ASTR 151 1st Edition Lecture 22 Outline of Last LectureI. Chapter 10.4II. Chapter 10.5III. Chapter 10.6IV. Chapter 10.7Outline of Current LectureV. Chapter 11.1VI. Chapter 11.2Current LectureI. Chapt. 11 Section 1 Orbital and Physical Propertiesa. India – Guru (Heavy One)b. Chinese/ Korea – wooden starc. Babylon – Mardukd. Greek – god of the sky and thunder, also known as “Jove”i. Has rings that are very smallii. It`s largest moons were discovered by Galileo (Galilean Moons)iii. Only planet where the center of mass isn`t in the center of the Sun1. Both it and the Sun orbits the same spot in the universe equallye. Mass = 1.9x 10^27kgf. Radius = 71,500kmg. Density = 1,300kg/ msh. Rotation rate – Problematic i. Jupiter has no solid surface; different parts of atmosphere rotate @ different parts of the atmosphere rotate at different ratesii. 9hr and 55min from it`s magnetic field (half of Earth`s day)i. Has Magnetic fieldj. Has 67 moons including the 4 Galilean moonsk. Has atmospherei. 75%Hydrogen, 24%Helium, and 1%OtherThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.ii. It`s rings are in the atmosphere1. Descending airl. Orbit = 0.048 degreesm. Axis tilt = 3.13 degreesn. Gravity = 2.528 grameso. Temperature depends on pressure 165Kp. Two models of theory of how they`re formedi. Shallow1. Everything happens on topii. Deep1. Everything happens beneathq. Zones hold concentrations of ammoniai. Zones are cooler and higher than beltsii. Corresponds to upwelling of airr. Oblateness – Flatness: A measure of how flattened a planet iss. Small White – Spot (Oval BA)t. Red Spot – Great Red Spoti. Persistent cyclonic storm (retrograde)ii. South of equator, 22 degrees and colder than surroundingsu. If a planet is a perfect spherei. Re=Rp in oblatenessii. Jupiter`s Re=71,494 Rp=66,855II. Chapt. 11 Section 2 Atmospherea. Hydrogen/ helium/ small patches of methaneb. No solid surface, lowest cloud layer can`t be seen by telescopes.c. Has hole in the atmosphered. Storms across the planet merge to make bigger stormse. Puts out more heat than received from the Suni. Kelvin – Helmholtz mechanism1. Means Jupiter used to be bigger and much hotter: its
