Spectroscopic binaries near the North Galactic Pole. XXI - Eight short-period binaries
Orbits based principally on radial-velocity measurements made with theHaute-Provence Coravel spectrometer are presented for eight binarysystems which include some of the faintest HD stars in the Galactic-Polefield. They are HD 103418 (which is double-lined), 105021, 108151,113169, 113323, 113650, 113714, and 116514. Their periods range from 3.7to 15.1 days. Very little else is known about any of them.
| A kinematic and abundance survey at the Galactic poles. III
A sample of 418 space velocities are examined, including 83 new valuesobtained for G5-K6 giants near the North Galactic Pole. A constantDDO-derived Fe/H abundance gradient of about -0.18 dex/kpc is found toextend to 8 kpc. The data show a continuous increase in the velocitydispersion as the distance above the Galactic plane increases and as theDDO-derived Fe/H abundance ratio decreases to -1.00. The data suggest akinematic decoupling of the thick disk and halo stars. As in the case ofthe abundance gradient, the kinematic data are shown to be consistentwith the concept of the galactic-model components. It is noted thatgiants with solar DDO-derived abundances are found only sparsely in thethick disk.
