Detailed study of HD 219134: a benchmark K-dwarf with a compact planetary system

Jérôme Bétrisey, Camilla Pezzotti, Gaël Buldgen +4

Space missions such as CoRoT, Kepler, and TESS have transformed asteroseismology and its synergies with exoplanet science. We revisit the nearby K-dwarf HD 219134 to investigate th…

Multiplicity of northern bright O-type stars with optical long baseline interferometry

Cyprien Lanthermann, Jean-Baptiste Le Bouquin, Hugues Sana +16

The study of the multiplicity of massive stars gives hints on their formation processes and their evolutionary paths, which are still not fully understood. Large separation binarie…

Megahertz emission of massive early-type stars in the Cygnus region

Paula Benaglia, Michäel De Becker, C. H. Ishwara-Chandra +2

Massive, early type stars have been detected as radio sources for many decades. Their thermal winds radiate free-free continuum and in binary systems hosting a colliding-wind regio…

The high-energy emission from HD~93129A near periastron

S. del Palacio, F. García, D. Altamirano +12

We conducted an observational campaign towards one of the most massive and luminous colliding wind binaries in the Galaxy, HD~93129A, close to its periastron passage in 2018. Durin…

Long-term soft and hard X-ray investigation of the colliding wind WN+O binary WR 25

Bharti Arora, J. C. Pandey, M. De Becker

We investigated the long-term behaviour in X-rays of the colliding wind binary WR 25, using archival data obtained with Suzaku, Swift, XMM-Newton, and NuSTAR spanning over ~16 year…

Positron Annihilation in the Galaxy

Carolyn A. Kierans, John F. Beacom, Steve Boggs +27

The 511 keV line from positron annihilation in the Galaxy was the first -ray line detected to originate from outside our solar system. Going into the fifth decade since the disc…
