Radial velocities of giant M stars near the ecliptic
A search dedicated to the identification of new, dwarf and cold starsclose to the Sun has allowed us to measure the radial velocities of aset of stars of late spectral type. The stars selected were M-type starspresent in the Hipparcos Input Catalogue located in a strip of+/-20° around the Ecliptic and observables from La Silla. Our inalset contains 22 M-type stars whose radial velocities Vr havebeen measured with an accuracy of ~ 0.5 km s-1 during asingle observing run. From their velocities, parallaxes and magnitudeswe deduce that all the stars observed are red giants, with spacevelocities relative to the Sun mostly lower than 100 km s-1.Based on observations collected at the CAT telescope, European SouthernObservatory, La Silla, Chile.
