Theoretical RR Lyrae Instability Strip from MESA-RSP Pulsation models and updated BaSTI Evolutionary Tracks

M. Deka, M. Marconi, R. Molinaro +6

RR Lyraes (RRLs) are important tracers of old stellar populations and crucial distance indicators. To complement large variability surveys such as Gaia and Rubin-LSST, the topology…

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: 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…

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…

An "alien" called Oosterhoff dichotomy?

E. Luongo, V. Ripepi, M. Marconi +4

In this letter we investigate the origin of the Oosterhoff dichotomy, considering recent discoveries related to several ancient merging events of external galaxies with the Milky W…
