VERIFICATION OF THE BEAMING EFFECT OF FE LINE BY RESONANCE SCATTERING WITH MCVS


ABSTRACT

AX J1842.8-0423 and RXJ1802.1+1804, observed with ASCA in 1996, exhibit a strong Fe-K line with an extremely large equivalent width 4000 eV .These objects are thought to be magnetic white dwarf binary, so called Polar(or AM Herculis object). The accretion column of a magnetized white dwarf is usually quite opaque to resonance scattering for Fe-K line.So, we consider, in some extraordinary condition, Fe-K line photon will be collimated strongly by resonance scattering.Our proposal is to observe Polars with pole-on inclination angle, and to test this beaming effect of Fe line.
