U Scorpii 2010 outburst: observational evidence of an underlying ONeMg white dwarf.

MASON E.

Abstract (from CDS):

This paper presents USco nebular spectra collected in the period March-May 2010 after the binary outburst on Jan. 28, 2010. The spectra display strong [Nev] and [Neiii] lines that can be used to compute the relative abundance of [Ne/O]. The value obtained ([Ne/O]=1.69) is higher than the typical [Ne/O] abundance found in classical novae from CO progenitors and suggests that USco has a ONeMg white-dwarf progenitor. It follows that USco will not explode as a SNIa but rather collapse to become a neutron star or a millisecond pulsar.
