DESCRIPTION:EVN Seminar: Rocco Lico on Capturing the Real-Time Expansion a
 nd Evolution of Symbiotic Novae\n\n\nJoin via Zoom (Meeting ID: 876 4980 9
 023\; https://astron.zoom.us/j/87649809023) or via the YouTube streaming i
 n the JIVE and EVN channel (https://youtube.com/live/bK1qFsFdyTE). More in
 formation at https://evlbi.org/evn-seminars. Abstract: Nova outbursts are 
 among the most energetic phenomena in binary star systems\, driven by ther
 monuclear runaway on the surface of a white dwarf. In symbiotic systems\, 
 where the companion is a red giant\, the explosion propagates through a de
 nse circumbinary environment\, offering a unique laboratory for high-energ
 y astrophysics. In this talk\, I will explore the structural and physical 
 evolution of symbiotic novae\, using the 2021 outburst of RS Ophiuchi (RS 
 Oph) as a primary case study. As the first nova ever detected at very-high
  energies (E>100 GeV)\, RS Oph provides a unique window into particle acce
 leration and shock dynamics. I will present high-resolution monitoring fro
 m the European VLBI Network (EVN) at 1.65 and 5 GHz\, spanning 14 to 65 da
 ys post-explosion. These observations allow us to characterize the expandi
 ng bipolar ejecta and the surrounding medium in unprecedented detail\, ena
 bling us to constrain critical system parameters for symbiotic stars\, inc
 luding outflow velocities\, the white dwarf accretion rate\, the red giant
  mass-loss rate\, the circumbinary density profile\, and the properties of
  the orbital-plane density enhancement.
