Table 2
Multiplicity fraction (fM) for the whole population of exoplanet hosts as well as a function of stellar type (for the planet-bearing star).
| All distances | ≤500 pc | Field stars | |
|---|---|---|---|
| Full sample | 16.1% | 22.5% | 46% |
| M primaries | 9.2% | 11.8% | 35% |
| K primaries | 15.2% | 19.1% | 41% |
| G primaries | 14.6% | 24.0% | 45% |
| F primaries | 22.9% | 33.7% | 51% |
| A primaries | 23.7% | 26.7% | 69% |
Notes. We show, as a reference, the fM estimated by Raghavan et al. (2010) for field stars in the solar neighbuorhood.
