Dynamical mass of a solar-like oscillator at the main-sequence turnoff from Gaia astrometry & ground-based spectroscopy
P. G. Beck, T. Masseron, K. Pavlovski +11
Asteroseismology is widely used for precise determining of masses of solar-like oscillating stars by performing individual-frequency modeling or applying homological scaling relati…
Spectroscopic Alerts for the Time-Domain Era
Alejandra Melo, Paula Sanchez-Saez, Valentin D. Ivanov +13
Time-domain astronomy is entering an era of unprecedented discovery driven by wide-field, high-cadence surveys such as LSST, Roman, Euclid, SKA, and PLATO. While some of these faci…
White Dwarf Binaries: Probes of Future Astrophysics
Anna F. Pala, Roberto Raddi, Alberto Rebassa-Mansergas +25
White dwarf binaries are fundamental astrophysical probes. They represent ideal laboratories to test the models of binary evolution, which also apply to the sources of gravitationa…
Identification of new Galactic symbiotic stars with SALT -- II. New discoveries and characterization of the sample
J. Merc, J. Mikołajewska, K. Iłkiewicz +2
We present the continuation of a systematic search for new southern Galactic symbiotic stars, selecting candidates from the SuperCOSMOS H Survey and 2MASS. Follow-up spectroscop…
Revisiting symbiotic binaries with interferometry: II. New PIONIER data
Henri M. J. Boffin, Jaroslav Merc
Symbiotic stars, which generally comprise a red giant and an accreting white dwarf, are excellent laboratories to understand mass transfer in wide binaries, with application to a w…
ASASSN-24fw: Candidate circumplanetary disk occultation of a main-sequence star
Nadia L. Zakamska, Gautham Adamane Pallathadka, Dmitry Bizyaev +24
Dusty disks around planetary and substellar companions in outer reaches of exo-planetary systems can be detected as long-lasting occultations, provided the observer is close to the…
Is the Symbiotic Recurrent Nova T CrB Late? Recent Photometric Evolution and Comparison with Past Pre-Outburst Behaviour
Jaroslav Merc, Łukasz Wyrzykowski, Paul G. Beck +46
T CrB is a symbiotic recurrent nova that last erupted in 1946. Given its recurrence timescale of approximately 80 years, the next outburst is eagerly anticipated by the astronomica…
Symbiotic stars in the era of modern ground- and space-based surveys
Jaroslav Merc
Symbiotic stars, interacting binaries composed of a cool giant and a hot compact companion, exhibit complex variability across the electromagnetic spectrum. Over the past decades,…
The Local Group Symbiotic Star Population and its Tenuous Link with Type Ia Supernovae
Marco Laversveiler, Denise R. Gonçalves, Helio J. Rocha-Pinto +1
Binary stars are gravitationally bound stellar systems where the evolution of each component can significantly influence the evolution of its companion and the system as a whole. I…
Revisiting symbiotic binaries with interferometry. I. The PIONIER archival collection
Jaroslav Merc, Henri M. J. Boffin
Symbiotic stars serve as exceptional laboratories for investigating mass transfer processes in binary systems. However, the dominant mechanism of mass transfer from the red giant d…
Kepler meets Gaia DR3: homogeneous extinction-corrected color-magnitude diagram and binary classification
D. Godoy-Rivera, S. Mathur, R. A. García +8
The original Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields (e.g., asteroseismology and exoplanets), and cont…
Unequivocal detection of the tidal deformation of a red giant in a binary system via interferometry
Jaroslav Merc, Henri M. J. Boffin
While mass transfer in binary systems is a crucial aspect of binary evolution models, it remains far from understood. HD 352 is a spectroscopic binary exhibiting ellipsoidal variab…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
