Numerous population of binary Cepheids with giant companions
A bold hypothesis that outliers above the period-luminosity relation of Classical Cepheids are binaries brings a discovery of 16 new binary Cepheids with giant companions in the LMC.
The effect of metallicity on Cepheid period-luminosity relations
Metallicity is a vital parameter that impacts classical Cepheids’ luminosities. In all observed bands, metal-poor Cepheids in the SMC are intrinsically fainter than their more metal-rich counterparts in the LMC and MW.
