چکیده

We present an empirical method of conversion of single-point near-infrared J, H and K measurements of fundamental mode Cepheids to mean magnitudes, using complete light curves in V or I bands. The algorithm is based on the template light curves in the near-infrared bandpasses. The mean uncertainty of the method is estimated to about 0.03 mag, which is smaller than the uncertainties obtained in other approaches to the problem in the literature.

Magnitudes of Fundamental - Mode Cepheids from Single - Epoch Observations

We present an empirical method for converting single-point near-infrared J, H, and K measurements of fundamental-mode Cepheids to mean magnitudes, using complete light curves in V or I bands. The algorithm is based on the template light curves in the near-infrared bandpasses. The mean uncertainty of the method is estimated to about 0.03 mag, which is smaller than the uncertainties obtained in o...

LMC and SMC Cepheids : combining OGLE with DENIS and 2 MASS infrared data

I cross-correlate the ogle database of Cepheids in the Large and Small Magellanic Clouds (MCs) with the second incremental release of the 2mass JHK s survey, and the denis IJK s point source catalog towards the MCs. Of the 3384 Cepheids in ogle in both Clouds, 1745 have a counterpart in the 2mass survey within an 1 radius and good-photometry in all three bands. Only 173 have a counterpart in th...

Period-luminosity Relations Derived from the Ogle-iii Fundamental Mode Cepheids

In this Paper, we have derived Cepheid period-luminosity (P-L) relations for the Large Magellanic Cloud (LMC) fundamental mode Cepheids, based on the data released from OGLE-III. We have applied an extinction map to correct for the extinction of these Cepheids. In addition to the V IW band P-L relations, we also include JHK and four Spitzer IRAC band P-L relations, derived by matching the OGLE-...

SAGE-Var: An Infrared Survey of Variability in the Magellanic Clouds

We present the first results from the SAGE-Var program, a follow on to the Spitzer legacy program Surveying the Agents of Galaxy Evolution (SAGE; Meixner et al. 2006). We obtained 4 epochs of photometry at 3.6 & 4.5μm covering the bar of the Large Magellanic Cloud (LMC) and the central region of the Small Magellanic Cloud (SMC) in order to probe the variability of extremely red sources missed b...

The Cepheid Period - Luminosity Relation ( The Leavitt Law ) at Mid - Infrared Wavelengths : IV . Cepheids in IC 1613

We present mid-infrared Period-Luminosity relations for Cepheids in the Local Group galaxy IC 1613. Using archival IRAC imaging data from Spitzer we were able to measure single-epoch magnitudes for five, 7 to 50-day, Cepheids at 3.6 and 4.5μm. When fit to the calibrating relations, measured for the Large Magellanic Cloud Cepheids, the data give apparent distance moduli of 24.29±0.07 and 24.28±0...
