STELLAR CHEMISTRY
A massive stellar burst, before the supernova
Berkeley CA (SPX) Feb 11, 2013
An automated supernova hunt is shedding new light on the death sequence of massive stars-specifically, the kind that self-destruct in Type IIn supernova explosions. Digging through the Palomar Transient Factory (PTF) data archive housed at the Department of Energy's National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (Berkeley Lab), astronomers have found the first causal evidence that these massive stars shed huge amounts of material in a "penulti ... read more
