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…
Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
V4141 Sgr: Outflows and repeated outbursts
Jaroslav Merc, Joanna Mikołajewska, Thomas Petit +6
In this work, we analyze the ongoing brightening of the poorly studied symbiotic star V4141 Sgr and examine its long-term variability. We present new low-resolution spectroscopic o…
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…
Gaia18aen: First symbiotic star discovered by Gaia
J. Merc, J. Mikołajewska, M. Gromadzki +20
Besides the astrometric mission of the Gaia satellite, its repeated and high-precision measurements serve also as an all-sky photometric transient survey. The sudden brightenings o…
Spectroscopic orbits of three dwarf barium stars
P. L. North, A. Jorissen, A. Escorza +2
Barium stars are thought to result from binary evolution in systems wide enough to allow the more massive component to reach the asymptotic giant branch and eventually become a CO…
