The University of Tokyo), Bunkyo-ku, Tokyo, Japan, We perform a systematic study of the interstellar medium (ISM) and star formation for a large sample of local early-type galaxies (ETGs) based on the AKARI all-sky maps. Our sample galaxies are the 260 ETGs from the ATLAS(sup 3D) survey, for which cold gas measurements (CO and HI) are available. Combining the AKARI measurements with the 2MASS and WISE archival data, we modeled spectral energy distributions of the ETGs to derive the total dust and polycyclic aromatic hydrocarbon luminosities, and thus total dust masses and star formation rates (SFRs). We find that the dust-to-stellar mass ratios and the current SFRs of the ETGs are smaller than those of late-type galaxies (LTGs), showing that local ETGs are quiescent galaxies. We also find that the current star formation efficiencies of the ETGs are similar to those of LTGs. Our result suggests that low SFRs of local ETGs are likely caused by their smaller amounts of the cold ISM rather than a suppression of star formation., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730026019, レポート番号: JAXA-SP-17-009E},
