The visible spectra of three B stars - Pi Cet, 36 Lyn, and 134 TauAn identification list is presented for the visible spectra of Pi Cet (B7 V), 36 Lyn (B8 IIIp), and 134 Tau (B9 IV). Equivalent widths are measured on medium dispersion plates of 7.0 and 12.4 A/mm, and the photographic plates are digitized using a PDS 1010A microdensiometer. The effective temperature and gravity of the three stars are estimatedCrivellari, L. et al.

Structure of the 5-minute solar oscillations - 1976-1980The discrete structure in the 5 min velocity oscillations of the solar surface has been confirmed by a re-analysis of data obtained between 1976 and 1979, and in addition a preliminary analysis of 1980 data show excellent consistency of the determined frequencies over the five year period. It is further shown that atmospheric transparency, asClaverie, A. et al.

Rapid rotation of the solar interiorEvidence for the rapid internal rotation of the sun obtained from Doppler shift measurements of the Fraunhofer absorption lines is reported. An improved version of the Doppler shift optical resonance spectrometer was used to record the resonantly scattered intensities corresponding to the two wings of the 769.9-nm Fraunhofer absorption lines ofClaverie, A. et al.
