PPT-Photometry:

Estimation of analyte concentration on the basis of light absorption   Photometry Photometry is one of the most widely used analytical procedures in biochemistry For simple routine determination of small quantities of materials The principle is based on physical laws of radiant energy or light. with Narrowband FiltersDavid G.

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. .
