Entering the Wind Roche Lobe Overflow realm in Symbiotic Systems
R. F. Maldonado, J. A. Toalá, E. Tejeda +1
We present a suite of dynamical simulations designed to explore the orbital and accretion properties of compact (27 AU) symbiotic systems, focusing on wind accretion, drag force…

The impact of wind accretion in Evolving Symbiotic Systems
R. F. Maldonado, J. A. Toalá, J. B. RodrÃguez-González +1
We investigate the impact of geometric corrections to the Bondi-Hoyle-Lyttleton (BHL) accretion scheme applied to evolving symbiotic systems. We model systems where 0.7 and 1 M$_\o…

The impact of periastron passage on the X-ray and optical properties of the Symbiotic System R Aquarii
D. A. Vásquez-Torres, J. A. Toalá, A. Sacchi +4
Multi-epoch Chandra and XMM-Newton observations of the symbiotic system R Aquarii (R Aqr) spanning 22 yr are analysed by means of a reflection model produced by an accretion disc.…
