Direct Imaging Discovery of Giant Exoplanet Pictoris d: A Decade-Long Game of Hide-and-Seek
Ben J. Sutlieff, Markus J. Bonse, Valentin Christiaens +94
The paper reports the direct imaging discovery of a third giant exoplanet, β Pictoris d, using VLT/ERIS and archival JWST/NIRCam and VLT/SPHERE data, and characterizes its orbit, t…
The CRIMSON survey I: super-stellar SiO in the directly imaged companion TWA 5 B from high-resolution M-band spectroscopy
Luke T. Parker, Jayne L. Birkby, Siddharth Gandhi +4
Silicon is a key refractory element in giant planet atmospheres, which governs the formation of magnesium-silicate clouds, and reflects the quantity of silicates accreted during fo…
Mantle Convection and Nightside Volcanism on Lava World K2-141 b
Tobias G. Meier, Claire Marie Guimond, Raymond T. Pierrehumbert +13
Ultra-short period lava worlds offer a unique window into the coupled evolution of planetary interior and atmospheres under extreme irradiation. In this study, we investigate the m…
A persistent bow shock in a diskless magnetised accreting white dwarf
Krystian Ilkiewicz, Simone Scaringi, Domitilla de Martino +9
Stellar bow shocks are formed when an outflow interacts with the interstellar medium. In white dwarfs accreting from a binary companion, outflows are associated with either strong…
No TiO detected in the hot Neptune-desert planet LTT-9779 b in reflected light at high spectral resolution
Sophia R. Vaughan, Jayne L. Birkby, Natasha E. Batalha +12
LTT-9779 b is an inhabitant of the hot Neptune desert and one of only a few planets with a measured high albedo. Characterising the atmosphere of this world is the key to understan…
Chasing the storm: Investigating the application of high-contrast imaging techniques in producing precise exoplanet light curves
Ben J. Sutlieff, David S. Doelman, Jayne L. Birkby +10
Substellar companions such as exoplanets and brown dwarfs exhibit changes in brightness arising from top-of-atmosphere inhomogeneities, providing insights into their atmospheric st…
