SPECTROSCOPIC EVIDENCE FOR A TEMPERATURE INVERSION IN THE DAYSIDE ATMOSPHERE OF HOT JUPITER WASP-33b
We present observations of two occultations of the extrasolar planet WASP-33b using the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope, which allow us to constrain the temperature structure and composition of its dayside atmosphere. WASP-33b is the most highly irradiated hot Jupiter discovered to date, and the only exoplanet known to orbit a δ-Scuti star. We observed in spatial scan m...
متن کاملInfrared Eclipses of the Strongly Irradiated Planet Wasp-33b, and Oscillations of Its Host Star
We observe two secondary eclipses of the strongly irradiated transiting planet WASP-33b, in the Ks band at 2.15μm, and one secondary eclipse each at 3.6μm and 4.5μm using Warm Spitzer. This planet orbits an A5V δ-Scuti star that is known to exhibit low amplitude non-radial p-mode oscillations at about 0.1% semi-amplitude. We detect stellar oscillations in all of our infrared eclipse data, and a...
متن کاملTemperature inversion in long-range interacting systems.
Temperature inversions occur in nature, e.g., in the solar corona and in interstellar molecular clouds: Somewhat counterintuitively, denser parts of the system are colder than dilute ones. We propose a simple and appealing way to spontaneously generate temperature inversions in systems with long-range interactions, by preparing them in inhomogeneous thermal equilibrium states and then applying ...
متن کاملTemperature-induced inversion of allosteric phenomena.
Two instances, involving the enzymes carbamoyl-phosphate synthetase from Escherichia coli and phosphofructokinase from Bacillus stearothermophilus, respectively, are described in which increasing temperature alone causes the actions of an allosteric ligand to change from inhibition to activation. In neither case are these effects due to a change in the activation energy of the enzyme catalyzed ...
متن کاملDuality Transformations and Temperature Inversion Symmetry
We argue that the temperature inversion symmetry present in the original Casimir setup and also in other Casimir systems for which symmetrical boundary conditions are imposed is not related to the duality transformations that in the context defined in [1] are transformations relating spatial extension and temperature, and pressure and energy density. We provide an example of a Casimir system fo...
