A New Overview of Secular Period Changes of RR Lyrae stars inM5
A. Arellano Ferro, J. A. Ahumada, N. Kains +1
Secular period variations, , in 76 RR Lyrae stars in the globular cluster M5 are analysed using our most recent CCD photometry and the historical photometric databas…
Atlas of monochromatic images of planetary nebulae
W. A. Weidmann, E. O. Schmidt, R. R. Vena Valdarenas +3
We present an atlas of more than one hundred original images of planetary nebulae (PNe). These images were taken in a narrow-band filter centred on the nebular emission of the [N I…
RR Lyrae stars and the horizontal branch of NGC 5904 (M5)
A. Arellano Ferro, A. Luna, D. M. Bramich +3
We report the distance and [Fe/H] value for the globular cluster NGC 5904 (M5) derived from the Fourier decomposition of the light curves of selected RRab and RRc stars. The aim in…
