Abstract:
We present radial velocities and line bisectors for 12 giants with
high Li abundance. We report the discovery of two new planetary
systems around HD238914 and TYC3318-01333-1, reveal a binary Li-rich
giant HD181368. Although our current phase coverage is not complete,
we suggest the presence of planetary mass companions around
TYC3663-01966-1 and TYC3105-00152-1. We confirm the previous result
for BD+48 740 (Adamow et al, 2012ApJ...754L..15A 2012ApJ...754L..15A).
Description:
The spectroscopic observations used for RV measurements were made with
the 9.2 Hobby-Eberly Telescope (HET) and its High-Resolution
Spectrograph, and with the 3.58 meter Telescopio Nazionale Galileo
(TNG) and its High Accuracy Radial velocity Planet Searcher in the
North hemisphere (HARPS-N).
