The contribution of dissolving star clusters to the population of ultra-faint objects in the outer halo of the Milky Way
Filippo Contenta, Mark Gieles, Eduardo Balbinot +1
In the last decade, several ultra faint objects (UFOs, ) have been discovered in the outer halo of the Milky Way. For some of these objects it is not clear whether…
Farthest Neighbor: The Distant Milky Way Satellite Eridanus II
T. S. Li, J. D. Simon, A. Drlica-Wagner +56
We present Magellan/IMACS spectroscopy of the recently-discovered Milky Way satellite Eridanus II (Eri II). We identify 28 member stars in Eri II, from which we measure a systemic…
Differences in the rotational properties of multiple stellar populations in M 13: a faster rotation for the "extreme" chemical subpopulation
M. J. Cordero, V. Hénault-Brunet, C. A. Pilachowski +3
We use radial velocities from spectra of giants obtained with the WIYN telescope, coupled with existing chemical abundance measurements of Na and O for the same stars, to probe the…
