Planetary system architectures in the final stages of planet formation
Patricia Luppe, Zoe Roumeliotis, Sebastian Marino +18
The processes in the last stages of planet formation determine the final assembly and composition of planets. After the protoplanetary discs dissipate, a system of planets and plan…
A Misaligned Debris Disk relative to the Host Star CPD-72 2713 from JWST/NIRCam Imaging
Jingwen Zhang, Maxwell A. Millar-Blanchaer, Kellen Lawson +17
Observations of debris disks provide a valuable window to investigate the formation and evolution of planetary systems. We present high-contrast JWST/NIRCam observations of CPD-72…
The JWST Sub-Jupiters Survey: Direct Imaging Discovery of a Giant Planet and a Debris Disk Around the Young M-dwarf RX J0534.0-0221
Rodrigo Ferrer-Chavez, Jason J. Wang, Kevin Wagner +47
We present the discovery of RX J0534.0-0221 b, a giant planet orbiting an M-dwarf star in the Pictoris moving group. RX J0534 was originally observed with JWST/NIRCam in the F4…
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
We report the direct imaging discovery of a third exoplanet in the Pictoris system. We detect Pictoris d ( Pic d) in non-coronagraphic observations obtained with VLT/ERI…
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…
JWST/NIRCam 4-5 m Imaging of the Giant Planet AF Lep b
Kyle Franson, William O. Balmer, Brendan P. Bowler +23
With a dynamical mass of , the recently discovered giant planet AF Lep b is the lowest-mass imaged planet with a direct mass measurement. Its youth and spectra…
Debris disks around main-sequence stars
Tim D. Pearce
'Debris disks' are collections of small bodies around stars, such as the Asteroid Belt and Kuiper Belt in our Solar System. These disks are composed of objects smaller than planets…
Increasing planet-stirring efficiency of debris disks by "projectile stirring" and "resonant stirring"
Tyson Costa, Tim D. Pearce, Alexander V. Krivov
Extrasolar debris disks are detected by observing dust, which is thought to be released during planetesimal collisions. This implies that planetesimals are dynamically excited ("st…
The effect of sculpting planets on the steepness of debris-disc inner edges
Tim D. Pearce, Alexander V. Krivov, Antranik A. Sefilian +6
Debris discs are our best means to probe the outer regions of planetary systems. Many studies assume that planets lie at the inner edges of debris discs, akin to Neptune and the Ku…
Self-gravity of debris discs can strongly change the outcomes of interactions with inclined planets
Pedro P. Poblete, Torsten Löhne, Tim D. Pearce +1
Drastic changes in protoplanets' orbits could occur in the early stages of planetary systems through interactions with other planets and their surrounding protoplanetary or debris…
How much large dust could be present in hot exozodiacal dust systems?
T. A. Stuber, F. Kirchschlager, T. D. Pearce +3
An infrared excess over the stellar photospheric emission of main-sequence stars has been found in interferometric surveys, commonly attributed to the presence of hot exozodiacal d…
The clumpy structure of Eridani's debris disc revisited by ALMA
Mark Booth, Tim D. Pearce, Alexander V. Krivov +8
Eridani is the closest star to our Sun known to host a debris disc. Prior observations in the (sub-)millimetre regime have potentially detected clumpy structure in the disc and…
Astrometric Accelerations as Dynamical Beacons: A Giant Planet Imaged Inside the Debris Disk of the Young Star AF Lep
Kyle Franson, Brendan P. Bowler, Yifan Zhou +13
We present the direct imaging discovery of a giant planet orbiting the young star AF Lep, a 1.2 member of the 24 3 Myr Pic moving group. AF Lep was observed a…
ISPY-NACO Imaging Survey for Planets around Young stars. The demographics of forming planets embedded in protoplanetary disks
Gabriele Cugno, Timothy D. Pearce, Ralf Launhardt +11
We present the statistical analysis of a subsample of 45 young stars surrounded by protoplanetary disks (PPDs). This is the largest imaging survey uniquely focused on PPDs to date.…
Hot exozodis: cometary supply without trapping is unlikely to be the mechanism
Tim D. Pearce, Florian Kirchschlager, Gaël Rouillé +6
Excess near-infrared emission is detected around one fifth of main-sequence stars, but its nature is a mystery. These excesses are interpreted as thermal emission from populations…
Gap carving by a migrating planet embedded in a massive debris disc
Marc F. Friebe, Tim D. Pearce, Torsten Löhne
When considering gaps in debris discs, a typical approach is to invoke clearing by an unseen planet within the gap, and derive the planet mass using Wisdom overlap or Hill radius a…
Planet populations inferred from debris discs: insights from 178 debris systems in the ISPY, LEECH and LIStEN planet-hunting surveys
Tim D. Pearce, Ralf Launhardt, Robert Ostermann +11
We know little about the outermost exoplanets in planetary systems, because our detection methods are insensitive to moderate-mass planets on wide orbits. However, debris discs can…
High resolution ALMA and HST images of q Eri: an asymmetric debris disc with an eccentric Jupiter
J. B. Lovell, S. Marino, M. C. Wyatt +10
We present \textit{ALMA} 1.3 mm and 0.86 mm observations of the nearby (17.34 pc) F9V star q1 Eri (HD 10647, HR 506). This system, with age Gyr, hosts a au ra…

Tim D. Pearce, Hervé Beust, Virginie Faramaz +4
The star Fomalhaut hosts a narrow, eccentric debris disc, plus a highly eccentric companion Fomalhaut b. It is often argued that Fomalhaut b cannot have significant mass, otherwise…
