Another star in this constellation is the prototype for a class of Population II, short-period, pulsating variable stars that are less luminous than Cepheids.  
The alpha star of this constellation lends its name to a class of main sequence stars with infrared excess interpreted as reradiation due to debris disks.  This constellation's beta star is the prototype for a class of ellipsoidal variables that are also eclipsing binaries.  For a time, its alpha star was used to set the zero point of the apparent magnitude scale.  Another star in this constellation is the prototype for a class of Population II, short-period, pulsating variable stars that are less luminous than Cepheids.
