropriate eective electron-ion scattering...

Photoionization Of Hydrogen In Atmospheres Of Magnetic Neutron Stars (1997)

Alexander Potekhin, George G. Pavlov

The strong magnetic fields (B ¸ 10 12 \Gamma 10 13 G) characteristic of neutron stars make all the properties of an atom strongly dependent on the transverse component K? of its generalized...
