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…
Converging on the Cepheid Metallicity Dependence: Implications of Non-Standard Gaia Parallax Recalibration on Distance Measures
Louise Breuval, Gagandeep S. Anand, Richard I. Anderson +20
By comparing Cepheid brightnesses with geometric distance measures including Gaia EDR3 parallaxes, most recent analyses conclude metal-rich Cepheids are brighter, quantified as $γ\…
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…
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…
Classical Cepheid Pulsation properties in the Rubin-LSST filters
Giulia De Somma, Marcella Marconi, Santi Cassisi +8
Homogeneous multi-wavelength observations of classical Cepheids from the forthcoming Rubin-LSST have the potential to significantly contribute to our understanding of the evolution…
High-resolution Spectroscopic Metallicities of Milky Way Cepheid Standards and their impact on the Leavitt Law and the Hubble constant
Anupam Bhardwaj, Adam G. Riess, Giovanni Catanzaro +10
Milky Way Cepheid variables with accurate {\it Hubble Space Telescope} photometry have been established as standards for primary calibration of the cosmic distance ladder to achiev…
