Red giants in the Small Magellanic Cloud - I. Disc and tidal stream kinematics

Dobbie, Paul; Cole, Andrew; Subramaniam, Annapurni; Keller, Stefan

Description

We present results from an extensive spectroscopic survey of field stars in the Small Magellanic Cloud (SMC). 3037 sources, predominantly first-ascent red giants, spread across roughly 37.5 deg2, are analysed. The line-of-sight velocity field is dominated by the projection of the orbital motion of the SMC around the Large Magellanic Cloud/Milky Way. The residuals are inconsistent with both a non-rotating spheroid and a nearly face on disc system. The current sample and previous stellar and HI...[Show more]
