SSP

(simple stellar population, single stellar population, single-metallicity stellar population)
(set of stars born at the same time with the same metallicity)

The abbreviation SSP ( for simple stellar population or single stellar population or single-metallicity stellar population) means stars born the same time, with the same metallicity, presumably from the same molecular cloud. These would be the stars of a particular stellar cluster. The term SSP is commonly used in models of the evolution and demographics of such groups of stars, which are used to interpret observation.
