Spectroscopic monitoring of long secondary period variables. The case of J-type carbon stars
L. Planquart, A. Jorissen, H. Van Winckel
Long-secondary-period (LSP) variables are a subclass of long-period variables whose origin is a matter of debate. J-type carbon stars are a subclass of carbon stars enriched in 13C…
The SB9 catalogue: status, comparison with non-single stars from Gaia DR3 and evolution to SBX
T. Merle, A. Jorissen, S. Alexandre +9
The Ninth Catalogue of Spectroscopic Binary Orbits (SB9) is a comprehensive compilation of spectroscopic binaries (SBs) with orbital parameters sourced from literature, comprising…
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…
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…
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…
The 33 M black hole Gaia BH3 is part of the disrupted ED-2 star cluster
E. Balbinot, E. Dodd, T. Matsuno +19
The Gaia Collaboration has recently reported the detection of a 33 M black hole in a wide binary system located in the Solar neighbourhood. Here we explore the relationship…
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…
The Gaia-ESO Survey: new spectroscopic binaries in the Milky Way
M. Van der Swaelmen, T. Merle, S. Van Eck +14
The Gaia-ESO Survey (GES) is a large public spectroscopic survey which acquired spectra for more than 100000 stars across all major components of the Milky Way. In addition to atmo…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
Reprocessing the Hipparcos data for evolved stars III Revised Hipparcos period-luminosity relationship for galactic long-period variable stars
G. R. Knapp, D. Pourbaix, I. Platais +1
We analyze the K band luminosities of a sample of galactic long-period variables using parallaxes measured by the Hipparcos mission. The parallaxes are in most cases re-computed fr…
Reprocessing the Hipparcos data for evolved giant stars II. Absolute magnitudes for the R-type carbon stars
G. R. Knapp, D. Pourbaix, A. Jorissen
The Hipparcos Intermediate Astrometric Data for carbon stars have been reprocessed using an algorithm which provides an objective criterion for rejecting anomalous data points and…
