Exploring the Sagittarius Stream With SEKBO Survey RR Lyrae Stars
A sample of RR Lyrae (RRL) variables from the Southern Edgeworth-Kuiper Belt Object survey in regions overlapping the expected position of debris from the interaction of the Sagittarius (Sgr) dwarf galaxy with the Milky Way (R.A. 20 and 21.5hr; distance = 16-21kpc) has been followed up spectroscopically and photometrically. The 21 photometrically confirmed type ab RRLs in this region have 〈[Fe/H]〉 = 〈1.79 〉 0.08 on our system, consistent with the abundances found for RRLs in a different portion...[Show more]
