Concept URI PrefLabel Scope Note
http://astrothesaurus.org/uat/2109 Time domain astronomy Studying how astronomical objects change over time.
http://astrothesaurus.org/uat/2110 Blazhko effect "This is phenomenon observed in RR Lyr type stars and demonstrates as changes of the light curve on timescales longer than pulsation period. The effect was first found more than 100 years ago and its origin is still not well understood and subject of active research." https://github.com/astrothesaurus/UAT/issues/286
http://astrothesaurus.org/uat/2111 Double periodic variable stars Not to be confused with "Double-mode variable stars."
http://astrothesaurus.org/uat/2112 Blue large-amplitude pulsators "A class of pulsating variable stars with short periods. These stars are hot (hence "blue" in name) and show relatively large amplitudes. The evolutionary state of these stars is not known." https://github.com/astrothesaurus/UAT/issues/286
