Large Magellanic Cloud Near-infrared Synoptic Survey. I. Cepheid Variables and the Calibration of the Leavitt Law
We present observational details and first results of a near-infrared (JHKs) synoptic survey of the central region of the Large Magellanic Cloud using the CPAPIR camera at the CTIO 1.5-m telescope. We covered 18 sq. deg. to a depth of Ks∼16.5 mag and obtained an average of 16 epochs in each band at any given location. Our catalog contains more than 5×106 sources, including 1417 Cepheid variable...
متن کاملPeriod-color and amplitude-color relations in classical Cepheid variables III: The Large Magellanic Cloud Cepheid models
Period-colour (PC) and amplitude-colour (AC) relations are studied for the Large Magellanic Cloud (LMC) Cepheids under the theoretical framework of the hydrogen ionization front (HIF) photosphere interaction. LMC models are constructed with pulsation codes that include turbulent convection, and the properties of these models are studied at maximum, mean and minimum light. As with Galactic model...
متن کاملSpitzer SAGE survey of the Large Magellanic Cloud II: Evolved Stars and Infrared Color Magnitude Diagrams
Color–magnitude diagrams (CMDs) are presented for the Spitzer SAGE (Surveying the Agents of a Galaxy’s Evolution) survey of the Large Magellanic Cloud (LMC). IRAC and MIPS 24 μm epoch one data are presented. These data represent the deepest, widest mid–infrared CMDs of their kind ever produced in the LMC. Combined with the 2MASS survey, the diagrams are used to delineate the evolved stellar pop...
متن کاملGalaxy NGC 6822 from Near - Infrared Photometry of Cepheid Variables
We have measured near-infrared magnitudes in the J and K bands for 56 Cepheid variables in the Local Group galaxy NGC 6822 with well-determined periods and optical light curves in the V and I bands. Using the template light curve approach of Soszyński, Gieren and Pietrzyński, accurate mean magnitudes were obtained from these data which allowed us to determine with unprecedented accuracy the dis...

The ARAUCARIA project: Deep near-infrared survey of nearby galaxies. I. The distance to the Large Magellanic Cloud from K-band photometry of red clump stars ABSTRACT We have obtained deep imaging in the near-infrared J and K bands for 2 nearby fields in the bar of the LMC with the ESO NTT telescope, under exquisite seeing conditions. The K, J-K color-magnitude diagrams constructed from these da...
