Abstract:
Planetary companions of a fixed mass induce reflex motions with a
larger amplitude around lower-mass stars, which adds to making M
dwarfs excellent targets for extra-solar planet searches. The most
recent velocimeters with a stability of can detect very low-mass
planets out to the habitable zone of these stars. Low-mass small
planets are abundant around M dwarfs, and most of the known
potentially habitable planets orbit one of these cool stars.
Our M-dwarf radial velocity monitoring with HARPS on the ESO 3.6m
telescope at La Silla observatory makes a major contribution to this
sample.
We present here dense radial velocity (RV) time series for three M
dwarfs observed over ∼five years: GJ 3293 (0.42M☉), GJ 3341
(0.47M☉), and GJ 3543 (0.45M☉). We extracted these RVs
through minimum chi2 -matching of each spectrum against a stack of
all observed spectra for the same star that has a high S/N ratio. We
then compared potential orbital signals against several stellar
activity indicators to distinguish the Keplerian variations induced by
planets from the spurious signals that result from rotational
modulation of stellar surface inhomogeneities and from activity
cycles.
Description:
Based on observations made with the HARPS instrument on the ESO 3.6m
telescope under the program IDs 072.C-0488, 082.C-0718 and 183.C-0437
at Cerro La Silla (Chile).
