Model X-ray Spectra of Magnetic Neutron Stars with Hydrogen Atmospheres
Wynn C. G. Ho, Alexander Y. Potekhin, Gilles Chabrier
We construct partially ionized hydrogen atmosphere models for magnetized neutron stars in radiative equilibrium with fixed surface fields between B=10^12 and 2x10^13 G and effectiv…
Detailed Analysis of Balmer Lines in a Sloan Digital Sky Survey Sample of 90 Broad Line Active Galactic Nuclei
G. La Mura, L. Č. Popović, S. Ciroi +2
In order to contribute to the general effort aiming at the improvement of our knowledge about the physical conditions within the Broad Line Region (BLR) of Active Galactic Nuclei (…
Updated Electron-Conduction Opacities: The Impact on Low-Mass Stellar Models
S. Cassisi, A. Y. Potekhin, A. Pietrinferni +2
We review the theory of electron-conduction opacity, a fundamental ingredient in the computation of low-mass stellar models; shortcomings and limitations of the existing calculatio…
The Mass of the Black Hole in the Seyfert 1 Galaxy NGC 4593 from Reverberation Mapping
Kelly D. Denney, Misty C. Bentz, Bradley M. Peterson +15
We present new observations leading to an improved black hole mass estimate for the Seyfert 1 galaxy NGC 4593 as part of a reverberation-mapping campaign conducted at the MDM Obser…
Detection of Giant Pulses in pulsar PSR J1752+2359
A. A. Ershov, A. D. Kuzmin
We report the detection of Giant Pulses (GPs) in the pulsar PSR J1752+2359. About one pulse in 270 has a peak flux density more than 40 times the peak flux density of an average pu…
The magnetic structure of neutron stars and their surface-to-core temperature relation
A. Y. Potekhin, V. Urpin, G. Chabrier
We study the relation between the mean effective surface temperature T_s and the internal temperature T_b for magnetic neutron stars, assuming that the magnetic field near the surf…
