Abstract:
Due to their low transit probability, the long-period planets are, as
a population, only partially probed by transit surveys. Radial
velocity surveys thus have a key role to play, in particular for giant
planets. Cold Jupiters induce a typical radial velocity semi-amplitude
of 10m/s, which is well within the reach of multiple instruments
that have now been in operation for more than a decade.
We take advantage of the ongoing radial velocity survey with the
sophie high-resolution spectrograph, which continues the search
started by its predecessor elodie to further characterize the cold
Jupiter population. Methods. Analyzing the radial velocity data from
six bright solar-like stars taken over a period of up to 15 years, we
attempt the detection and confirmation of Keplerian signals.
We announce the discovery of six planets, one per system, with minimum
masses in the range 4.8-8.3Mjup and orbital periods between 200 days
and 10 years. The data do not provide enough evidence to support the
presence of additional planets in any of these systems. The analysis
of stellar activity indicators confirms the planetary nature of the
detected signals.
These six planets belong to the cold and massive Jupiter population,
and four of them populate its eccentric tail. In this respect,
HD 80869 b stands out as having one of the most eccentric orbits, with
an eccentricity of 0.862+0.028-0.018. These planets can thus
help to better constrain the migration and evolution processes at play
in the gas giant population. Furthermore, recent works presenting the
correlation between small planets and cold Jupiters indicate that
these systems are good candidates to search for small inner planets.
Description:
The files presented below contain all the radial velocity and
associated activity indicators measurements used for the detection
and the characterization of the six planets HD27969 b, HD80869 b,
HD95544 b, HD109286 b, HD115954 b and HD211403 b.
