White dwarf+M dwarf binaries radial velocities
Listed in IVOA Registry (Virtual Observatory)
We present the results of a radial velocity survey of 20 white dwarf plus M dwarf binaries selected as a follow up to a Hubble Space Telescope study that aimed to spatially resolve suspected binaries.
Description
Our candidates are taken from the list of targets that were spatially unresolved with Hubble. We have determined the orbital periods for 16 of these compact binary candidates.
The period distribution ranges from 0.14 to 9.16d and peaks near 0.6d. The original sample therefore contains two sets of binaries, wide orbits (~100-1000au) and close orbits (~1-10au), with no systems found in the ~10-100au. This observational evidence confirms the bimodal distribution predicted by population models and is also similar to results obtained in previous studies.

We find no binary periods in the months to years range, supporting the post common envelope evolution scenario. One of our targets, WD 1504+546, was discovered to be an eclipsing binary with a period of 0.93d.
