Reconstructing Cepheid Light Curve with Fourier Techniques II: Catalogue of the Fourier Parameters for OGLE LMC Fundamental Mode Cepheids
In this paper we present a catalogue of the Fourier parameters for the light curves of Large Magellanic Cloud fundamental mode Cepheids in the OGLE database. These Fourier parameters are obtained with a simulated annealing method. The photometric data are mainly fit with 4 to 8-order Fourier expansion, though some of the long period Cepheids require up to a 12-order fit to the data.
متن کاملOn the use of Principal Component Analysis in analysing Cepheid light curves
We show how Principal Component Analysis can be used to analyse the structure of Cepheid light curves. This method is more efficient than Fourier analysis at bringing out changes in light curve shape as a function of period. Using this technique, we study the shape of fundamental and first overtone mode Cepheid light curves in the Galaxy, LMC and SMC over a wide period range. For fundamentals, ...
متن کاملThe Structural Properties of Cepheid Velocity Curves
Fourier decompositions are performed on the velocity curves of 11 classical Cepheids. The progression of curve shape with period is described in terms of combinations of the lower order Fourier coefficients. These quantities are shown to change with pulsation period in a manner similar to that already demonstrated for Cepheid light variations (Simon and Lee). We recommend further velocity obser...
متن کاملThe effects of blending on the light curve shape of Cepheids
A short analysis is presented of the effects on the cepheid light curve shape, i.e. on the Fourier parameters usually adopted for its description, of the blending of the stellar image with other close stars. The conclusion is that, within reasonable error, the effects are in general small and the Fourier decomposition is confirmed to be a useful tool for pulsation mode discrimination. A large e...
متن کاملThe anomalous Cepheid XZ Ceti
Aims. XZ Ceti is the only known anomalous Cepheid in the Galactic field. Being the nearest and brightest such variable star, a detailed study of XZ Ceti may shed light on the behaviour of anomalous Cepheids whose representatives have been mostly detected in external galaxies. Methods. CCD photometric and radial velocity observations have been obtained. The actual period and amplitude of pulsati...
