Terrestrial Planet Finder Infrared TPFI

TPF-I will determine the planet's period, infrared brightness, amounts of life-related atmospheric gases (water vapor, ozone, carbon dioxide, methane, and nitrous oxide), and orbital distance, shape, and orientation. If the planet's atmosphere is transparent enough, TPF-I will determine the planet's length of day, ocean land ratio, and cloud variability. One TPF-I concept uses an array of four formation-flying, large, cooled telescopes (3 to 4 meters) flying in precise formation with...

The Global Carbon Cycle

The carbon cycle is the main process for the regulation of the atmospheric composition and climate with respect to increasing insolation. Walker et al. 17 , Berner 18 , Berner et al. 19 , Lasaga et al. 20 , von Bloh et al. 21 , and Franck et al. 22 as well as many others, investigated the so-called carbonate-silicate geochemical cycle between the atmosphere, the ocean, and the continents. The main feedback loop stabilizing the planetary climate is given by the silicate rock weathering. An...

Successive dots on the mass-specific branches are separated in time by 1 Gyr. ance window for the biological productivity was again in the range between 0 C and 100 C in order to incorporate thermophiles 57 , but for this study a linear continental growth model curve b in Fig. 11.3 was employed. In principle, it is possible to calculate the HZ for any...

Astrocentric Frame

Comparisons Between Coordinate Systems We have seen that, at least formally, the Poincare formalism is simpler and more compact than the Jacobi variables. But how does each perform in practice We have simulated the short-term orbital evolution of a co-planar system formed by a central star with m0 0.32M and two planets with masses m1 20MJup and m2 5MJup. Initial conditions were chosen such that both planets have circular orbits with semi-major axes a1 0.131 AU and a2 0.232 AU and are in...
