Abstract:
The third data release of Gaia has provided low-resolution spectra for
∼100000 white dwarfs (WDs) that, together with the excellent
photometry and astrometry, represent an unrivalled benchmark for the
study of this population. In this work, we first built a highly
complete volume-limited sample consisting in 12718 WDs within 100pc
from the Sun. The use of Virtual Observatory Spectral energy
distribution Analyzer tool allowed us to perform an automated fitting
of their spectral energy distributions to different atmospheric
models. In particular, the use of spectrally derived
Javalambre-Physics of the Accelerating Universe Astrophysical Survey
photometry from Gaia spectra led to the classification of DA and
non-DA WDs with an accuracy >90%, tested in already spectroscopically
labelled objects. The excellent performance achieved was extended to
practically the whole population of WDs with effective temperatures
above 5500K. Our results show that while the A branch of the Gaia WD
Hertzsprung-Russell diagram is practically populated by DA WDs, the
B branch is largely formed by non-DAs (65%). The remaining 35% of DAs
within the B branch implies a second peak at ∼0.8M☉ in the DA
mass distribution. Additionally, the Q branch and its extension to
lower temperatures can be observed for both DA and non-DA objects due
to core crystallization. Finally, we derived a detailed spectral
evolution function, which confirms a slow increase of the fraction of
non-DAs as the effective temperature decreases down to 10500K, where
it reaches a maximum of 36% and then decreases for lower temperatures
down to ∼31%.
Description:
DA and non-DA spectral classification of the 100pc population of white
dwarfs from the low-resolution Gaia-DR3 spectra and the Virtual
Observatory (VO). Gaia and Simbad information were collected for the
whole catalogue of 12718 white dwarfs within 100pc from the Sun.
Spectral classification, effective temperatures, masses, and gravities
were obtained for 8150 white dwarfs with temperatures higher than 5500K.
To build the SEDs of the 100pc WD sample from public archives within
the VO, we collected data from different photometric catalogues, which
are listed in Table 2.
The new Gaia-DR3 has provided low-resolution spectra for more than
200 million sources. The spectra cover the optical to near-infrared
(near-IR) wavelength range, from 330 to 1050nm, approximately. A total
of 12342 (97% of the whole ample) WDs in our sample had Gaia
low-resolution spectra available.
