Statistical equilibrium predictions of jets and spots on Jupiter.
An equilibrium statistical theory of coherent structures is applied to midlatitude bands in the northern and southern hemispheres of Jupiter. The theory imposes energy and circulation constraints on the large-scale motion and uses a prior distribution on potential vorticity fluctuations to parameterize the small-scale turbulent eddies. Nonlinearly stable coherent structures are computed by solv...
متن کاملBright spots of sustainable shark fishing
Sharks, rays and chimeras (class Chondrichthyes; herein 'sharks') today face possibly the largest crisis of their 420 million year history. Tens of millions of sharks are caught and traded internationally each year, many populations are overfished to the point where global catch peaked in 2003, and a quarter of species have an elevated risk of extinction [1-3]. To some, the solution is to simpl...
متن کاملHAT-P-5b: A JUPITER-LIKE HOT JUPITER TRANSITING A BRIGHT STAR
We report the discovery of a planet transiting a moderately bright (V = 12.00) G star, with an orbital period of 2.788491± 0.000025 days. From the transit light curve we determine that the radius of the planet is Rp = 1.257± 0.053RJup. HAT-P-5b has a mass of Mp = 1.06± 0.11MJup, similar to the average mass of previously-known transiting exoplanets, and a density of ρp = 0.66± 0.11 g cm. We find...
متن کاملSample-space bright spots removal using density estimation
Rendering images using Monte-Carlo estimation is prone to bright spots artefacts. Bright spots correspond to high intensity pixels that appear when a very low probability sample outweighs all other sample contributions. We present an average estimator that is robust to outliers, which detects and removes samples that are considered as outliers, and lead to bright spots in images computed using ...
متن کاملModeling Sar Backscattering of Bright Flows and Dark Spots on Titan
Introduction: The SAR imaging mode of the Cassini Radar instrument allows to map the surface of Titan with a high-resolution [1]. The first Cassini close flyby Ta was acquired on 26 October 2004 and revealed a complex surface, with areas of low relief and dome-like volcanic constructs, flows and sinuous channels [1]. In particular, channels and fan-like features with a strong radar backscatteri...
