Stellar Distances Refined

Science News, 1966
0 THE DISTANCES to certain stars whose light output varies rhythmically in less than a day can now be determined more accurately. The yardstick used to measure stellar distances to the class of stars known as RR Lyrae has been given new precision by Dr. Robert F. Christy, professor of theoretical physics at California Institute of Technology, Pasadena.

Computational developments for distance determination of stellar groups

Journal of Astrophysics and Astronomy, 2010
In this paper, we consider a statistical method for distance determination of stellar groups. The method depends on the assumption that the members of the group scatter around a mean absolute magnitude in Gaussian distribution. The mean apparent magnitude of the members is then expressed by frequency function, so as to correct for observational ...

The Stellar Magnitudes and Distances

1987
Trigonometric parallax provides a highly accurate method of determining the distance to the nearest stars. The technique is essentially the same as the terrestrial surveying method of triangulation, in which the distance towards a point is measured by taking sightings, and measuring the angles to the point from either end of a baseline of known length.

Parallax as a Measure for Stellar Distances

1969
Distances in astronomy are usually so enormous, that they can only be measured by means of large instruments and a very careful measuring technique. We shall imitate the method of working on an enormously enlarged scale and with artificial light-sources.
