Dynamic Evolution of the Powerful Jet Activity in the Symbiotic System R Aqr
Abstract
We propose to carry out JVLA A configuration observations of symbiotic system R Aqr, a very active interacting binary system with a powerful jet activity. Our goal is to study the physical characteristics and the dynamic evolution of the multi-scale radio components of the jet since the last VLA observations from 2005, including in the inner jet/counter jet region and the outer jet structures and jet-lobes. These high-angular resolution high-sensitivity observations at several frequencies when combined with the results from Chandra and HST observations (scheduled for late October 2017) will allow us to determine: (1) the spatial and spectral characteristics of the central region and the inner jet at scales comparable with the angular separation, (2) the jet dynamical evolution as it propagates and interacts with the surrounding close circumbinary environment, (3) if the inner jet is continuous with occasional ejections of parcel material, and (4) if the jet precesses.
