SN 2005E (aka 2005-1032) is a supernova first observed in January 2005 that scientists conclude is a new type of cosmic explosion.〔Marlowe Hood: "(Blast from the past: a new type of exploding star )" in Yahoo! News, May 19, 2010, 5:04 PM ET.〕 The explosion originated in the galaxy NGC 1032, approximately 100 million light years away.〔"(SN 2005E )" in Astrosurf - ''Portail d'Astronomie des astronomes amateurs francophones'' (French)〕〔Stephen Battersby: "(Quirky supernova could be something new )", ''New Scientist'', 19 June 2009.〕 Location: RA 02° 39' 14.34" Dec+01hr 05' 55.0" (J2000 ) ==Research and Conclusions== On May 19, 2010, a team of astronomers released a report on the discoveries made in their research of SN 2005E. The articles were published in the British journal ''Nature''.〔"(A faint type of supernova from a white dwarf with a helium-rich companion )", ''Nature'', 465, 322–325 (20 May 2010), ; Received 17 May 2009; Accepted 23 March 2010.〕 The researchers have determined that the blast emitted a large amount of calcium and titanium, which is evidence of a nuclear reaction involving helium, instead of the carbon and oxygen that is characteristic of Type Ia supernovae. As these are recent developments, it is not known yet whether with the current research academia will classify SN 2005E as a new subclass of Type I supernovae (Type Id), or create a Type III category. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SN 2005E」の詳細全文を読む スポンサード リンク
