Dust traps and gas kinematic signatures in a crescent structure of a planet-forming disk
Greta Guidi, François Menard, Daniel J. Price +2
In the past few years, ALMA unveiled a variety of substructures (rings, spirals, crescents) in the continuum emission of most protoplanetary disks imaged at high spatial resolution…
exoALMA XXI: The Morphology and Dynamics of Vertical Flows
Myriam Benisty, Andres F. Izquierdo, Jochen Stadler +33
Vertical gas flows, such as winds and meridional circulations, are natural outcomes of protoplanetary disk processes and play a critical role in the earliest stages of planet forma…
exoALMA XIX: Confirmation of Non-thermal Line Broadening in the DM Tau Protoplanetary Disk
Caitlyn Hardiman, Christophe Pinte, Daniel J. Price +38
Turbulence is expected to transport angular momentum and drive mass accretion in protoplanetary disks. One way to directly measure turbulent motion in disks is through molecular li…
Evidence for the Keplerian orbit of a close companion around a giant star
Mats Esseldeurs, Leen Decin, Joris De Ridder +31
Close companions influence stellar evolution through tidal interactions, mass transfer, and mass loss effects. While such companions are detected around young stellar objects, main…
Asymmetric radiation in binary systems: Implications for disk evolution and chemistry
Pedro P. Poblete, Nicolás Cuello, Antoine Alaguero +4
Current models of binary systems often depend on simplified approach of the radiation field, which are unlikely to accurately capture the complexities of asymmetric environments. W…
SPHERE/ZIMPOL insights into discs around evolved stars: arcs, asymmetries and dust properties
Kateryna Andrych, Devika Kamath, Hans Van Wincke +5
Second-generation circumbinary discs around evolved binary stars, such as post-Asymptotic Giant Branch (post-AGB) binaries, provide insights into poorly understood mechanisms of du…
