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…

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…
