Supersonic Equatorial Jet Archives

Different scenarios of super-rotating atmospheric material. Panels a, b and c show the scenario of a homogeneously rotating planet. The purple solid line shows the velocity kernel of the material at rotation consistent with tidally locked rotation (panel b) and the resulting shape of the cross-correlation function (panel c). The turquoise dashed line shows the effect of the planet rotating approximately six times faster. Panels d, e and f show two cases of a super-rotating equatorial jet, with the poles rotating at tidally locked velocities. The difference between the two cases is the opening angle of the equatorial region (35◦ orange dashed, and 65◦ solid green). Panels g, h and i explore the case of the velocity kernel of a super-rotating equatorial jet (blue and red solid lines in panel h) with the polar region represented by the velocity kernel of super-rotating velocity (grey dash-dotted line) or tidally locked velocity (grey dotted line) but not contributing to the transmission spectrum due to muted atmospheric features, leading in both cases to only two peaks in the CCF (panel i). -- astro-ph.EP

CRIRES+ Transmission Spectroscopy of WASP-127b. Detection Of The Resolved Signatures Of A Supersonic Equatorial Jet And Cool Poles In A Hot Planet

by Keith CowingApril 20, 2024April 20, 2024

General circulation models of gas giant exoplanets predict equatorial jets that drive inhomogeneities across the planetary atmosphere. We studied the transmission spectrum of the hot Jupiter WASP-127b during one transit […]
