概要
- 論文の詳細を見る
The X-ray time variation of GRS 1915+105 is analyzed, focusing on the phase lag properties in the class 9. An energy dependent soft lag is derived. This energy dependence can be interpreted in terms of the Comptonization of high energy photons by relatively soft electrons. A Monte Carlo simulation of the Comptonization is calculated. In this computation, photons with a power-law spectrum are scattered by soft electrons. This model can account for both the spectral properties and the time variation. With this model, the size of the electron cloud which is responsible for the Comptonization is derived to be 〜3.2×10^<7-8>cm.
