VizieR Online Data Catalog: WD binary pathways survey. V. Gaia WD+AFGK binaries (Ren+, 2020)
Abstract
We observed 93 white dwarf and A-, F-, G-, or K-type main-sequence star (WD+AFGK) candidates during 23 nights, spanning 2017-Dec-12 to 2018-Jun-27, from the Xinglong 2.16m telescope (XL216). The instrument terminal we used was the High Resolution fiber-fed Spectrograph (HRS), thus providing Echelle spectra of a 49800 resolving power for a fixed slit width of 0.19mm, and covering the ~3650-10000Å wavelength range.
Eight nights of observations (between 2017-Jul-06 and 2018-Jan-16) were carried out using the Echelle spectrograph attached to the 2.12m telescope at the San Pedro Martir Observatory in Baja California, Mexico. The corresponding resolving power is R~20000 for a slit width of 2.8", covering the 3650-7300Å wavelength range. Finally, we obtained 264 high-resolution spectra for 104 WD+AFGK candidates, each of them having at least two spectra obtained on different nights. (4 data files).- Publication:
