Wikipedia Articles
- General Catalogue of Variable Stars - The General Catalogue of Variable Stars (GCVS) is a list of variable stars. Its first edition, containing 10,820 stars, was published in 1948 by the Academy of Sciences of the USSR and edited by B.
- List of variable stars - There are over 50,000 known variable stars, with more being discovered regularly, so a complete list of every single variable is impossible. The following is a list of 178 known variable stars that are well-known, bright, significant, or otherwise interesting.
- Instability strip - Instability strip is a nearly vertical region in HR diagram which is occupied by pulsating variable stars (including RR Lyrae variable, Cepheid variable, W Virginis variable, ZZ Ceti variable, RV Tauri variable, Delta Scuti variable, SX Phoenix variable and rapidly oscillating Ap stars).
- Long period variable - A long period variable is a type of variable star in which variations in brightness occur over long timescales of months or years. The term generally refers to Mira-type variable stars (slowly pulsating red giants) although there are other types of variable stars with very long periods.
- Orion variable - Orion variables are variable stars which exhibit irregular and erruptive variations in their luminosity and are typically associated with diffuse nebulae. It is thought that these are young stars which will later become regular, non-variable stars on the zero-age main sequence.
