Metallicity of M dwarfs III. Planet-metallicity and planet-stellar mass correlations of the HARPS GTO M dwarf sample

Some interesting things coming out of the trends, particularly this:
Regarding stellar mass, we detect a positive trend in planet detections towards higher masses. However, when we take the detection limits into account, we do not find any significant difference. Therefore, the trend of the frequency of planets with the stellar mass is due to a detection bias in our sample, stressing the importance of taking into account the planet detection biases in stellar mass studies.
