The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): Constraints on disk turbulence, fragmentation velocity, and inner pebble fluxes
Lilian Luo, Paola Pinilla, Camila Pulgarés +14
How substructures and disk properties affect dust evolution and the delivery of solids and volatiles into planet-forming regions remains an open question. We present results from t…
A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues
Tomohiro C. Yoshida, Felipe Alarcón, Jaehan Bae +11
Despite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseou…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): XII. Extreme millimetre variability detected in a Class II disc
James M. Miley, Laura M. Perez, Carolina Agurto-Gangas +15
Variability of millimetre wavelength continuum emission from Class II protoplanetary disks is extremely rare, and when detected it is usually interpreted as originating from non-th…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): IV. Dust and Gas Disk Properties in the Upper Scorpius Star-forming Region
Carolina Agurto-Gangas, L. M. Pérez, Anibal Sierra +18
The Atacama Large Millimeter/submillimeter Array (ALMA) large program AGE-PRO explores protoplanetary disk evolution by studying gas and dust across various ages. This work focuses…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): II. Dust and Gas Disk Properties in the Ophiuchus Star-forming Region
Dary A. Ruíz-Rodríguez, Camilo González-Ruilova, Lucas A. Cieza +17
The ALMA survey of Gas Evolution in PROtoplanetary disks (AGE-PRO) Large Program aims to trace the evolution of gas disk mass and size throughout the lifetime of protoplanetary dis…
JWST/NIRCam Coronagraphic Search for Hidden Planets in the HD~163296 Protoplanetary Disk
Taichi Uyama, Luca Ricci, Marie Ygouf +10
HD~163296 is a Herbig Ae/Be star with multiple signposts of on-going planet formation on its disk, such as prominent rings and gaps, as well as kinematic features as identified by…
A Dust-Trapping Ring in the Planet-Hosting Disk of Elias 2-24
Adolfo S. Carvalho, Laura M. Perez, Anibal Sierra +12
Rings and gaps are among the most widely observed forms of substructure in protoplanetary disks. A gap-ring pair may be formed when a planet carves a gap in the disk, which produce…
High-resolution ALMA observations of compact discs in the wide-binary system Sz 65 and Sz 66
J. M. Miley, J. Carpenter, R. Booth +11
Substructures in disc density are ubiquitous in the bright extended discs that are observed with high resolution. These substructures are intimately linked to the physical mechanis…
Annular substructures in the transition disks around LkCa 15 and J1610
S. Facchini, M. Benisty, J. Bae +8
We present high resolution millimeter continuum ALMA observations of the disks around the T Tauri stars LkCa 15 and J1610. These disks host dust-depleted inner regions, possibly ca…
Spirals inside the millimeter cavity of transition disk SR 21
G. A. Muro-Arena, C. Ginski, C. Dominik +22
Hydrodynamical simulations of planet-disk interactions suggest that planets may be responsible for a number of the sub-structures frequently observed in disks in both scattered lig…
Highly structured disk around the planet host PDS 70 revealed by high-angular resolution observations with ALMA
M. Keppler, R. Teague, J. Bae +19
PDS 70b is the most robustly detected young planet imaged in the gap of a transition disk so far, found at a separation of ~195 mas (~22 au) from its host star and at a position an…
Evidence for a massive dust-trapping vortex connected to spirals: a multi-wavelength analysis of the HD~135344B protoplanetary disk
P. Cazzoletti, E. F. van Dishoeck, P. Pinilla +6
Spiral arms, rings and large scale asymmetries are structures observed in high resolution observations of protoplanetary disks, and it appears that some of the disks showing spiral…
Shadows and asymmetries in the T Tauri disk HD 143006: Evidence for a misaligned inner disk
M. Benisty, A. Juhasz, S. Facchini +13
While planet formation is thought to occur early in the history of a protoplanetary disk, the presence of planets embedded in disks, or of other processes driving disk evolution, m…
Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
M. Keppler, M. Benisty, A. Müller +123
Young circumstellar disks are of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of planet cand…
First direct detection of a polarized companion outside of a resolved circumbinary disk around CS Cha
C. Ginski, M. Benisty, R. G. van Holstein +18
In the present study we aim to investigate the circumstellar environment of the spectroscopic binary T Tauri star CS Cha. From unresolved mid- to far-infrared photometry it is pred…
