Searching for planets in the Hyades. V. Limits on planet detection in the presence of stellar activity.

PAULSON D.B., COCHRAN W.D. and HATZES A.P.

Abstract (from CDS):

We present the results of a radial velocity survey of a sample of Hyades stars and discuss the effects of stellar activity on radial velocity measurements. The level of radial velocity scatter due to rotational modulation of stellar surface features for the Hyades is in agreement with the 1997 predictions of Saar & Donahue–the maximum radial velocity rms of up to ∼50 m/s, with an average rms of ∼16 m/s. In this sample of 94 stars we find one new binary, two stars with linear trends indicative of binary companions, and no close-in giant planets. We discuss the limits on extrasolar planet detection in the Hyades and the constraints imposed on radial velocity surveys of young stars.
