Deep VISTA observations of the Magellanic Clouds (VMCDeep)

M. -R. L. Cioni, A. O. Omkumar, N. J. G. Cross +28

The central regions of galaxies challenge observers with a high density of stars, gas and dust. The LMC hosts a dense stellar bar whereas the SMC hosts a dense core, which have elu…

Oxygen, sulfur, and iron radial abundance gradients of classical Cepheids across the Galactic thin disk

R. da Silva, V. D'Orazi, M. Palla +25

Classical Cepheids (CCs) are solid distance indicators and tracers of young stellar populations. Our aim is to provide iron, oxygen, and sulfur abundances for the largest and most…

Cepheid metallicity in the Leavitt law (C-MetaLL) survey -- III. Simultaneous derivation of the Gaia parallax offset and Period-Luminosity-Metallicity coefficients

R. Molinaro, V. Ripepi, M. Marconi +7

Classical Cepheids (DCEPs) are the most important standard candles in the extra-galactic distance scale thanks to the Period-Luminosity (), Period-Luminosity-Color ($\rm PL…

HARPS-N high spectral resolution observations of Cepheids II. The impact of the surface-brightness color relation on the Baade-Wesselink projection factor of eta Aql

N. Nardetto, W. Gieren, J. Storm +16

The Baade-Wesselink (BW) method of distance determination of Cepheids is used to calibrate the distance scale. Various versions of this method are mainly based on interferometry an…

Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: II.High-resolution spectroscopy of the most metal poor Galactic Cepheids

E. Trentin, V. Ripepi, G. Catanzaro +5

Classical Cepheids (DCEPs) are the first fundamental step in the calibration of the cosmological distance ladder. Furthermore, they represent powerful tracers in the context of Gal…
