Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3

Jaroslav Merc, Lionel Mulato, Joanna Mikołajewska +7

We investigate the reliability of the symbiotic star class in the general variability classification of Gaia DR3 and search for new genuine symbiotic systems among the objects assi…

Revisiting atmospheric Roche lobe overflow in symbiotic binaries

Tan Liu, Natalia Ivanova, Philipp Podsiadlowski +5

Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios, leading to a common envelope. However, many observed S-type s…

Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi

Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14

EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…
