  • Cepheid variable - Wikipedia
    A Cepheid variable ( ˈsɛfi ɪd, ˈsiːfi - ) is a type of variable star that pulsates radially, varying in both diameter and temperature It changes in brightness, with a well-defined stable period (typically 1–100 days) and amplitude
  • Galactic Cepheid Database - University of Toronto
    We present a database of over 500 classical Cepheids in the Galaxy contained in four files The first, Positional Data, contains the equatorial and galactic coordinates of each star, and cross-references to HD and SAO numbers where they exist
  • Catalog of Cepheid Stars - Harvard University

  • Cepheid Variable Stars - Cosmic Distance Ladder - NAAP
    Cepheid variables are pulsating variable stars similar to the RR Lyraes mentioned earlier on the distance modulus page However, Cepheids have longer pulsation periods and they are larger stars Cepheids have been extremely important as distance indicators for many years
  • Cepheids - NASA
    Cepheids, also called Cepheid Variables, are stars which brigthen and dim periodically This behavior allows them to be used as cosmic yardsticks out to distances of a few tens of millions of light-years
  • Cepheid Variable Stars - HyperPhysics
    Many Cepheids have periods that are known to the second according to AAVSO The Cepheid variables described above are from Population I stars and are sometimes called Type I Cepheids There is another class of variable star called a W Virginis Cepheid which is about 4 times less luminous
  • Stars, Cepheid Variable
    The approximately 400 known classical Cepheids in the Galaxy include only 17 which are well-established members of star clusters and as these are divided between 14 clusters, there are too few stars in any one cluster to study the distribution of stars in the Hertzsprung-Russell diagram
  • Cepheids database
    AIP Cepheids database Query stellar data Lists stars stars by catalog source publications authors reporting data color system formulae stellar catalogs Home Impressum
  • Cepheid Variable Stars Distance Determination
    Some types of pulsating variable stars such as Cepheids exhibit a definite relationship between their period and their intrinsic luminosity Such period-luminosity relationships are invaluable to astronomers as they are a vital method in calculating distances within and beyond our galaxy
  • Variable stars - Cepheids
    Most stars change from the swollen red giant phase to pulsating variable stars before they finally die, all reactions ceasing These are Cepheid Variables, which expand and contract, glowing brightly and fading every so often
