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…
Cepheid Metallicity in the Leavitt Law (C-MetaLL) survey: IX. Metallicity dependence of Period-Wesenheit relations based on a homogeneous spectroscopic sample
V. Ripepi, E. Trentin, G. Catanzaro +8
The C-MetaLL project has provided homogeneous spectroscopic abundances of 290 Classical Cepheids (DCEPs) for which we have the intensity-averaged magnitudes in multiple optical and…
Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: VIII: Spectroscopic detection of rare earth dysprosium, erbium, lutetium and thorium in Classical Cepheids
E. Trentin, G. Catanzaro, V. Ripepi +11
Classical Cepheids are among the most important distance calibrators thanks to the correlation between their period and luminosity, and play a crucial role in the calibration as th…
The light curve model fitting of LMC Cepheids: MESA-RSP versus Stellingwerf's code predictions
M. Deka, M. Marconi, R. Molinaro +9
A major challenge in modeling classical Cepheids is the treatment of convection, particularly its complex interplay with pulsation. This inherently three-dimensional process is typ…
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…
The model fitting of Gaia DR3 Classical Cepheid light and radial velocity curves
R. Molinaro, M. Marconi, G. De Somma +6
Classical Cepheids are key astrophysical laboratories for studying stellar structure and evolution, and for calibrating the cosmic distance scale. Despite major progress, uncertain…
