Gaia Data Release 2: The first Gaia catalog of Long Period Variable candidates
Anm.: „Gaia Data Release 2 (DR2) provides a unique all-sky catalog of 550’737 variable stars, of which 151’761 are Long Period Variable (LPV) candidates with G variability amplitudes larger than 0.2 mag. About one fifth of the LPV candidates are Mira candidates, the majority of the rest being semi-regular variable candidates. For each source, G, BP and RP photometric time series are published, together with some LPV-specific attributes for the subset of 89’617 candidates with periods in G larger than 60 days. …“
