Scientific paper

Published studies of high-velocity or weak-lined dwarfs have differed in concluding that the binary frequency is either substantially lower or similar to that of Population I dwarfs. The authors therefore made a new spectroscopic study with 6 times the previous measuring accuracy of 45 high-velocity FG dwarfs. They found five spectroscopic binaries with derived orbital elements, including three previously known. The resulting frequency of spectroscopic binaries with derived orbital elements is 11%±5%, which is low relative to the 20% for Population I dwarfs. In addition, ≡9%±3% of the high-velocity dwarfs have visual companions, compared with 30% for Population I dwarfs.
