| Abstract: | The LOFAR mission announced the detection of a radio emission coming from the M dwarf GJ 1151 which is consistent with the possible interaction of the star with an Earth-like exoplanet with an orbit of 1 to 5 d. Combining new data from different radial velocity surveys we calculate a new upper limit on the minimum mass of this possible companion at 0.9 M⊕ to 1.6 M⊕ for a 1.02 d to 5 d orbit. We also find evidence of a Neptune-like companion with a minimum mass of 10.6 ± 1.5 M⊕ on a 396 ± 6 d circular orbit and a likely more massive Neptunian exoplanet with a minimum mass of 24 ± 1.5 M⊕ on a 2093+130 d keplerian orbit. |
