Models of the iron K_alpha fluorescence line and the Compton shoulder in irradiated accretion disk spectra
Agata Różańska, Jerzy Madej
We present a full set of model atmosphere equations for the accretion disk around a supermassive black hole irradiated by hard X-ray lamp of power-law spectral distribution. Model…
On the Relevance of Compton Scattering for the Soft X-ray Spectra of Hot DA White Dwarfs
V. Suleimanov, J. Madej, J. J. Drake +2
We re-examine the effects of Compton scattering on the emergent spectra of hot DA white dwarfs in the soft X-ray range. Earlier studies have implied that sensitive X-ray observatio…
Mass and radius determination for the neutron star in X-ray burst source 4U/MXB 1728-34
A. Majczyna, J. Madej
We analyzed archival X-ray spectra of MXB 1728-34 obtained in 1996-99 by the Proportional Counter Array on board of the RXTE satellite. X-ray spectra were fitted to our extensive g…
Secular variability of the longitudinal magnetic field of the Ap star gamma Equ
V. D. Bychkov, L. V. Bychkova, J. Madej
We present an analysis of the secular variability of the longitudinal magnetic field B_e in the roAp star gamma Equ (HD 201601). Measurements of the stellar magnetic field B_e were…
Model atmospheres and X-ray spectra of iron-rich bursting neutron stars. II. Iron rich Comptonized Spectra
A. Majczyna, J. Madej, P. C. Joss +1
This paper presents the set of plane-parallel model atmosphere equations for a very hot neutron star (X-ray burst source). The model equations assume both hydrostatic and radiative…
Theoretical UBVRI colors of iron core white dwarfs
J. Madej, M. Pietrachowicz, P. C. Joss +3
We explore photometric properties of hypothetical iron core white dwarfs and compute their expected colors in UBVRI Johnson broadband system. Atmospheres of iron core WDs in this p…
