ASTR 151 1st Edition Lecture 8 Outline of Last LectureI. 5.5 Radio AstronomyII. 5.6 InterferometryIII. 5.7 Space-Base AstronomyIV. 5.8 Full-Spectrum CoverageOutline of Current LectureI. ReviewII. Chapter 6.1III. Chapter 6.2IV. Chapter 6.3V. Chapter 6.4Current LectureI. Review of some of Chapter 5a. Diffraction – bend around corners/ edges or obstaclesb. Most telescopes use mirrors because of various reasons except reflecting telescopes aren`t affected by atmosphere muchc. Resolution is improved by using larger telescopes and shorter wavelength by using the arc equationd. Radio telescopes are useful because of observations, light admittance and radio wavesII. Chapt. 6.1 Astronomers knew of Moon, stars, mercury, Venus, Mars, Jupiter, Saturn at the timea. Eight planets were added (Uranus and Neptune)b. Kepler Belt and Oort Cloudc. More than 800 extra solar planets have been found III. Chapt. 6.2a. Distance from Sun can be found from the Kepler`s Lawsb. Orbital period can be observedc. Radius known from angular sized. Masses from Newton`s lawse. Rotation through observationThese 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.f. Density (p) = m/vg. Pluto has been proven to not be a planet; it is the largest piece of debris from the Kepler BeltIV. Chapt. 6.3a. All orbit`s are on the same plane and rotate counterclockwise except Mercuryb. Circle`s round the Sun aren`t good approximationV. Chapt. 6.4 a. Terrestriali. Mercury, Venus, Earth, and Marsii. Small, rocky, close to the Sun, rotate slowly, weak magnetic fields,and a few moonsb. Joviani. Saturn, Uranus, Neptune, and Jupiter1. Only Earth and Mars have moons2. Only Earth and Mercury has magnetic fieldsii. Has a gaseous atmosphere and violentiii. Has strong magnetic fields and
