Metallicity effects on the T(eff) scale for main sequence starsRelations are presently established among T(eff), colors, and metallicity for a sample of Population I and II F and G main-sequence stars whose physical parameters and photometric indices are well known. A comparison of these results with empirical calibrations, as well as the Yale and vandenBergh and Bell (1985) colors shows that theoreticalMartinez-Roger, C. et al.

The lithium resonance line in T Tauri starsHigh-resolution spectra provide evidence of the Li-I 6707 line in 28 of the stars, and the significance of the results is discussed. The Li-I equivalent widths are presented after correcting for continuum veiling with actual measurements of the veiling itself. Surface spots are found to have a complex effect on the width of the photospheric linesBasri, G. et al.

The connection between the low polarization quasar 3C 273 and blazarsPhotopolarimetric observations in UBVRI bands and near-infrared photometric observations of the low polarization quasar 3C 273 obtained between February 1989 and May 1990 are presented. The degree of polarization remained low (below 1 percent) for most of the observing period and generally decreased toward shorter wavelengths. In early 1990Valtaoja, L. et al.
