Book 1973ordoba in connection with the celebration of the Centennial of the Cordoba Observatory; the date of foundation is October 24, 1871. He proposed that the Symposium should deal with Spectral Classification and Multicolour Photometry as seven years had elapsed since the Symposium No. 24 in Saltsj6baden

The Role of Classification of Slit Spectrogramse future. The problems are so difficult — so many subtle differences between stars that we once thought of as identical are turning up now — that we must use every effective means of attack. The present challenge is to combine these methods most effectively.

Photometric Investigation of IC 2944xtremely high. Down to visual magnitude 11.5 the cluster seems to contain only O and B stars, the majority of spectral class earlier than B3. The Fabry-Pérot measurements give evidence of high internal gas motion. Evidently the gas is thin, visible only because of the great number of hot stars..Details will be published elsewhere.

The Role of Classification of Slit Spectrogramsrophotometry, or by visual classification of spectrograms. In all cases we are trying to make direct estimates of as many physical properties of the stars as possible, and as nearly as I can judge, no one method has such exclusive advantages that it seems likely to replace all others in the immediat

Photometric Investigation of IC 2944stars also Hβ has been measured. Slit spectra of intermediate dispersion (73 Å mm.) have been made for the 40 brightest stars. Coudé spectra (12 Å mm.) have been obtained for 8 stars. Fabry-Pérot measurements have been made in 5 points within the nebulosity. The number of blue stars is shown to be e

Spectral Classification Studies of Cepheids using a Small Telescope with an Image Tube Spectrographresult of a combination of the largest available light gathering power of large telescopes with the improved sensitivity of image intensifiers. We consider here the application of image tube techniques to moderate sized telescopes; concretely, we describe the first program of spectral classification
