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…

Cepheid Metallicity in the Leavitt Law (C--MetaLL) survey: VIII. High-Resolution IGRINS Spectroscopy of 23 Classical Cepheids: Validating NIR Abundances

G. Catanzaro, A. Bhardwaj, V. Ripepi +8

Context. While most chemical abundance studies of Cepheids rely on optical spectroscopy, near-infrared (NIR) observations offer advantages in terms of reduced extinction and access…

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…

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…

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…

The VMC Survey -- LIV. Anomalous Cepheids in the Magellanic Clouds Period-Luminosity relations in the near-infrared bands

Teresa Sicignano, Vincenzo Ripepi, Marina Rejkuba +12

Anomalous Cepheids (ACs) are less studied metal-poor pulsating stars ([Fe/H]<-1.5) compared to Classical Cepheids (CCs) and RR Lyrae stars. They follow distinct Period-Luminosity (…

Spatial Age Distribution of Classical Cepheids in Spiral Galaxies: The Cases of M31 and M33

Giulia De Somma, Marcella Marconi, Vincenzo Ripepi +5

Classical Cepheids can be used as age indicators due to well-established period-age and period-age-color relations. \citet{Desomma2021} refined these relations by including a metal…

Ultra Long Period Cepheids as standard candles from Gaia to Rubin-LSST

I. Musella, S. Leccia, R. Molinaro +10

An analysis of the Ultra Long Period Cepheids (ULPs) properties could significantly contribute to understanding the Hubble constant tension, e.g. the current discrepancy between de…

The Hertzsprung progression of Classical Cepheids in the Gaia era

Marcella Marconi, Giulia De Somma, Roberto Molinaro +6

A new fine grid of nonlinear convective pulsation models for the so-called "bump Cepheids" is presented to investigate the Hertzprung progression (HP) phenomenon shown by their lig…
