Spectrophotometric analysis of the 5200A region for peculiar and normal stars

Original language description

Many chemically peculiar (CP) stars, especially the magnetic CP2 stars, show a flux depression at 5200A. The "Delta a" photometric System takes advantage of this characteristic to detect these objects in an efficient way. In addition, it is capable of finding metal-weak, emission-type, and shell-type objects of the upper main sequence. To compare available observations and to detect new peculiar objects, we used a spectrophotometric catalogue consisting of 1159 stars. From this catalogue, we selected 1067 objects to synthesize three different "a" indices to find the most efficient one for further observations. In addition, we extended the analysis to stars cooler than F5. We employed classical "Delta a" photometry described by Maitzen, using simulatedfilter curves, the spectrophotometric "Delta a" index by Adelman, and a modified index.
