Abstract:
Close white dwarf binaries consisting of a white dwarf and an A-, F-,
G-, or K-type main-sequence star, henceforth close WD+AFGK binaries,
are ideal systems to understand the nature of type Ia supernovae
progenitors and to test binary evolution models. In this work we
identify 775 WD+AFGK candidates from TGAS (The Tycho-Gaia Astrometric
Solution) and Gaia Data Release 2 (DR2), a well-defined sample of
stars with available parallaxes, and we measure radial velocities
(RVs) for 275 of them with the aim of identifying close binaries. The
RVs have been measured from high-resolution spectra obtained at the
Xinglong 2.16m Telescope and the San Pedro Martir 2.12m Telescope
and/or from available LAMOST DR6 (low-resolution) and RAVE DR5
(medium-resolution) spectra. We identify 23 WD+AFGK systems displaying
more than 3σ RV variation among 151 systems for which the
measured values are obtained from different nights. Our WD+AFGK binary
sample contains both AFGK dwarfs and giants, with a giant fraction
∼43%. The close binary fractions we determine for the WD+AFGK dwarf
and giant samples are ∼24% and ∼15%, respectively. We also determine
the stellar parameters (i.e., effective temperature, surface gravity,
metallicity, mass, and radius) of the AFGK companions with available
high-resolution spectra. The stellar parameter distributions of the
AFGK companions that are members of close and wide binary candidates
do not show statistically significant differences.
Description:
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.
