Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, About 400 hours of the Herschel Space Observatory’s time has been used by the Open Time Key Programme “TNOs are Cool: A survey of the trans-Neptunian region” to obtain PACS (70, 100 and 160 μm) and SPIRE (250, 350 and 500 μm) photometry of 132 objects representing different dynamical classes (resonant, classical, scattered disk and detached TNOs as well as Centaurs), including 25 binary systems. As leftovers of the formation of the Solar System TNOs and their physical properties provide constraints to the models of formation and evolution of the various dynamical classes. SPICA is going to be a main leap forward on the way that Herschel started in the characterization of TNOs by determining size, albedo and other surface properties. SPICA is going to cover the mid- to far-IR wavelengths where TNO SEDs peaks (currently covered with Herschel/PACS and Spitzer/MIPS together). While Herschel could observe about 10% of the known TNOs, with its increased sensitivity SPICA would be able to detect most (probably all) currently known TNOs. The observing strategy we used in our key program will also be relevant for SPICA observations to beat the confusion noise., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027086, レポート番号: JAXA-SP-17-010E}, pages = {389--391}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {The trans-Neptunian Objects after Herschel: What Could SPICA Add to the Understanding of the Kuiper Belt?}, volume = {JAXA-SP-17-010E}, year = {2018} }
