- REDIRECT Template:Infobox astronomical event
SN 2005cs was a supernova in the spiral galaxy M51,[1] 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.[2] The event was positioned at an offset of Script error: No such module "val". west and Script error: No such module "val". south of the galactic nucleus of M51.[3] Based on the data, the explosion was inferred to occur 2.8 days before discovery.[4] It was considered under-luminous for a supernova of its type, releasing an estimated Script error: No such module "val". in energy.[5]
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 Script error: No such module "val".. A higher mass star enshrouded in a cocoon of dust has been ruled out.[6]
