exoALMA XXIII. Estimating Disk and Planet Properties from Dust Morphologies with DBNets2.0
Alessandro Ruzza, Giuseppe Lodato, Giovanni Rosotti +21
The exoALMA large program provided an unprecedented view of the morphology and kinematics of 15 circumstellar disks, offering a biased but homogenous and well-characterized sample…
The Astrometric Resoeccentric Degeneracy: Eccentric Single Planets Mimic 2:1 Resonant Planet Pairs in Astrometry
Daniel A. Yahalomi, Tiger Lu, Philip J. Armitage +4
Detections of long-period giant exoplanets will expand dramatically with Gaia Data Release 4 (DR4), but interpreting these signals will require care. We derive the astrometric reso…
Fragmentation-limited dust filtration in 2D simulations of planet-disk systems with dust coagulation. Parameter study and implications for the inner disk's dust mass budget and composition
Thomas Pfeil, Philip J. Armitage, Yan-Fei Jiang
Super-thermal gas giant planets or their progenitor cores are known to open deep gaps in protoplanetary disks, which stop large, drifting dust particles on their way to the inner d…
Requirements for Joint Orbital Characterization of Cold Giants and Habitable Worlds with Habitable Worlds Observatory
Sabina Sagynbayeva, Asif Abbas, Stephen R. Kane +10
We determine optimal requirements for the joint detection of habitable-zone planets and cold giant planets with the Habitable Worlds Observatory (HWO). Analysis of 164 nearby stars…
Planet formation theory: an overview
Philip J. Armitage
The standard model for planet formation is a bottom-up process in which the origin of rocky and gaseous planets can be traced back to the collision of micron-sized dust grains with…
