Symbiotic binaries in the Gaia data. II. Symbiotic candidates from general variability classification in DR3
Jaroslav Merc, Lionel Mulato, Joanna MikoÅajewska +7
The paper evaluates how well Gaia DR3’s general variability classification identifies symbiotic binaries, finds that many new candidates are actually pulsating red giants, and uses…
Analysis of the Gaia DR3 planetary nebula candidates and the possible symbiotic stars among them
Lionel Mulato, Jaroslav Merc, Stéphane Charbonnel +3
The Gaia DR3, released in June 2022, included low-resolution BP/RP (XP) spectra that have been exploited for the classification of various types of emission-line objects using mach…
V4141 Sgr: Outflows and repeated outbursts
Jaroslav Merc, Joanna MikoÅajewska, 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…
The birth of Be star disks I. From localized ejection to circularization
J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35
Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…
Search for new Galactic Wolf-Rayet stars using Gaia DR3. I. Candidate selection and the follow-up of the bright sample
Lionel Mulato, Jaroslav Merc, Stéphane Charbonnel +3
Gaia DR3, released in June 2022, included low-resolution XP spectra that have been used for the classification of various types of emission-line objects through machine-learning te…
