Beginning of ReadMe : J/A+AS/126/21 Velocities and duplicity of F-type dwarfs (Nordstroem+ 1997) ================================================================================ Radial velocities, rotations, and duplicity of a sample of early F-type dwarfs Nordstroem B., Stefanik R.P., Latham D.W., Andersen J. <Astron. Astrophys. Suppl. Ser. 126, 21 (1997)> =1997A&AS..126...21N (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, dwarfs ; Rotational velocities ; Radial velocities Keywords: methods: statistical - techniques: radial velocities - stars: binaries: spectroscopic - stars: kinematics - Galaxy: solar neighbourhood Abstract: We present new radial and rotational velocities for 595 nearby early F dwarfs, based on digital spectra cross-correlated with individually optimised synthetic template spectra. The selection of optimum templates, the determination of rotational velocities, and the extraction of velocities from the blended spectra of double-lined spectroscopic binaries are discussed in some detail. We find 170 spectroscopic binaries in the sample and determine orbits for 18 double-lined and 2 single-lined binaries, including some spectroscopic triples. 73 stars are listed with too rapid rotation to yield useful radial velocities (i.e. vsini>120km/s). We discuss the binary frequency in the sample, and the influence of unrecognised binaries on the definition of clean metallicity groups of young F dwarfs and the determination of their kinematical properties.
