Scientific Publications of David L. Summers

I am particularly interested in short-period chromospherically active variable stars. In addition to this, I have also worked with RR Lyrae and T Tauri type stars.

Note: Entries in bold indicate papers in which D.L. Summers was the principal investigator.
