Towards Non-spherical Radio Models

TL;DR

This paper develops techniques to model non-spherical radio emissions from novae, revealing that previous spherical assumptions may have led to overestimations of ejected masses, thus improving physical parameter retrieval.

Contribution

It introduces morpho-kinematical methods for non-spherical radio light curve modeling, addressing a gap in nova outburst analysis.

Findings

Non-spherical models affect ejected mass estimates.

Morpho-kinematical techniques enable more accurate light curve fitting.

Previous spherical assumptions may overestimate nova ejected masses.

Abstract

Radio observations of novae in outburst are of particular interest due to the physical parameters that may be retrieved from fitting the radio light curves. Most models that have fitted previous data assumed spherical symmetry however, it is becoming more and more clear that this is not the case. We explore morpho-kinematical techniques to retrieve the free-free radio light curves of non-spherical models and explore the effects of a non-spherical outburst on the physical parameters. In particular, we find that we may have been over estimating the ejected masses in the outburst of non-spherical novae.
