Abstract:
The meter-per-second precision achieved by today velocimeters enables
the search for 1-10M{earth} planets in the habitable zone of cool
stars. This paper reports on the detection of 3 planets orbiting
GJ 163 (HIP19394), a M3 dwarf monitored by our ESO/HARPS search for
planets. We made use of the HARPS spectrograph to collect 150 radial
velocities of GJ 163 over a period of 8 years. We searched the RV time
series for coherent signals and found 5 distinct periodic
variabilities.We investigated the stellar activity and casted doubts
on the planetary interpretation for 2 signals.
Before more data can be acquired we concluded that at least 3 planets are
orbiting GJ 163. They have orbital periods of Pb=8.632±0.002,
Pc=25:63±0.03 and Pd=604±8 days and minimum masses
msini=10.6±0.6, 6.8±0.9, and 29±3, respectively. We hold our
interpretations for the 2 additional signals with periods P(e)=19.4
and P(f)=108 days.
Description:
We observed GJ 163 with HARPS, a spectrograph fiber-fed by the
ESO/3.6m telescope of La Silla Observatory. Our settings and
computation of radial velocities (RV) remained the same as for our GTO
program and we refer the reader to Bonfils et al.
(2013A&A...549A.109B 2013A&A...549A.109B) for a detailed description. We gathered RVs for
154 epochs spread over 2988 days (8.2 years) between UT 30 October
2003 and 04 January 2012. Table 6 (available in electronic form) lists
all RVs in the barycentric reference frame of the Solar System. Four
measurements have significantly higher uncertainties (the RVs taken at
epochs BJD=2454804.7, 2455056.9, 2455057.9 and, 2455136.8 have
uncertainties greater than twice the median uncertainty). We removed
them and perform our analysis with the remaining 150 RVs.
