Variable stars in NGC 4147 revisited: RR Lirae stars new CCD VI photometry and physical parameters
We have calculated the physical parameters of the RR Lyrae stars in the globular cluster NGC 4147 via the Fourier decomposition of their light curves, using new data and well-established semi-empirical calibrations and zero points. The mean metallicity and distance estimated using the RRc stars are...
