| Visual multiples. VIII - 1000 MK types
A total of 1000 new classifications are given for stars brighter than B= 8.0 mag in the Aitken double star catalog. The classificationssupplement 865 classifications obtained in 1981 and 1984. Among thenewly discovered stars are 12 new Ap stars, eight Lambda Bootis stars,one Ba II star, and 60 Am stars. A detailed list of the newclassifications is given.
| TU Cassiopeiae periods and amplitudes
Light-curve observations of the double-mode Cepheid TU Cas obtained by10 different groups of observers on several photometric systems over atime span of 67 years have been carefully studied to determine thefundamental and first-overtone periods and their amplitudes on the Vmagnitude scale. The presence of a second-overtone radial pulsation isdiscussed, and it is concluded that a previous detection of this modewas spurious because of the lack of a proper zero-point correction fortwo groups of observations. It is possible that the amplitude of one ofthe two modes varies during the entire observing period, with thefundamental-mode amplitude constant at 0.69 plus or minus 0.03 and theovertone amplitude decreasing from 0.4 to 0.25 mag. If this Cepheiddisplays the two pulsation modes because it is mode switching, thisswitching time scale may be less than a few hundred years.
| Spectral types for early-type stars observed by SKYLAB
MK spectral types are presented for 246 early-type stars observed withthe S-019 ultraviolet stellar astronomy experiment on Skylab. K-linetypes are also given where applicable, and various peculiar stars areidentified. The peculiar stars include five silicon stars, a shell star,a helium-rich star, a silicon-strontium star, a chromium-europium star,and two marginal metallic-line stars.
