Research in Stellar Spectroscopy

The project involved the modification of the Carpenter nebular spectrograph to permit a wide range of applications, and its use in research on galaxies and faint stars. It also involved partial support for the construction of a stellar spectrograph for the Cassegrain focus of the 36-inch Steward telescope. One of the major tasks was the rebuilding of the instrument to use glass plates instead of film. The method is used to determine the influence of line omission upon the UBV colors of the T Tauri objects T Tau and RW Aur. Calibrated spectra of these objects were obtained using the Steward Observatory 36-inch telescope and the Carpenter F 0.8 nebular spectrograph.
