Old-Aged Primary Distance Indicators

Space Science Reviews, 2018
Old-aged stellar distance indicators are present in all Galactic structures (halo, bulge, disk) and in galaxies of all Hubble types and, thus, are immensely powerful tools for understanding our Universe.

Cepheids as Distance Indicators

Annual Review of Astronomy and Astrophysics, 1987
ABSTRACT This review attempts to summarize the various ways of determining Cepheid reddenings and luminosities and the zero points of the Cepheid period‐luminosity and period‐luminosity‐color relations. The methods of determining luminosities that are discussed involve Cepheid parallaxes, Cepheid proper motions and radial velocities, Cepheids in ...

Verification of Optical Distance Indicator Accuracy

Medical Dosimetry, 1991
The purpose of the optical distance indicator, or rangefinder, is to set the patient at a certain distance from the radiotherapy source when using either fixed SSD or an isocentric technique. If the distance that is set is not accurate, then the tumor dose calculated using this distance is also incorrect.

Relation between Distance-Based Topological Indices

Journal of Chemical Information and Computer Sciences, 2000
The pi-index of the line graph of the molecular graph of an alkane is shown to be related to the pi, Harary, and reciprocal Wiener indices of that alkane. Thus a mathematical relation between several distance-based topological indices is obtained.

Novae as Distance Indicators

2003
We review the status of Novae as distance indicators. We discuss the problem of the correct calibration of the life-luminosity relationship for Galactic novae on the basis of the properties of the M31 and LMC nova populations and show that linear regressions, normally used to interpolate the Galactic data, fit M31 and LMC only as a very rough first ...

On metagalactic distance-indicators

Vistas in Astronomy, 1956
Abstract First, an historical outline is given of the “Island-Universe” conception ( Galilei , 1609), and of the development of our knowledge of the nebulae. The cosmological views of the eighteenth century are surveyed, and in particular the developments in England during the Restoration Period (1660–1700), the Augustan Age (1700–1745), and the era ...
