Grand Park Otaru Hotel), Otaru, Hokkaido Japan, In order to search for possible non-thermal emission like AE Aquarii (Terada et al. 2008), we picked up magnetized isolated white dwarfs (WDs) in addition to binaries including magnetized cataclysmic variables. Recently, many magnetized WDs are found by Sloan Digital Sky Survey project reaching 9300 objects (Kauwa et al.2006), including WDs showing a magnetic field strength of B approximately 10(exp 9) G. 21 objects were selected with known magnetic field strength and spin periods in terms of magnetic dipole momentum. The most promising object was EUVE J0317-855, which has B approximately 4.5 x 10(exp 9) G and spin period of 725 sec. Among them, non thermal emission from best ten objects were searched from the archive data-sets with INTEGRAL IBIS/ISGRI in 20 - 40 keV band. As a result, no significant emissions were detected from these WDs with INTEGRAL sensitivities, and estimated upper limit of their flux as from 2.8 x 10(exp -12) to 3.0 x 10(exp -11) erg s(exp -1)cm(exp -2)., 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: AA0064574075, レポート番号: JAXA-SP-09-008E}, pages = {206--207}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Search for non-thermal emission from isolated magnetized white dwarfs with INTEGRAL}, volume = {JAXA-SP-09-008E}, year = {2010} }
