SPECTROSCOPIC ANALYSES OF THE PARENT STARS OF EXTRASOLAR PLANETARY SYSTEM CANDIDATES

The stars 1 Cnc, CrB, 16 Cyg B, 51 Peg, 47 UMa, 70 Vir, and HD 114762 have recently been proposed to harbor planetary mass companions based on small amplitude radial velocity variations. From spectroscopic analyses we derive the following values of (Fe/H) for these stars: 0.29, 0.29, 0.06, 0.21, 0.01, 0.03, and 0.60 (all with an uncertainty of 0.06 dex), respectively; the (Fe/H) value for 16 Cyg A is 0.11. The four 51 Peg-like systems, And, Boo, 1 Cnc, and 51 Peg, have a mean (Fe/H) value of 0.25. Otherwise, the abundance patterns, expressed as (X/Fe), are approximately solar. We used Fourier analysis, supplemented by line profile syn- thesis, to derive the following v sin i values: 0:66, 2:9 +13:6
