X-ray spectrum from the accretion columns of magnetic white dwarfs. (1990). Revista Mexicana De Astronomía Y Astrofísica, 21(1), 437. https://astronomia.unam.mx/journals/rmxaa/article/view/1990rmxaa..21..437f
Abstract
The authors study a general model of the accretion column of magnetic white dwarfs (e.g. as in AM Herculis binaries) consisting of five regions: (1) a shocked region; (2) a heated preshocked region above region (1); (3) a cool preshocked region above region (2); (4) a surrounding halo; and (5) the surface of the white dwarf. The authors find: (1) the width of the iron peak is ≡0.8 keV and relatively insensitive to the transverse Thomson optical depth; (2) if a halo exists it is very thin or has a very low density; and (3) the transverse Thomson optical depth ≡0.6.Similar Articles
