dc.descriptionRadial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the ninth set of ten close binary systems: V395 And, HS Aqr, V449 Aur, FP Boo, SW Lac, KS Peg, IW Per, V592 Per, TU UMi, FO Vir. The first three are very close, possibly detached, early-type binaries and all three require further investigation. Particularly interesting is V395 And whose spectral type is as early as B7/8 for a 0.685 day orbit binary. KS Peg and IW Per are single-line binaries, with the former probably hosting a very low mass star. We have detected a low-mass secondary in an important semi-detached system FO Vir at q=0.125+/-0.005. The contact binary FP Boo is also a very small mass-ratio system, q=0.106+/-0.005. The other contact binaries in this group are V592 Per, TU UMi and the well known SW Lac. V592 Per and TU UMi have bright tertiary companions; for these binaries, and for V395 And, we used a novel technique of the broadening functions arranged into a 2-dimensional image in phase. The case of TU UMi turned out intractable even using this approach and we have not been able to derive a firm radial velocity orbit for this binary. Three systems of this group were observed spectroscopically before: HS Aqr, SW Lac, KS Peg.
