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…
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…
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,…
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…
Accretion-induced flickering variability among symbiotic stars from space photometry with NASA TESS
J. Merc, P. G. Beck, S. Mathur +1
Symbiotic binaries exhibit a wide range of photometric variability spanning different timescales attributed to orbital motion, intrinsic variability of individual components, or th…
Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems -- A census of oscillating red-giants and main-sequence stars in Gaia DR3 binaries
P. G. Beck, D. H. Grossmann, L. Steinwender +23
Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems containing a oscillating component are interesting…
Independent Study and Spectral Classification of a Sample of Poorly Studied High Proper Motion M-dwarf Candidate Stars
Cristina Cabello, Géza Csörnyei, Jaroslav Merc +2
We report an independent spectral classification of a sample of poorly studied M-dwarf candidate stars observed with the OSIRIS instrument at GTC. Our project was carried out as an…
