High-resolution stellar and interstellar spectra of HD 100340
Abstract
We present new, high-resolution, high signal-to-noise ratio, optical and 21-cm HI observations of the faint blue halo star HD 100340. A differential abundance analysis with respect to the Galactic disc star HR 2387 shows no significant peculiarities. We find that HD 100340 lies at a distance of 3 kpc, and a kinematical analysis strongly supports a `runaway star' origin. We also present improved cloud models for three intermediate velocity clouds seen in Ca II K or H I towards HD 100340.
