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…

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…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123
JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…
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…
Viscously Stirring Particle Disks into Lorentzians and Gaussians to Infer Dynamical and Collisional Masses (ARKS XIII)
Eugene Chiang, Tim D. Pearce, Marija R. Jankovic +16
Disks (Keplerian or otherwise, particulate or fluid) are often assumed to have densities that drop off vertically as Gaussians. Recent mm-wave imaging of circumstellar debris disks…
Finding New Debris Discs at Sub-millimetre Wavelengths
Mark Booth, Patricia Luppe, Sebastian Marino +9
Debris discs reveal the architectures and dynamical histories of planetary systems. Sub-millimetre observations trace large dust grains within debris discs, revealing their bulk pr…
Resolving the terrestrial planet-forming region of HD 172555 with ALMA: I. Post-impact dust distribution
Zoe Roumeliotis, Luca Matrà, Grant M. Kennedy +5
Giant impacts between planetary embryos are a natural step in the terrestrial planet formation process and are expected to create disks of warm debris in the terrestrial regions of…
Discovery of H Emission from a Protoplanet Candidate Around the Young Star 2MASS J16120668-3010270 with MagAO-X
Jialin Li, Laird M. Close, Feng Long +32
2MASS J16120668-3010270 (hereafter 2MJ1612) is a young M0 star that hosts a protoplanetary disk in the Upper Scorpious star-forming region. Recent ALMA observations of 2MJ1612 show…
Recovering the structure of debris disks non-parametrically from images
Yinuo Han, Mark C. Wyatt, Sebastian Marino
Debris disks common around Sun-like stars carry dynamical imprints in their structure that are key to understanding the formation and evolution history of planetary systems. In thi…
Low CI/CO Abundance Ratio Revealed by HST UV Spectroscopy of CO-rich Debris Disks
Aoife Brennan, Luca Matrà, Sebastián Marino +6
The origin and evolution of CO gas in debris disks has been debated since its initial detection. The gas could have a primordial origin, as a remnant of the protoplanetary disk or…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Our Galaxy
Pamela Klaassen, Alessio Traficante, Maria T. Beltrán +38
As we learn more about the multi-scale interstellar medium (ISM) of our Galaxy, we develop a greater understanding for the complex relationships between the large-scale diffuse gas…
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…
A Primordial Origin for the Gas-Rich Debris Disks Around Intermediate-Mass Stars
Riouhei Nakatani, Neal J. Turner, Yasuhiro Hasegawa +4
While most debris disks consist of dust with little or no gas, a fraction has significant amounts of gas detected via emission lines of CO, ionized carbon, and/or atomic oxygen. Al…
An ALMA Survey of M-dwarfs in the Beta Pictoris Moving Group with Two New Debris Disc Detections
Patrick F. Cronin-Coltsmann, Grant M. Kennedy, Quentin Kral +4
Previous surveys in the far-infrared have found very few, if any, M-dwarf debris discs among their samples. It has been questioned whether M-dwarf discs are simply less common than…
Radio-continuum decrements associated to shadowing from the central warp in transition disc DoAr44
Carla Arce-Tord, Simon Casassus, William R. F. Dent +8
Warps have often been used to explain disc properties, but well characterised examples are important due to their role in disc evolution. Scattered light images of discs with centr…
Planetesimal/Debris discs
Sebastian Marino
This review chapter for young researchers presents our current understanding of debris discs. It introduces some of their basic properties and observables, and describes how we thi…
Insights into the planetary dynamics of HD 206893 with ALMA
S. Marino, A. Zurlo, V. Faramaz +8
Radial substructure in the form of rings and gaps has been shown to be ubiquitous among protoplanetary discs. This could be the case in exoKuiper belts as well, and evidence for th…
