The Vmc Survey. Xix. Classical Cepheids in the Small Magellanic Cloud
The VISTA near-infrared Y JKs survey of the Magellanic System (VMC) is collecting deep Ks-band time-series photometry of pulsating variable stars hosted by the two Magellanic Clouds and their connecting Bridge. In this paper, we present Y, J, Ks light curves for a sample of 4172 Small Magellanic Cloud (SMC) Classical Cepheids (CCs). These data, complemented with literature V values, allowed us ...
متن کاملBVRIJK light curves and radial velocity curves for selected Magellanic Cloud Cepheids ⋆ , ⋆ ⋆
We present high precision and well sampled BVRIJK light curves and radial velocity curves for a sample of five Cepheids in the SMC. In addition we present radial velocity curves for three Cepheids in the LMC. The low metallicity ([Fe/H] ≈ −0.7) SMC stars have been selected for use in a Baade-Wesselink type analysis to constrain the metallicity effect on the Cepheid Period-Luminosity relation. T...
متن کاملPreliminary results for RR Lyrae stars and Classical Cepheids from the Vista Magellanic Cloud (VMC) Survey
The Vista Magellanic Cloud (VMC, PI M.R. Cioni) survey is collectingKS-band time series photometry of the system formed by the two Magellanic Clouds (MC) and the “bridge” that connects them. These data are used to build KS-band light curves of the MC RR Lyrae stars and Classical Cepheids and determine absolute distances and the 3D geometry of the whole system using the K-band period luminosity ...
متن کاملThe Light and Velocity Curves of Classical Cepheids: TheoryVersus Observation
Fourier decomposition is employed to compare observed light and velocity curves of classical Cepheids with light and velocity curves generated by two sets of hydrodynamic models-the Carson-opacity models of Vemury and Stothers (VS) and a set of models constructed with Los Alamos opacities and dynamical zoning (LOS). In spite of the fact that a number of the theoretical light and (particularly) ...
متن کاملThe VMC Survey . V . First results for Classical Cepheids ⋆
The VISTA Magellanic Cloud (VMC, PI M.-R. L. Cioni) survey is collecting deep Ks-band time-series photometry of the pulsating variable stars hosted by the system formed by the two Magellanic Clouds (MCs) and the Bridge connecting them. In this paper we present the first results for Classical Cepheids, from the VMC observations of two fields in the Large Magellanic Cloud (LMC), centred on the So...
