JWST/NIRCam Coronagraphic Search for Hidden Planets in the HD 163296 Protoplanetary Disk
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 […]

Circumplanetary Disks Are Rare Around Planets At Large Orbital Radii: A Parameter Survey Of Flow Morphology Around Giant Planets
We investigate how the formation and structure of circumplanetary disks (CPDs) varies with planet mass and protoplanetary disk aspect ratio. Using static mesh refinement and a near-isothermal equation of state, […]

C/O Ratios And The Formation Of Wide Separation Exoplanets
The gas and solid-state C/O ratios provide context to potentially link the atmospheric composition of planets to that of the natal disk. We provide a synthesis of extant estimates of […]

Observational Characteristics Of Circum-planetary-mass-object Disks In The Era Of James Webb Space Telescope
Recent observations have confirmed circumplanetary disks (CPDs) embedded in parental protoplanetary disks (PPDs). On the other hand, planetary-mass companions (PMCs) and planetary-mass objects (PMOs) are likely to harbor their own […]

Magnetic Field Of Gas Giant Exoplanets And Its Influence On The Retention Of Their Exomoons
We study the magnetic and tidal interactions of a gas-giant exoplanet with its host star and with its exomoons, and focus on their retention. We briefly revisit the scaling law […]
