Tentative CO detection from WASP-33b eclipse data alone with SPIRou validates stacking ingresses/egresses and shows Doppler eclipse mapping can constrain rotation with additional observations.
Circulation models show equatorial jet strength most strongly alters Doppler shifts at ingress and egress, linearly affects mid-transit slope (secondary to rotation), and increases cross-correlation function width.
Exo-REM k26 grids with f_sed and a two-column patchy-cloud framework fit VHS 1256 b with a 60-40 thick-thin split and reproduce the 10 μm silicate feature.
Retrievals on six isolated brown dwarfs yield near-solar C/O (0.51-0.63), metallicities, and 12C/13C ratios (91-155) supporting molecular cloud fragmentation origin.
MASCARA-1b atmosphere has solar metallicity, solar C/O, 2.5x solar refractories, and 2.3x solar refractory-to-volatile ratio, consistent with accretion between soot-H2O and H2O-CO snowlines.
Confirmation of Fe I emission on MASCARA-5 b's dayside at 5.5 sigma significance using EXPRES, supporting a thermally inverted atmosphere with temperatures from ~2000 K to ~4500 K.
