Grand Park Otaru Hotel), Otaru, Hokkaido Japan, A fair fraction of Galactic stellar-mass black holes are reported to be rapidly spinning, based on their broad Fe-K lines. However, such broad features couple strongly with the spectral continuum, and cause the modeling to degenerate. By carefully analyzing broad-band Suzaku data, and also employing the information on optically-thick disk emission, GX 339-4 is inferred to harbor a low-spin black hole. In addition, the Suzaku spectra of the Seyfert galaxy MCG-6-30-15 are interpreted in an alternative way, without invoking the rapid black-hole spin., 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: AA0064574093, レポート番号: JAXA-SP-09-008E}, pages = {252--255}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Continua and Iron-K Lines from Accreting Black Holes}, volume = {JAXA-SP-09-008E}, year = {2010} }
