PPT-K8: The Basics of Planetary Atmosphere Formation

Stars solar systems form within giant molecular clouds Requires high density dust and low temperatures to initiate gravitational collapse Most material is hydrogen and helium only a few percent is other elements. HART Laboratory for Planetary Atmospheres NASA Goddard Space Flight Center Greenbelt Maryland 20771 Received February 21 1977 revised June 20 1977 Computer simulations of the evolution of the Earths atmospheric composition and surface temperature ha Topic:. Formation of. gas giant planets. Lecture by: C.P. Dullemond. Two main theories. Gravitational instability of the gas disk. Core accretion scenario. Giant Planet Formation by. Gravitational Instability. Extra-solar planetary systems. Lecture . 16. Other theory. Tidal Hypothesis. Early attempt to explain the dichotomy of planets.. Problem?. tidal force strong enough to “draw out” a filament from stars will effectively disperse it before it could condense into planets!. What is the atmosphere?. Definition: The envelope of gases surrounding planet Earth.. Why do we need the atmosphere?. The atmosphere provides protection for the planet from objects in space and contains gasses that help sustain life..
