摘要: We perform the analysis of iron K_alpha lines detected in three sources representing types accreting compact sources: cataclysmic variable (CV) GK Per, neutron star (NS) Serpens X-1 and black hole (BH) GX 339-4. find, using data from Epic-PN Camera on-board XMM-Newton observatory,that emission line Per has a noticeable red-skewed profile. compare asymmetric with observed by The observation features CV cannot be related to redshift effects General Relativity (GR). Therefore, if mechanism K_alpha-line formation is same CVs, NSs BHs then it evident that GR would ruled out as cause red skewness line. reprocessing an outflowing wind been recently suggested alternative model for broad red-shifted formation. In framework outflow scenario formed strong extended due its illumination radiation emanating innermost part material. this Paper we demonstrate shapes these CV, NS BH are well described (outflow) model. While fact hard reconcile relativistic models, consistent gas washing high frequency modulations presumably originated source.
