H-band Light Curves of Milky Way Cepheids via Difference Imaging
نویسندگان
چکیده
We present H-band light curves of Milky Way Classical Cepheids observed as part the DEHVILS survey with Wide-Field Infrared Camera on United Kingdom InfraRed Telescope. Due to crowded nature these fields caused by defocusing Camera, we performed difference-imaging photometry modifying a pipeline originally developed analyze images from Transiting Exoplanet Survey Satellite. achieved photometric precision in line expectations photon statistics, reaching 0.01 mag for 8 <= H 11 mag. used resulting Cepheid derive corrections "mean light" random-phase Hubble Space Telescope observations F160W. find good agreement previous phase based VI literature, mean difference -1 +/- 6 millimag.

Milky Way Rotation from Cepheids
The 87 new 0 determinations were added to the existing sample of cepheids with known radial velocities, forming an extended sample of 278 galactic classical cepheids with reliable radial velocity and photometry. We then calculated distances for these objects through a Period-Luminosity-Colour relation due to Feast & Walker (1987). The position of the cepheids in the galactic disk as given by th...
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) ...

7 Globular clusters and Population II stars are fossil remnants of the first major epoch of star formation in the Milky Way. SIM Lite will determine precise distances to selected Pop II objects to define a reliable distance scale, and establish reliable absolute and relative ages. Those ages set a minimum age for the Universe and map the early formation history of the Milky Way. The resultant a...
متن کاملDetailed abundances from integrated-light spectroscopy: Milky Way globular clusters
Context. Integrated-light spectroscopy at high spectral resolution is rapidly maturing as a powerful way to measure detailed chemical abundances for extragalactic globular clusters (GCs). Aims. We test the performance of our analysis technique for integrated-light spectra by applying it to seven well-studied Galactic GCs that span a wide range of metallicities. Methods. Integrated-light spectra...
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...
