The carbon isotope ratio of β Pic b with high-resolution spectroscopy
D. González Picos, I. A. G. Snellen, R. Landman +6
Isotopic ratios trace the formation and evolution of planets and link their atmospheres to the chemistry of their natal protoplanetary discs. We measure $^{12}\mathrm{C}/^{13}\math…
Upper limits on exosatellites around Pictoris b
M. A. Kenworthy, R. Landman, A. Vanderburg +8
Pictoris b is one of the closest known directly-imaged gas giant exoplanets with an orbit that is almost edge-on to our line of sight, making it an ideal target for radial vel…
The spectral energy distribution of YSES 1 b and its circumplanetary disc
Michiel Darcis, Sebastiaan Y. Haffert, Tomas Stolker +18
Context. Direct imaging enables the characterisation of substellar companions on wide orbits. These objects provide a testbed for our formation theories; therefore, it is important…
Interior-Atmosphere Coupling on TRAPPIST-1 f, g, and h: Cryovolcanic Water Exospheres and Infrared Detectability
E. Kleisioti, D. Dirkx, A. V. Oza +4
We investigate the interior structures and cryovolcanic observability of the exoplanets TRAPPIST-1f, g, and h. Our aim is to determine which interior configurations can sustain sub…
Direct spectroscopic confirmation of the young embedded proto-planet WISPIT 2c
Chloe Lawlor, Richelle F. van Capelleveen, Guillaume Bourdarot +18
WISPIT 2 is a nearby young star with a multi-ringed disk which was recently confirmed to host a ~4.9 MJup gas giant planet embedded in a large (60 au) gap at a radial separation of…
The next frontier in exoplanet science: Imaging our neighbouring planetary systems
Ignas Snellen, Sebastiaan Haffert, Matthew Kenworthy +1
Transmission and eclipse spectroscopy have been invaluable tools for the characterisation of extrasolar planet atmospheres. While they will continue to provide many new insights an…
