SU UMa star  

Définition

  • SU Ursae Majoris stars are one of three subcategories of U Geminorum stars (dwarf novae), the others being SS Cygni stars and Z Camelopardalis stars. SU UMa stars are characterized by, in addition to normal U Gem-type outbursts (which consist of a rise from quiescence of 2 to 6 magnitudes and 1- to 3-day durations), super-outbursts. These occur once for every 3 to 10 normal outbursts, last for 10 to 18 days, and add one to two magnitudes (up to a factor of 5) in brightness over the normal maxima.
