Gaia Data Release 3: Stellar multiplicity, a teaser for the hidden treasure

Gaia Collaboration, F. Arenou, C. Babusiaux +447

The Gaia DR3 Catalogue contains for the first time about eight hundred thousand solutions with either orbital elements or trend parameters for astrometric, spectroscopic and eclips…

Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry

Gaia Collaboration, P. Panuzzo, T. Mazeh +412

Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…

An impressionist view of V Hydrae. When MATISSE paints Asymmetric Giant Blobs

L. Planquart, C. Paladini, A. Jorissen +29

Our purpose is to study the effect of binary companions located within the first 10 stellar radii from the primary AGB star. In this work, we target the mass-losing carbon star V H…

X TrA through the eyes of MATISSE: More evidence of clumpy molecular layers around C-type asymptotic giant branch stars

V. Răstău, C. Paladini, J. Drevon +22

Aims. The goal of this study is to further the understanding of the wind formation mechanism in asymptotic giant branch (AGB) stars through the analysis of the close environment (w…

A dynamic view of V Hydrae. Monitoring of a spectroscopic-binary AGB star with an alkaline jet

L. Planquart, A. Jorissen, A. Escorza +2

The well studied carbon star V Hydrae is known to exhibit a complex asymmetric environment made of a dense equatorial wind and high-velocity outflows, hinting at its transition fro…

Resolving the mass transfer in the symbiotic recurrent nova T Coronae Borealis

L. Planquart, A. Jorissen, H. Van Winckel

T Coronae Borealis (T CrB) is a symbiotic recurrent nova with an 80-year recurrence interval whose next eruption is imminent. We aim to resolve the accretion mechanism of the binar…
