<jats:title>Abstract</jats:title> <jats:p>This Letter investigates the electron heat flux instability using the radial models of the magnetic field and plasma parameters in the inner heliosphere. Our results show that both the electron acoustic wave and the oblique whistler wave are unstable in the regime with large relative drift speed (Δ<jats:italic>V</jats:italic> <jats:sub> <jats:italic>e</jats:italic> </jats:sub>) between electron beam and core populations. Landau-resonant interactions of electron acoustic waves increase the electron parallel temperature that would lead to suppressing the electron acoustic instability and amplifying the growth of oblique whistler waves. Therefore, we propose that the electron heat flux can effectively drive oblique whistler waves in an anisotropic electron velocity distribution function. This study also finds that lower-hybrid waves and oblique Alfvén waves can be triggered in the solar atmosphere, and that the former instability is much stronger than the latter. Moreover, we clarify that the excitation of lower-hybrid waves mainly results from the transit-time interaction of beaming electrons with resonant velocities <jats:italic>v</jats:italic> <jats:sub>∥</jats:sub> ∼ <jats:italic>ω</jats:italic>/<jats:italic>k</jats:italic> <jats:sub>∥</jats:sub>, where <jats:italic>ω</jats:italic> and <jats:italic>k</jats:italic> <jats:sub>∥</jats:sub> are the wave frequency and parallel wavenumber, respectively. In addition, this study shows that the instability of quasi-parallel whistler waves can dominate the regime with medium Δ<jats:italic>V</jats:italic> <jats:sub> <jats:italic>e</jats:italic> </jats:sub> at the heliocentric distance nearly larger than 10 times of the solar radius.</jats:p>

Observational Consequences of Shallow-water Magnetohydrodynamics on Hot Jupiters
A. W. Hindle; P. J. Bushby; T. M. Rogers
<jats:title>Abstract</jats:title> <jats:p>We use results of shallow-water magnetohydrodynamics to place estimates on the minimum magnetic field strengths required to cause atmospheric wind variations (and therefore westward-venturing hotspots) for a data set of hot Jupiters (HJs), including HAT-P-7b, CoRoT-2b, Kepler-76, WASP-12b, and WASP-33b, on which westward hotspots have been observationally inferred. For HAT-P-7b and CoRoT-2b our estimates agree with past results; for Kepler-76b we find that the critical dipolar magnetic field strength, over which the observed wind variations can be explained by magnetism, lies between 4 G and 19 G; for WASP-12b and WASP-33b westward hotspots can be explained by 1 G and 2 G dipolar fields, respectively. Additionally, to guide future observational missions, we identify 61 further HJs that are likely to exhibit magnetically driven atmospheric wind variations and predict these variations are highly likely in ∼40 of the hottest HJs.</jats:p>
