Wind speed measurements in seven ultra-hot Jupiters decrease with temperature, consistent with magnetic drag and implying magnetic field strengths of a few gauss.
Direct pixel-level extraction of NIRISS spectra for WASP-18b followed by cross-correlation yields 4.4σ CO, 3.4σ H2O, and 7.8σ OH detections, with improved abundance constraints from subsequent retrievals.
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.
Simulations indicate that order-of-magnitude changes in TiO2 and SiO2 abundances in lava melts produce distinguishable TiO, SiO, and SiO2 features in dry lava planet emission spectra, potentially observable with 12 JWST eclipses for the brightest targets.
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.
