Discovery of the Ninth Satellite of Jupiter.
So far as the program has gone, therefore, all the evidence points to a great distance for these objects. As the spirals are undoubtedly in revolution-any other explanation of the spiral form seems impossible-r the failure to find any evidences of rotation would indicate that they must be of enormous actual size, and at enormous distances from us. At a distance of one-thousand light-years, supp...
متن کاملMetastable Black Saturns Combining Everything (1) Becomes
Black Saturns have multiple horizons and so offer a testing ground for the ideas of black hole thermodynamics. In this note, we numerically scan for phases that are in equilibrium by extremizing total entropy in the 2-dimensional moduli space of stationary, singly rotating black Saturns with fixed total mass and angular momentum. On top of the known TH = TR, ΩH = ΩR configurations, we find phas...
متن کاملPhase light curves for extrasolar Jupiters and Saturns
We predict how a remote observer would see the brightness variations of giant planets similar to those in our Solar System as they orbit their central stars. We model the geometry of Jupiter, Saturn and Saturn’s rings for varying orbital and viewing parameters. Scattering properties for the planets and rings at wavelenghts 0.6-0.7 microns are assumed to follow these observed by Pioneer and Voya...
متن کاملTwo Transiting Low Density Sub-saturns from K2
We report the discovery and confirmation of K2-24 b and c, two sub-Saturn planets orbiting a bright (V= 11.3), metal-rich ([Fe/H]= 0.42±0.04 dex) G3 dwarf in the K2 Campaign 2 field. The planets are 5.68±0.56 RÅ and 7.82±0.72 RÅ and have orbital periods of 20.8851±0.0003 days and 42.3633±0.0006 days, near the 2:1 mean-motion resonance. We obtained 32 radial velocities with Keck/HIRE...
متن کاملGaddum's Pharmacology. Ninth Edition
The ninth edition of Gaddum's Pharmacology by A.S.V. Burgen and J.F. Mitchell is a review well-suited to the medical or pharmacology student. This new edition covers the essentials of pharmacology and incorporates recent advances in areas such as the mechanism of drug receptors and neuropharmacological agents. The chapters are very brief and begin with a general description of the class of phar...
