found: Wikipedia, Mar. 12, 2009(A long period variable (LPV) is a type of variable star in which variations in brightness occur over long timescales of months or years. Long period variables are giant stars and brighter, from spectral class F and redwards, but most are red giants and AGB giants, meaning spectral class M, S or C. They are usually deep orange or red)

The first pulsating variable discovered was the long-period variable Mira. They are cool red giants or supergiants and have periods of months to years. Their luminosities can range from 10 to 10,000 x L[subscript Sun]. Long-period variables are further classified according to whether they exhibit regular periodicity, such as the Miras or more irregular behaviour)
