X-Ray absorption spectra of supported Pt catalysts with various Pt cluster sizes were collected between 77 and 673 K, in inert and hydrogen atmospheres. When analyzing these spectra with the standard EXAFS equation, a Pt-Pt bond contraction and a large increase in the inner potential correction were observed with increasing temperature. These errors are up to 0.08 A and 10 eV for clusters of 1 ...

A Hadamard-transform spectrometer has been used to obtain a spectrum of Jupiter from 880 cm(-1) to 770cm(-1) Three ammonia absorption features stand out at 870 cm(-1), 851 cm(-1), and 833 cm(-1). The general shape of the spectrum implies an atmosphere with a monotonically decreasing temperature profile up to the 125 K level. In addition, transmission profiles of the earth's atmosphere were take...

Hot Jupiters are new laboratories for the physics of giant planet atmospheres. Subject to unusual forcing conditions, the circulation regime on these planets may be unlike anything known in the Solar System. Characterizing the atmospheric circulation of hot Jupiters is necessary for reliable interpretation of the multifaceted data currently being collected on these planets. We discuss several f...
