Metastable 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 کاملComments on claimed risk from metastable black holes
In a recent note, arXiv:0808.1415, it was argued that a hypothetical metastable black hole scenario could pose collider risk not excluded by our previous study. We comment on inconsistency of this proposed scenario. CERN-PH-TH/2008-184 August 29, 2008 [email protected] [email protected] The recent paper [1] claims to produce a scenario for LHC risk that is not excluded by our...
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...
