New spectroscopic binaries among nearby stars
Abstract
In the course of surveying a large number of nearby (~50 pc or less) stars for indicators of youth, we have discovered a number of hitherto unknown spectroscopic binaries. Here we present a list of these new binaries with pertinent data. Two of these (HD 143705 and HD 89959) have been observed six times each, and their respective radial velocity curves are discussed.
Based on observations collected at the European Southern Observatory, Chile (ESO No. 62.I-0650, 66.D-0159(A), 67.D-0236(A)).- Publication:
