Jupiter’s atmospheric water abundance is a highly important cosmochemical parameter that linked to processes of planetary formation, weather, and circulation. Remote sensing in situ measurement attempts still leave room for substantial improvements our knowledge abundance. With the motivation advance understanding atmosphere, we investigate observations models deep clouds. We discuss clouds iso...

Physical conditions in the atmospheres of tidally locked, slowly rotating hot Jupiters correspond to dynamical circulation regimes with Rhines scales and Rossby deformation radii comparable to the planetary radii. Consequently, the large spatial scales of moving atmospheric structures could generate significant photospheric variability. Here, we estimate the level of thermal infrared variabilit...

We report 32 GHz absolute flux density measurements of the supernova remnant Cas A, with an accuracy of 2.5%. The measurements were made with the 1.5-meter telescope at the Owens Valley Radio Observatory. The antenna gain had been measured by NIST in May 1990 to be 0.505 ± 0.007 Jy . Our observations of Cas A in May 1998 yield Scas,1998 = 194± 5 Jy. We also report absolute flux density measurem...

In this paper, we make a systematic study of the global dynamical structure of the Sun– Jupiter L4 tadpole region. The results are based on long-time simulations of the Trojans in the Sun, Jupiter, Saturn system and on the frequency analysis of these orbits. We give some initial results in the description of the resonant structure that guides the long-term dynamics of this region. Moreover, we ...
