Kepler-7 b is a gas giant exoplanet that orbits a G-type star. Its mass is 0.441 Jupiters, it takes 4.9 days to complete one orbit of its star, and is 0.06067 AU from its star. Its discovery was announced in 2009.
10 Οκτ 2024 · Kepler-7 b is a Confirmed extrasolar planet (exoplanet) that orbits the star Kepler 7 in the constellation of Lyra
Kepler-7 is the largest host star of the first five planets detected by Kepler, and is situated in the Lyra constellation. The star has a radius 184% that of the Sun. Kepler-7 also has 135% the Sun's mass, and thus is larger and more massive (though less dense) than the Sun.
30 Μαρ 2010 · We report on the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, MP = 0.43 MJ, but the radius is 50% larger, RP = 1.48 RJ. The resulting density, ρ P = 0.17 g cm −3, is the second lowest reported so far for an extrasolar planet.
[length] → a (semimajor axis) [mass] → M [speed] → Ω K a [time] → 1/Ω K where Ω K ≡ GM/r3. The time steps can be made either fixed (e.g., some small fraction of 1/Ω K), or variable, depending on how rapidly the motion is changing. One possible variable timestep scheme is: r r 1 − r 2 Δt = ξ | | or ξ | | , (8)
Consider a modi cation of the standard map. pn+1 = pn + K sin n + bn+1 = n + pn + K sin n. (1) The parameter b can be considered a drift rate. Note: You can consider this map or you can consider the map. pn+1 = pn + K sin n + b. n+1 = n + pn + K sin n + b. (2) you substitute p.
The simple thin-lens model of the keplerian telescope can be extended to systems composed of two real focusing lenses if we know their focal lengths and the location of each lens’ front and...
