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…
Radiation induced warping of protostellar accretion disks
P. J. Armitage, J. E. Pringle
We examine the consequences of radiatively driven warping of accretion disks surrounding pre-main-sequence stars. These disks are stable against warping if the luminosity arises fr…
The ejection of T Tauri stars from molecular clouds and the fate of circumstellar discs
P. J. Armitage, C. J. Clarke
We investigate the evolution of circumstellar discs around T Tauri stars that are ejected from small stellar clusters within molecular clouds. In particular, we study how the inter…
Magnetic braking of T Tauri stars
P. J. Armitage, C. J. Clarke
We construct models for the rotation rates of T Tauri stars whose spin is regulated by magnetic linkage between the star and a surrounding accretion disc. Our models utilise a time…
Magnetically modulated accretion in T Tauri stars
C. J. Clarke, P. J. Armitage, K. W. Smith +1
We examine how accretion on to T Tauri stars may be modulated by a time-dependent `magnetic gate' where the inner edge of the accretion disc is disrupted by a varying stellar field…
