Observing simulated Cepheid variable stars in an introductory astronomy lab

American Journal of Physics, 1979
An astronomy laboratory exercise has been developed which allows students to discover for themselves the relationship between the temperature and luminosity changes in Cepheid variable stars. The equipment used is either easily constructed or readily available from among instruments commonly found in physics departments.

A distance to the galaxy NGC4258 from observations of Cepheid variable stars

Nature, 1999
Cepheid variable stars pulsate in a way that is correlated with their intrinsic luminosity, making them useful as 'standard candles' for determining distances to galaxies; the potential systematic uncertainties in the resulting distances have been estimated to be only 8-10%.

Spectra of Population II Cepheid Variable Stars

1958
The physical properties of the population II cepheids have been studied using the following material: photoelectric observations of Arp, low dispersion spectra of Joy, high dispersion spectra taken by Sanford and Abt, and numerous moderate dispersion spectra obtained by the author. Radial velocity curves for ten cepheids are shown.
