VizieR Online Data Catalog: ELM Survey South. I. RVs for 6 new ELM WDs (Kosakowski+, 2020)
Abstract
We relied on photometry from the VST ATLAS DR2+DR3 (see II/350) and SkyMapper DR1 (see II/358) surveys to select blue stars with low-surface gravity. See Sections 2.1 and 2.2.
We also use Gaia DR2 (see I/345) photometry and parallax measurements to select white dwarf candidates. See Section 3. We observed 532 unique systems over 14 nights across three observing campaigns on 2017 March (NOAO Program ID: 2017A-0076), 2017 August (NOAO Program ID: 2017B-0173), and 2018 March (NOAO Program ID: 2018A-0233) using the SOAR 4.1m telescope the Goodman high throughput spectrograph, located on Cerro Pachon, Chile. We observed 134 additional systems using the Walter Baade 6.5m telescope with the MagE spectrograph, located at the Las Campanas Observatory on Cerro Manqui, Chile. We observed 12 additional systems using the Fred Lawrence Whipple Observatory (FLWO) 1.5m Tillinghast telescope with the FAST spectrograph, located on Mt. Hopkins, Arizona. Finally, We observed 31 additional systems using the MMT 6.5m telescope with the Blue Channel Spectrograph, located on Mt. Hopkins, Arizona. (7 data files).- Publication:
