E3 Stellar Distances Ppt

E3 Stellar Distances Ppt Simonandisa. 1. the document discusses different units used to measure astronomical distances, including the astronomical unit (au), light year, and parsec. 2. it explains how parallax can be used to measure distances to stars by observing the apparent shift in position of a star relative to background objects as the earth orbits the sun. 3. Presentation on theme: "e3 – stellar distances."—. presentation transcript: 1 e3 – stellar distances. 2 parallax. 4 parallax. 5 parallax angle. 7 parallax angle p (in rads) r (=1 au) d tan p = r d. for small p, tan p ≈ p so d = r p. 8 parsec if the parallax angle is one arcsecond (1 “) the distance to the star is called a parsec.
