The measurement of rotational broadening in post-common-envelope binaries.
BLEACH J.N., WOOD J.H., SMALLEY B. and CATALAN M.S.
Abstract (from CDS):
We obtained rotation rate measurements of 34.3±3.8 km.s–1 for HZ 9 and 25.1±2.3 km.s–1 for RE J1629+780 , as measured from the Na i doublet at 8183, 8195 Å and the INM lines. In both systems there is agreement between the Vrotsin i values measured from the two regions. The value of Vrotsin i measured in HZ 9 is similar to that measured for EG UMa. This is expected, as these systems share a similar orbital period and secondary star spectral type. The measurement of Vrot sin i in RE J1629+780 indicates that this system, which lacks radial velocity shifts due to orbital motion, is a wide binary as opposed to a low-inclination system.
