  1. Sep 13,  · Cepheids are broken up into two classes, generally speaking—Type I or Classical Cepheids, and Type II Cepheids. Type I Cepheids are younger than Type II Cepheids, and have a more structured light curve (see Figure 2) as well.
  2. Apr 22,  · The General Catalog of Variable Stars (GCVS) is the only reference source on all known variable stars. This database is based on the electronically-readable version as distributed by the Sternberg Astronomical Institute and Institute of Astronomy (Russian Acad. Sci.), Moscow. It is the catalog of extragalactic variable stars, an updated version.
  3. Cepheids are a type of very luminous variable bladeterrorzanntegal.xyzinfo is a strong direct relationship between a Cepheid's luminosity and pulsation period. This makes Cepheids important standard candles for the galactic and extragalactic distance scales.. Cepheid variables are divided into several subclasses which exhibit clearly different masses, ages, and evolutionary histories.
  4. Feb 08,  · Interestingly, Cepheid variable stars, which are also part of the distance ladder, are only found in regions that have formed new stars, too. We cannot .

  6. In most stars, these forces are balanced over long periods, but in Cepheid variables, they seem to take turns, a bit like a mass bouncing up and down on a spring. There is a clear relationship between the period of a Cepheid variable and its absolute magnitude. The greater the period then, the greater the maximum luminosity of the star.
  7. Oct 05,  · Cepheid variables can be seen and measured to a distance of about 20 million light years, compared to a maximum distance of about 65 light years for .
  8. Cepheids are a type of variable star named after the archetype, Delta Cephei, which varies by a magnitude or so over a well defined period of days. Henrietta Leavitt () compared photographs of various parts of the sky, taken on separate occasions, to identify variable stars.
