Global Gravitationally-Organized Spiral Waves and the Structure of NGC 5247
S. A. Khoperskov, A. V. Khoperskov, I. S. Khrykin +5
Using observational data, we build numerical N-body, hydrodynamical and combined equilibrium models for the spiral galaxy NGC 5247. The models turn out to be unstable towards spira…
The Metallicity Distribution Function of Omega Centauri
Peter M. Frinchaboy, Jaehyon Rhee, James C. Ostheimer +7
We explore the metallicity distribution function (MDF) of red giant stars in Omega Centauri from a catalogue of Washington M, T_2 and DDO51 photometry covering over 1.1 deg^2 outsi…
A Possible Optical Counterpart for the Triple Pulsar System PSR B1620-26
C. D. Bailyn, E. P. Rubenstein, T. M. Girard +3
We have searched deep optical images of the globular cluster M4 for a possible optical counterpart for the third body in the PSR B1620-26 system. We identify as a possible optical…
