Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We here present the results of the X-ray observations of two X-ray binaries, an eclipsing X-ray burster AX J1754.6-2901 and a recurrent X-ray burster GRS 1741.9-2853, in the Galactic Centre Region, conducted with XMM-Newton, Swift and INTEGRAL. We have detected AX J1745.6-2901 with XMM-Newton in its outburst in 2007, identifying seven eclipses with the period of 8.4 hours, as well as one-type-I X-ray burst. We have also found pseudo-periodical dipping natures in the light curve roughly 4000 seconds prior to each eclipse, though seen only in 5 cases out of 7 eclipses. Based on the spectral and timing natures, we conclude that those dips are likely to be caused with lumps of materials with each seize of < 10(exp 8) metres at the inner edge of the accretion disk. From GRS 1741.9-2853 we have detected 15 type-I bursts in total, during its outburst with the luminosity of 10(exp 36) to 10(exp 37) erg s(sup -1) , while we detected no burst during its quiescent state for 2.8 Ms exposure with INTEGRAL. The characteristics of the observed bursts suggest pure helium explosion, Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574099, レポート番号: JAXA-SP-09-008E}, pages = {272--273}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {21st century observation of AX J1745.6-2901 and GRS 1741.9-2853 in the Galactic Center}, volume = {JAXA-SP-09-008E}, year = {2010} }
