Nova Centauri 2013 | John Seach


Nova Centauri 2013 (V1369 Cen, Nova Cen 2013) was discovered by John Seach on 2013 December 02.692 UT in the constellation Centaurus. This was John's 9th Nova discovery.

Nova Centauri 2013 is the 16th brightest nova observed, and at its brightest was the 227th brightest star in the sky.

Nova Centauri 2013 (V1369 Cen) was the first nova shown to create Lithium. This helped solve the Lithium problem in cosmology. Lithium was created between 10 seconds and 20 minutes after the big bang. Previously there was no explanation for the difference in Lithium in old versus young stars. The discovery in Lithium creation in Nova Cen 2013 solved this mystery.

According to the Hot Big Bang Theory, Lithium lithium-7 is produced either by tritium-α fusion, or through beryllium-7.
