Phase-resolved high-resolution spectroscopy of CoRoT-2b measures sub-synchronous rotation at 2.6-sigma significance, consistent with its western hotspot offset.
dopplerkernel parametrizes UHJ projected winds with four parameters (v_jet, sigma_jet, v_wind, phi_sink) and retrieves jet and day-to-night flows from synthetic WASP-76b K-band emission spectra generated by three GCMs.
Wind speed measurements in seven ultra-hot Jupiters decrease with temperature, consistent with magnetic drag and implying magnetic field strengths of a few gauss.
