Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, The evolution of Polycyclic Aromatic Hydrocarbon (PAH) emission of carbon-rich Galactic planetary nebulae (PNe) is investigated based on AKARI/IRC and Spitzer/IRS observations. Systematic variations in band peak positions and relative intensities are discovered in terms of evolution of PNe. The results show that PAHs in evolved PNe tend to show similar features as interstellar PAHs. The SPICA/MRS will have the advantage to investigate the evolution of dust emission in the 15-40 μm region. We discuss potential observations with SPICA to develop our understanding of the evolution of dust emission., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027057, レポート番号: JAXA-SP-17-010E}, pages = {265--267}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Evolution of Dust Emission around PNe, from AKARI/Spitzer to SPICA}, volume = {JAXA-SP-17-010E}, year = {2018} }
