VizieR Online Data Catalog: Abundances of 3 metal-poor stars in Horologium I (Nagasawa+, 2018)

Observations were performed using the FLAMES-UVES spectrograph on the VLT in Paranal, Chile, as part of program 096.D-0967(B) (PI: E. Balbinot) and the MIKE spectrograph at the Magellan-Clay Telescope at Las Campanas Observatory (PI: R. Bernstein). UVES observations took place on five nights over the months of 2015 December to 2016 January in 14 40-minute exposures. See section 2.1.1. MIKE observations of DES J025535-540643, a confirmed Hor I member star (Koposov+ 2015ApJ...811...62K), took place on 2016 August 06 in five 30-minute exposures. See section 2.1.2.

In Figure 1 we present a color-magnitude diagram of the confirmed (Koposov+ 2015ApJ...811...62K) and high-probability (Bechtol+ 2015ApJ...807...50B) member stars of Hor I, constructed using photometry from the Dark Energy Survey (DES; the Dark Energy Survey Collaboration 2005astro.ph.10346T).
