Photometric and spectroscopic monitoring of T Tauri stars
Photometry from a fourth season of observing at Van Vleck Observatory is reported for several T Tauri stars. Spectra have been obtained using the Image Tube Scanner on the 40” Nickel telescope at Lick Observatory for some of these stars. Both photometric and spectroscopic observations support the spot hypothesis for the cause of the variations observed in these stars.
