M75, a Globular Cluster with a Trimodal Horizontal Branch. I. Color-Magnitude Diagram
M. Catelan, J. Borissova, F. R. Ferraro +3
Deep UBVI photometry for a large field covering the distant globular cluster M75 (NGC 6864) is presented. We confirm a previous suggestion (Catelan et al. 1998a) that M75 possesses…
Age as the Second Parameter in NGC 288 / NGC 362? I. Turnoff Ages: a Purely Differential Comparison
M. Bellazzini, F. Fusi Pecci, F. R. Ferraro +3
We present deep V,I photometry of the globular clusters NGC 288, NGC 362 and NGC 1851 obtained during a single observational run under strictly homogeneous conditions. We use the b…
Age as the Second Parameter in NGC 288/NGC 362? II. The Horizontal Branch Revisited
M. Catelan, M. Bellazzini, W. B. Landsman +3
We revisit the "second parameter" pair of globular clusters NGC 288/NGC 362 on the basis of theoretical models for red giant branch (RGB) and horizontal branch (HB) stars. The resu…
Second Parameter Effects in and between M3 and Palomar 3
M. Catelan, R. T. Rood, F. R. Ferraro
We study the globular clusters M3 and Palomar 3 as a "second parameter (2ndP) pair," showing that: i) M3 has a surprisingly strong *internal* 2ndP; ii) The dispersion in mass on th…
