The determination of fundamental stellar properties provides important information about particular groups of objects.
One such piece of information lies in the hydrogen beta index, gathered through spectral observations. The H-beta index is commonly used to measure surface temperature of stars as well as the age of stars or clusters. As such, it is a valuable piece of information for astronomical objects. In this study we present previously unpublished or updated H-beta index values for a set of delta Scuti variable stars. The original survey contained known delta Scuti stars north of -1° and brighter than 13th magnitude. This provided a sample of approximately 190 stars. Observations were made with the 1.2-m and 1.8-m telescopes at the Dominion Astrophysical Observatory.
