Scientific paper

Observational data in the uvby-beta-photometric system are presented for LkH-alpha 264, T Tau, RW Aur, Brun 276, NGC 2264 W108, and AS 501. Preliminary computations of temperatures and total luminosities locate these variable stars above the ZAMS. The c(1) index for T Tau stars is very peculiar, and the m(1) index is abnormal. These indices are different from the values found for other kind of stars; they may thus be used to identify faint and/or extragalactic T Tau stars.
