aFrom its mass and radius (the distance across the planet) scientists can figure out the density of the planet—whether it is made of rock, gas, or a combination of the two. (TrES-2 is made up mainly of gas).[translate]
Individual: JupiterMore than 80 giant planets are known by mass and radius. Their interior structure in terms of core mass, number of layers, and composition however is still poorly known. An overview is presented about the core mass Mcore and envelope mass of metals MZ in Jupiter as ...
In subject area: Physics and Astronomy The Jeans mass is defined as the mass within a sphere of radius λJ/2. It represents the threshold mass at which self-gravity cannot be supported by the pressure gradient, leading to gravitational collapse. ...
Three sub-Jupiter-mass planets: WASP-69b & WASP-84b transit active K dwarfs and WASP-70Ab transits the evolved primary of a G4+K3 binary newly discovered sub- Jupitermass planets: WASP-69b and WASP-84b transit active K dwarfs and WASP- 70Ab transits the evolved primary of a G4+K3 ...
Answer to: A planet has a radius of about 0.85 times Earth's radius and a mass of only 0.74 times Earth's mass. Estimate the acceleration due to...
"The sun radiates uniformly in all directions. We can calculate the total amount of energy radiated by measuring the quantity of solar energy/second reaching every square meter of Earth and then multiplying that by the total surface area of a sphere with radius equal to the radius of Earth or...
A. Centrifugal instability of the jovian magnetosphere and its interaction with the solar wind. Planet. Space Sci. 22, 1501-1510 The outer regions (r > 2.3 Rj; Rj = radius of Jupiter) of the magnetosphere of Jupiter will systematically accumulate plasma. If sufficient plasma accumula... FC ...
In this paper, we present the current state-of-the-art general theory of low-mass stars and sub-stellar objects, from one solar mass to one Jupiter mass, regarding primarily their interior structure and evolution. This review is a natural complement to the previous review on the atmosphere ...
Results are presented from an analysis of the manifestations of activity of the star WASP-193 of spectral class F9 with a super-neptune-type planet. The gaseous giant WASP-193 b with a mass 0.13 times Jupiter’s mass and almost one and a half times its radius. The planet has a low ...
