| Abstract: |
The white dwarf (WD) population observed in magnitude-limited surveys
can be used to derive the luminosity function (LF) and mass function
(MF), once the corresponding volume corrections are employed.
However, the WD samples from which the observational LFs and MFs are
built are the result of complicated target selection algorithms.
Thus, it is difficult to quantify the effects of the observational
biases on the observed functions. The LAMOST (Large sky Area
Multi-Object fiber Spectroscopic Telescope) spectroscopic survey of
the Galactic anti-center (LSS-GAC) has well-defined selection
criteria. This is a noticeable advantage over previous surveys. Here
we derive the WD LF and MF of the LSS-GAC, and use a Monte Carlo code
to simulate the WD population in the Galactic anti-center. We apply
the well-defined LSS-GAC selection criteria to the simulated
populations, taking into account all observational biases, and perform
the first meaningful comparison between the simulated WD LFs and MFs
and the observed ones. |
