Physical parameters of RR Lyrae stars in NGC 6171
D. Deras, A. Arellano Ferro, S. Muneer +2
We present an analysis of VI CCD time-series photometry of the globular cluster NGC 6171. The main goal is to determine individual physical parameters for single-mode RR Lyrae star…
Variable stars in NGC 4147 revisited: RR Lyrae stars new CCD VI photometry and physical parameters
A. Arellano Ferro, F. C. Rojas Galindo, S. Muneer +1
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-estab…
Excitation mechanism of OI lines in Herbig Ae/Be stars
Blesson Mathew, P. Manoj, Mayank Narang +7
We have investigated the role of a few prominent excitation mechanisms viz. collisional excitation, recombination, continuum fluorescence and Lyman beta fluorescence on the OI line…
Period changes in the RR Lyrae stars of NGC 6171 (M107)
A. Arellano Ferro, P. Rosenzweig, A. Luna +4
Based on photometric data obtained between 1935 and 2017, diagrams were built for 22 RR Lyrae stars in the globular cluster NGC 6171, leading to the discovery of secular peri…
