Abstract

High resolution radio images of γ-ray nova V959 Mon using e-MERLIN are presented here, at epochs in September 2012, November 2012, February 2013, October 2013 and February 2014. A light curve at C-Band frequency has been produced which is in good agreement with contemporaneous VLA observations. While early e-MERLIN observations of V959 Mon appear to show an east-west elongation in the ejecta morphology, subsequent observations show that the ejecta are now elongated in the north-south direction. Our high-resolution observations of the structure of V959 Mon can assist us in further understanding the mechanisms of mass ejection from novae.
