Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We report the discovery of a approximately0.8 keV emission component from the Galactic disk with Suzaku. Using two Suzaku observations and re-analysis of ROSAT All Sky map, we conclude that the emission component exists over the entire galactic plane. This is likely an answer to the long standing mystery of the "M-band problem" identified in the early 1980's. Since high pressure is required to explain the 0.8 keV emission, diffuse gas is unlikely an explanation of the emission. Instead, we constructed a model which assumes that the emission originates from unresolved faint M dwarf (dM) stars in the Suzaku field of view. This model successfully represents the energy spectrum, the absolute intensity, and the latitude dependence of the emission., 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: AA0064574040, レポート番号: JAXA-SP-09-008E}, pages = {108--109}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Discovery of the approximately0.8 keV emission component from the Galactic disk with Suzaku}, volume = {JAXA-SP-09-008E}, year = {2010} }
