Atmospheric dynamics and cloud formation of brown dwarfs and directly imaged exoplanets.

  • Cloud radiative feedback, tropical waves, vortices, light curves in global circulation models [link].
  • Cloud radiative feedback, vortex dynamics in regional f-plane circulation models [link].
  • Cloud radiative feedback, spontaneous variability, self-maintenance in 1D models [link].
  • Jets and passive tracer (clouds, chemistry) mixing driven by convective forcing in idealized circulation models [link].

For more advanced model developments with collaborators and observations of brown dwarf atmospheres, see the Publication page.

General circulation, phase curves, and spectrum modeling of hot Jupiters

  • Effects of hydrogen dissociation/recombination on the circulation and phase curve using semi-grey circulation models [link].
  • Phase curve and spectrum modeling of ultra-hot Jupiter population using circulation models with correlated-k radiative transfer [link].

For more theory developments with collaborators and observations of transit planetary atmospheres, see the Publication page.

Circulation and phase curve of brown dwarfs around white dwarfs in extremely tight orbits

  • Effects of increasing rotation in the circulation and phase curve of tight WDBD pairs [link].
  • Interesting 3D chemical mixing leads to asymmetric light curves at the CO band, which qualitatively explains the observations of ZTF0038. [link].

For HST phase curve observations of several WDBD pairs (PI: Daniel Apai) see the Publication page. JWST cycle 3 phase curve observations of several WDBD pairs have been awarded (PI: Yifan Zhou).
