Searching for Embedded Protoplanets with the Keck/NIRC2 Vortex Coronagraph: Confirmation of a Core-accretion Planet in the Narrow Gap of the Elias 2-24 Disk
Andrea Bernardi, Alice Zurlo, Lucas A. Cieza +8
We present high-contrast imaging observations of seven stars obtained with the Keck/NIRC2 vortex coronagraph between 2018 May and June in the and bands. All targets host…
Dynamical Analysis of the HD 169142 Planet-Forming Disk: Twelve Years of High-Contrast Polarimetry
Miles Lucas, Michael Bottom, Ruobing Dong +19
We present a dynamical analysis of the HD 169142 planet-forming disk based on high-contrast polarimetric imaging over a twelve-year observational period, offering insights into its…
Puffed-up Inner Rings and Razor-thin Outer Rings in Structured Protoplanetary Disks
Haochang Jiang, Feng Long, Enrique Macías +8
The vertical distribution of pebbles in protoplanetary disks is a fundamental property influencing planet formation, from dust aggregation to the assembly of planetary cores. In th…
VLT/ERIS observations of the V960 Mon system: a dust-embedded substellar object formed by gravitational instability?
Anuroop Dasgupta, Alice Zurlo, Philipp Weber +8
V960~Mon is an FU Orionis object that shows strong evidence of a gravitationally unstable spiral arm that is fragmenting into several dust clumps. We report the discovery of a new…
