A double cluster at the core of 30 Doradus
E. Sabbi, D. J. Lennon, M. Gieles +6
Based on an analysis of data obtained with the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) we report the identification of two distinct stellar populations in th…
Emission-Line Galaxies from the Hubble Space Telescope Probing Evolution and Reionization Spectroscopically (PEARS) Grism Survey. II: The Complete Sample
Nor Pirzkal, Barry Rothberg, Chun Ly +13
We present a full analysis of the Probing Evolution And Reionization Spectroscopically (PEARS) slitess grism spectroscopic data obtained with the Advanced Camera for Surveys on HST…
Proper motions and membership probabilities of stars in the region of globular cluster NGC 6809
Devesh P. Sariya, R. K. S. Yadav, A. Bellini
NGC 6809 is a luminous metal-poor halo globular cluster that is relatively easy to study due to its proximity and low concentration. Because of its high Galactic latitude (b = -23d…
Hubble Space Telescope Observations of an Outer Field in Omega Centauri: A Definitive Helium Abundance
I. R. King, L. R. Bedin, S. Cassisi +6
We revisit the problem of the split main sequence (MS) of the globular cluster omega Centauri, and report the results of two-epoch Hubble Space Telescope observations of an outer f…
The effects of differential reddening and stellar rotation on the appearance of multiple populations in star clusters: the case of Trumpler 20
I. Platais, C. Melo, S. N. Quinn +6
We present a detailed analysis of the upper main sequence of the 1.3 Gyr old open cluster Trumpler 20. High accuracy BV photometry combined with the Very Large Telescope/FLAMES med…
The Sun was not born in M 67
Barbara Pichardo, Edmundo Moreno, Christine Allen +3
Using the most recent proper-motion determination of the old, Solar-metallicity, Galactic open cluster M 67, in orbital computations in a non-axisymmetric model of the Milky Way, i…
