AST 104 Study Guide - Final Guide: Stellar Classification, Apparent Magnitude, Horse Length
Document Summary
If i know it"s absolute magnitude and compare to its apparent magnitude, what can i determine? temperature a: distance c. luminosity, color. 17: globular cluster, open cluster, something else. 18: globular cluster, open cluster, something else, globular cluster, open cluster, something else, globular cluster, open cluster, something else, globular cluster, open cluster (two, something else. 22. the hyades open star cluster stars of spectral class a in the hyades have apparent magnitude around m = 5. That means, the hyades is 5 mags fainter than if it were at 10 parsecs. The distance to the hyades is : 5 parsecs, 10 parsecs, 100 parsecs, impossible to tell, the pleiades open star cluster stars of spectral class a in the pleiades have apparent magnitude around m = 8. The absolute magnitude of an a0 v star is about m = 0. That means, the pleiades is 8 mags fainter than if it were at 10 parsecs.
