HR 6819 is a binary system with no black hole -- revisiting the source with infrared interferometry and optical integral field spectroscopy

A. J. Frost, J. Bodensteiner, Th. Rivinius +16

Two scenarios have been proposed to match the existing observational constraints of the object HR 6819. The system could consist of a close inner B-type giant plus a black hole (BH…

The 13O-rich atmosphere of a young accreting super-Jupiter

Yapeng Zhang, Ignas Snellen, Alexander J. Bohn +8

Isotope abundance ratios play an important role in astronomy and planetary sciences, providing insights in the origin and evolution of the Solar System, interstellar chemistry, and…

Discovery of a directly imaged planet to the young solar analog YSES 2

Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +8

Abbreviated. By selecting stars with similar ages and masses, the Young Suns Exoplanet Survey (YSES) aims to detect and characterize planetary-mass companions to solar-type host st…

A dusty filament and turbulent CO spirals in HD135344B-SAO206462

Simon Casassus, Valentin Christiaens, Miguel Carcamo +16

Planet-disc interactions build up local pressure maxima that may halt the radial drift of protoplanetary dust, and pile it up in rings and crescents. ALMA observations of the HD135…

A faint companion around CrA-9: protoplanet or obscured binary?

V. Christiaens, M. -G. Ubeira-Gabellini, H. Cánovas +16

Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition disc…

VIBES: VIsual Binary Exoplanet survey with SPHERE Upper limits on wide S-planet and S-BD frequencies, triple system discovery, and astrometric confirmation of 20 stellar binaries and three triple systems

J. Hagelberg, N. Engler, C. Fontanive +7

Recent surveys indicate that planets in binary systems are more abundant than previously thought, which is in agreement with theoretical work on disc dynamics and planet formation…
