Semi-empirical Cepheid Period-luminosity Relations in Sloan Magnitudes
In this paper we derive semi-empirical Cepheid period-luminosity (P-L) relations in the Sloan ugriz magnitudes by combining the observed BV I mean magnitudes from the Large Magellanic Cloud Cepheids (LMC) and theoretical bolometric corrections. We also constructed empirical gr band P-L relations, using the publicly available Johnson-Sloan photometric transformations, to be compared with our sem...
متن کاملRebuilding the Cepheid Distance Scale I: A Global Analysis of Cepheid Mean Magnitudes
Received ; accepted – 2 – ABSTRACT We develop a statistical method for using multicolor photometry to determine distances using Cepheid variables including the effects of temperature, extinction, and metallicity and apply it to UBVRIJHK photometry of 694 Cepheids in 17 galaxies. We derive homogeneous distance, extinction and uncertainty estimates for four models, starting from the standard extr...
متن کاملPeriod-color and amplitude-color relations in classical Cepheid variables
In this paper we analyze the behavior of Galactic, LMC and SMC Cepheids in terms of period-color (PC) and amplitude-color (AC) diagrams at the phases of maximum, mean and minimum light. We find very different behavior between Galactic and Magellanic Cloud Cepheids. Motivated by the recent report of a break in LMC PC relations at 10 days (Tammann et al. 2002), we use the F-statistical test to ex...
متن کاملPeriod-colour and amplitude-colour relations in classical Cepheid variables IV: The multi-phase relations
The superb phase resolution and quality of the OGLE data on LMC and SMC Cepheids, together with existing data on Galactic Cepheids, are combined to study the period-colour (PC) and amplitude-colour (AC) relations as a function of pulsation phase. Our results confirm earlier work that the LMC PC relation (at mean light) is more consistent with two lines of differing slopes, separated at a period...
متن کاملCepheid Mass-Luminosity Relations from the Magellanic Clouds
The OGLE data base is used to obtain periods, effective temperatures and luminosities for fundamental and overtone Magellanic Cloud Cepheids. Masses are then computed for these stars with our linear code with turbulent convection assuming an average composition of (X=0.716, Z=0.010) for the LMC and of (X=0.726, Z=0.004) for the SMC. The average M–L relation for the fundamental Cepheids matches ...
