Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We present the result of Suzaku observations of two gamma Cas analogues. gamma Cas analogues are small group of early B-type stars with exceptionally hard thermal X-ray emission up to 30 keV. This is harder than any X-ray emitters of stellar origins. Despite the accumulating observational facts, the X-ray production mechanism of gamma Cas analogues is uncertain. We conducted Suzaku observations of two of the sources, HD110432 and HD161103, respectively in September 2008 for 25 ks and February 2009 for 72 ks. In this contribution, we summarize the result of our spectral and temporal analysis using the XIS and PIN data., 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: AA0064574074, レポート番号: JAXA-SP-09-008E}, pages = {204--205}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Suzaku X-ray Study of Two gamma Cas Analogues: HD110432 and HD161103}, volume = {JAXA-SP-09-008E}, year = {2010} }
