PPT-Photometry : The measurement of the intensity, brightness, or other properties of light.

Photonssec Count Photons Sounds simple but what if the measuring equipment misses some because it is not 100 efficient what if the atmosphere or telescope dont transmit all of the photons. Richard W. Schmude, Jr. . Gordon State College. Overview. Introduction. Materials and method. Results. Discussion and conclusions. Purpose of work. No previous measurements for the brighter planets for J and H. USNO-B1 1289-0181948. Blake Head. What is a Variable Star?. A variable star is simply a star that changes in brightness over a set period of time (generally). This can happen in eclipsing binaries, where a star passes in front of another companion star, and pulsating variables, in which a star physically pulsates inwards and out due to instabilities within its core. .
