RV and photometry of 5 M dwarfs
Listed in IVOA Registry (Virtual Observatory)
Surveys for exoplanets indicate that the occurrence rate of gas giant planets orbiting late-type stars in orbits with periods shorter than 1000 days is lower than in the case of Sun-like stars, in agreement with planet formation models based on the core/pebble accretion paradigm.
Description
The CARMENES exoplanet survey has been conducting radial-velocity observations of several targets showing long-period trends or modulations that are consistent with the presence of giant planets at large orbital separations.
We present here the analysis of five such systems that have been monitored with the CARMENES spectrograph, as well as with the IRD spectrograph. We additionally use of archival data to improve the orbital parameters of the planetary systems. We improve parameters of three previously-known planets orbiting the M dwarfs GJ 317, GJ 463, and GJ 3512.

We also determine the orbital parameters and minimum mass of the planet GJ 3512 c, for which only lower limits had been given earlier. Furthermore, we present the discovery of two new giant planets orbiting the stars GJ 9733 and GJ 508.2, although for the second one only lower limits to the orbital properties can be determined. The new planet discoveries add to the short list of known giant planets orbiting M-dwarf stars with subsolar metallicity at long orbital periods above 2000 days.
The results reveal that giant planets appear to form more frequently in wide orbits than in close-in orbits around low-mass and lower metallicity stars.
