astro.wikisort.org - StarSN 2005cs was a supernova in the spiral galaxy M51,[3] known as the Whirlpool Galaxy. It was a type II-P core-collapse supernova, discovered June 28, 2005 by Wolfgang Kloehr, a German amateur astronomer.[5] The event was positioned at an offset of 15″ west and 78″ south of the galactic nucleus of M51.[2] Based on the data, the explosion was inferred to occur 2.8 days before discovery.[6] It was considered under-luminous for a supernova of its type, releasing an estimated 3×1050 erg in energy.[4]

The progenitor star was identified from a Hubble Space Telescope image taken January 20–21, 2005. It was a red supergiant with a spectral type in the mid-K to late-M type range and an estimated initial (ZAMS) mass of 9+3
−2 M☉. A higher mass star enshrouded in a cocoon of dust has been ruled out.[7]

Die Supernova SN 2005cs war eine Supernova vom Typ II, die am 28. Juni 2005 in der Whirlpoolgalaxie (M51) aufflammte. SN 2005cs wurde von Wolfgang Kloehr mit Amateurmitteln zufällig entdeckt. Da es sich bei M51 um eine recht prominente Galaxie handelt, existierten auch vor der Supernova bereits hochaufgelöste Fotografien von Teleskopen wie dem Hubble-Weltraumteleskop. Daher konnten Wissenschaftler im Nachhinein den explodierten Stern auf einer früheren Aufnahme identifizieren.[1]
