SN 2007uy
Template:Infobox astronomical event SN 2007uy was a supernova that occurred in the spiral galaxy NGC 2770. It was discovered by Yoji Hirose on December 31, 2007 from Chigasaki city in Japan,[1] approximately four days after the explosion.[2] The position of the supernova was offset Script error: No such module "val". east and Script error: No such module "val". south of the galaxy's nucleus,[3] near a star-forming region.[4] It was identified as a Type Ib supernova from its spectrum a week before reaching maximum, and appeared the most similar to SN 2004gq.[5]
Emissions from SN 2007uy were detected from the X-ray to the radio band.[6] The light from this event was heavily reddened due to intervening dust in the host galaxy. This energetic explosion released Script error: No such module "val". in energy and ejected a mass of Script error: No such module "val"..[2] The progenitor was likely a massive star that had been stripped of its hydrogen envelope by a binary companion.[4] There is no radio evidence of a relativistic jet of the type that would be associated with a gamma-ray burst.[6]
While interesting in its own right, SN 2007uy was overshadowed by SN 2008D, a supernova whose burst was observed serendipitously while SN 2007uy was being studied by Swift, something unprecedented in astronomy.[7] This second supernova occurred within ten days of the first.[6]
