January 11, 2006 Lecture 07: Stellar Brightness
How do we quantify stellar brightness? This lecture introduces
the inverse square-law of apparent brightness, the relation between
Luminosity and Apparent Brightness, introduces the stellar magnitude
system, and discusses photometry and the how we measure apparent
brightness in practice. Recorded
2006 January 11 in 1008 Evans Laboratory on the Columbus campus of
The Ohio State University.

January 10, 2006 Lecture 06: The Motions of the Stars
The "fixed stars" are really in constant motion, but these motions
are too small to see with the human eye in a human lifetime. This
lecture introduces proper motions (apparent angular motion of the
stars in the sky), radial velocities (motion towards or away from
us measured using the Doppler Shift of the star's spectral lines),
and true space velocities, measured by combining three key observables:
the proper motion, radial velocity, and distance to the star. Recorded
2006 January 10 in 1008 Evans Laboratory on the Columbus campus of
The Ohio State University.

January 09, 2006 Lecture 05: Distances of the Stars
How do we measure the distances to the stars? This lecture
introduces the method of trigonometric parallaxes and the
units of the Parsec and Light Year. Recorded 2006 January 9
in 1008 Evans Laboratory on the Columbus campus of The
Ohio State University.
