Title: The Motions of "Motionless" Stars
Abstract:
We propose to observe 14 nearby stars with low proper motions using Gemini
South and the Phoenix spectrograph, to obtain kilometer-precision radial
velocities. The 14 stars constitute the first results of a new photometric
survey for nearby stars. Many of them are apparently young, and nearly all of
them have proper motions less than the 0.18"/yr rate "of interest" adopted by
most proper motion searches.
Obtaining radial velocities for these targets will complement astrometric
observations on the CTIO 0.9m that are providing accurate trigonometric
parallaxes and proper motions, and will thus complete our kinematic studies
of these stars. Complete kinematic information will allow us to determine the
true space motions of these stars, their possible cluster memberships, and
begin to answer questions about a previously neglected population of nearby
stars - those with low proper motions.
