The 2010 early outburst spectrum of the recurrent nova U Scorpii.

KAFKA S. and WILLIAMS R.

Abstract (from CDS):

We present optical spectra of the fast recurrent nova U Sco during its recent outburst, obtained within 24 h of maximum light. We use medium resolution (R∼4000) spectra taken with the with the MagE spectrograph on the Magellan (Clay) 6.5 m telescope of the Las Campanas Observatories. The spectrum is notable for its lack of a low ionization transient heavy element absorption system that is visible in the large majority of novae near maximum light. We suggest that this may be due to the dominance of inner Lagrangian L1 mass transfer and the absence of a circumbinary gas reservoir in this object.
