Scientific paper

It is noted that the star HZ 9, a member of the Hyades, is a
spectroscopic binary with a period of 0.56433 day. One component is a DA
white dwarf and the other is a late main-sequence M star (roughly
dM4.5e). The system is similar to V471 Tauri and PG 1413+01; like them,
it is probably a post-common-envelope binary.
