ACS photometry of newly-discovered globular clusters in the outer halo of M31
A. D. Mackey, A. Huxor, A. M. N. Ferguson +6
We report the first results from deep ACS imaging of ten classical globular clusters in the far outer regions (15 < R_p < 100 kpc) of M31. Eight of the clusters, including two of t…
Rotation and chemical abundances of Ap/Bp stars in the open cluster NGC 6475
C. P. Folsom, G. A. Wade, S. Bagnulo +1
The connection between age, rotation and chemical abundance of magnetic Ap stars is poorly understood. Using open clusters, we are able to study samples of stars that are both co-e…
ACS photometry of extended, luminous globular clusters in the outskirts of M31
A. D. Mackey, A. Huxor, A. M. N. Ferguson +6
A new population of extended, luminous globular clusters has recently been discovered in the outskirts of M31. These objects have luminosities typical of classical globular cluster…
The Possible Belts for Extrasolar Planetary Systems
Ing-Guey Jiang, M. Duncan, D. N. C. Lin
More than 100 extrasolar planets have been discovered since 1990s. Different from the solar system, these planets' orbital eccentricities cover a huge range from 0 to 0.7. Incident…
A Deep Wide-Field Variable Star Catalog of Omega Centauri
David T. F Weldrake, Penny D Sackett, Terry J Bridges
We present a variable star catalog of an extensive ground-based wide-field variability survey in the globular cluster omega Centauri. Using the ANU 40-inch (1m) telescope at Siding…
The Faint End of the Luminosity Function in the Core of the Coma Cluster
M. L. Milne, C. J. Pritchet, G. B. Poole +4
We present optical measurements of the faint end of the luminosity function in the core of the Coma cluster. Dwarf galaxies are detected down to a limiting magnitude of R approx. 2…
