Classical Cepheids in the JWST and Roman Era: A New Theoretical Framework and its Metallicity Dependence
Giulia De Somma, Marcella Marconi, Vincenzo Ripepi +7
Classical Cepheids are fundamental distance indicators that anchor the cosmic distance ladder through their Period-Luminosity, Period-Luminosity-Color, and Period-Wesenheit relatio…
Determination of [Fe/H] in Fundamental mode Classical Cepheids from Gaia DR3 light curve Fourier parameters
Roberto Molinaro, Vincenzo Ripepi, Marcella Marconi +9
Estimating the iron abundance ([Fe/H]) of Classical Cepheids (CCs) is crucial both for validating the cosmic distance scale through the Period-Luminosity relation and for tracing t…
New theoretical predictions on Type II Cepheids: towards a self consistent Pop. II distance scale
Marcella Marconi, Roberto Molinaro, Vincenzo Ripepi +7
Type II Cepheids are pulsating stars that can be used as standard candles for old stellar populations due to their characteristic Period-Luminosity and Period-Luminosity-Colour rel…
Implications of a turbulent convection model for classical Cepheids
M. Deka, F. Ahlborn, T. A. M. Braun +1
The appearance of blue loops in the evolutionary tracks of intermediate-mass core He-burning stars is essential for explaining the observed characteristics of Cepheids. The blue lo…
