WD Periastron Passage in the R Aqr System: Zooming on the New Ejecta and Jet
Abstract
We propose HST observations of the R Aqr symbiotic binary system, jointly with Chandra and VLA, as a follow up on the 2020 and 2021 archival observations which show dramatic changes within 1 from the central binary resulting from the enhanced accretion during the recent periastron passage of the white dwarf (WD) accretor. These phenomena are observable in R Aqr only about twice a century, with the next periastron expected in about 40 years. Our goal is to carry out a timely high-angular resolution multi-wavelength study of this event by zooming in on the central 3 radius circumbinary region. This will allow us to determine the spatial/spectral evolution of the distribution and the characteristics of the new ejecta and jet, and to gain a unique insight into jet formation and early pr
