Extended envelopes around Galactic Cepheids
Among 45 Milky Way Cepheids, investigated in this study, 13 show near-infrared excess, which is interpreted as the presence of circumstellar envelopes.

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.
