JWST NIRCam Reveals the Largest Known M-dwarf Debris Disk Around TWA 10 and New Scattered-Light Observations of the TWA 25 Debris Disk
Katie A. Crotts, Aarynn L. Carter, Beth Biller +26
We present JWST NIRCam observations of two M-dwarf systems located in the TW Hydra association, TWA 10 and TWA 25. Both systems harbor detected debris disks in the F200W and F444W…
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…
Environmental interactions in Class II systems and their impact on the disk-planet architecture
Pedro P. Poblete, Nicolás Cuello, Tim D. Pearce +4
Protoplanetary disks evolve in clustered environments where interactions with nearby stars and interstellar gas are common. Such environmental processes, including stellar flybys a…
Fomalhaut's debris disc is not dominated by primordial Plutos
Tim D. Pearce, Torsten Löhne, Alexander V. Krivov
A key challenge in debris-disc science is that we do not know the masses of debris discs, nor the sizes of the largest debris bodies. This is because modern observations can only d…
The HR 8799 Debris Disc: Shaped by Planetary Migration and a Possible Fifth Outermost Planet
Pedro P. Poblete, Tim D. Pearce, Carolina Charalambous
Context. The HR 8799 system, hosting four giant planets between a warm and cold debris disc, and an extended dusty tail beyond, serves as an ideal laboratory for studying planetary…
Review and prospects of hot exozodiacal dust research for future exo-Earth direct imaging missions
Steve Ertel, Tim D. Pearce, John H. Debes +12
Hot exozodiacal dust is dust in the innermost regions of planetary systems, at temperatures around 1000K to 2000K, and commonly detected by near-infrared interferometry. The phenom…
