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!. 0. Topic: . Exoplanets. Concepts: . Infrared observations, debris disks, . exoplanet. detection, planetary systems. Missions: . Spitzer, Herschel. Coordinated by . the NASA Astrophysics . Forum. An Instructor’s Guide for using the slide sets is available at the ASP website . The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars. The milky way. (seen from Bryce Canyon, UT). The Solar System. ?. “A . system. is a set of . interacting. or interdependent. components . forming an integrated whole” (Wikipedia). The Solar System. Solar System:. The sun and all of the planets and other bodies that travel around it. Planet. A celestial body that orbits the sun, is round because of its own gravity, and has cleared the neighborhood around its orbital path. 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. The . Great Chain of Origins and Origin Hypotheses (Nebular Hypothesis). Objectives. SWBAT evaluate varying hypotheses and their evidence about the origin of the solar system. . SWBAT compare, and contrast hypotheses about the origin of our solar system. . 25.5. Any theory about the origin of the solar system must explain. why all of the planets’ orbits lie more or less in a plane . Why all of the planets orbit the sun in the same direction. . It must also explain the differences in size and composition between the terrestrial planets and the gas giants.. Ninth Edition. Neil F. Comins • William J. Kaufmann III. CHAPTER 5. Formation of the Solar System. and Other Planetary Systems. A montage of the planets in our solar system presented in correct relative sizes. The orbits in the background are also drawn to scale.. 4.1 . The Search for Origins. Goals:. Where did the solar system come from?. How did it form?. When did it form?. What properties of our solar system must a formation theory explain? . Patterns of motion of the large bodies . The Solar System. To Infinity and Beyond!. Have you ever wanted to know…. Why is the solar system called the solar system?. What makes up the solar system?. What is the solar system?. Introduction. Protoplanetary. disk: condensation and accretion. Solar wind (beginning of fusion). Collisions continue. Planetary migration (orbits shifting). Late Heavy Bombardment (Hadean Era). Planetary Evolution. Learn planetary characteristics such as number of moons, size, composition, type of atmosphere, gravity, temperature and surface features.. Understand the movement of planetary bodies.. Understand which planetary characteristics are more important than others when it relates to our understanding of other worlds. . Our solar system is ancient. . Early . astronomers believed that Earth was the center of the universe and all other heavenly bodies orbited around Earth.. Our Solar System. We now know that our sun is the center of our solar .
