IPTF14hls
iPTF14hls is an unusual supernova star that erupted continuously for about 1,000 days beginning in September 2014 before becoming a Supernova remnant, remnant nebula. It had previously erupted in 1954. None of the theories nor proposed hypotheses fully explain all the aspects of the object. Observations The star iPTF14hls was discovered in September 2014 by the Intermediate Palomar Transient Factory, and it was first made public in November 2014 by the Catalina Real-time Transient Survey, CRTS survey as CSS141118:092034+504148. Based on that information it was confirmed as an exploding star in January 2015. It was thought then that it was a single supernova event (Type II supernova, Type II-P) that would dim in about 100 days, but instead, it continued its eruption for about 1,000 days while fluctuating in brightness at least five times. The brightness varied by as much as 50%, going through five peaks. Also, rather than cooling down with time as expected of a Type II super ...
