Nova Cen 2013 or V1369 Cen (PNV J13544700-5909080) was a bright nova in the constellation Centaurus. It was discovered on December 2, 2013 by amateur astronomer John Seach in Australia with a magnitude of 5.5.[3][4]
On December 14, 2013 it peaked at about magnitude 3.3, making it the brightest nova of this millennium.[5]
Nova Centauri 2013 was observed emitting gamma-rays between 7–10 December 2013 by the Fermi Gamma-ray Space Telescope.[6] The nova continued to brighten in gamma-rays and the peak coincided with the second optical maximum on 11 December 2013.[7]
The Swift Gamma-Ray Burst Mission detected X-ray emission from Nova Centauri 2013 on 18 and 25 February 2014 and 8 March 2014.[8]
In July 2015 it was announced that lithium has been detected in material ejected from Nova Centauri 2013. This is the first time lithium has been detected in a nova system.[9][dubious ] The amount detected was less than a billionth of the mass of the Sun.[9] This finding is significant because it supports a theory that the extra lithium found in Population I stars (compared to Population II stars) comes from novae.[9]
