The Arcturus moving group

Williams, Mary Elaine Kathleen


The Arcturus moving group is a well-populated example of phase space substructure within the disk of our Galaxy. With its large rotational lag (V = -100 km/s{u207B}{u00B9}), metal poor nature ([Fe/H] ~ -0.6) and significant age (10 Gyr) it belongs to the Galaxy's thick disk. Traditionally regarded as the remains of a dissolved open cluster, it has recently been suggested to be a remnant of a satellite accreted by our Galaxy. We undertook a high-resolution spectroscopic abundance study of...[Show more]
