| I notice GJ 229 too, the well-known brown dwarf host. | |

| I don’t remember if other planets have been discovered with TERRA-HARPS ? | |

| Is there an orbital solution for Gliese 229B, or is the observation time too small for that? | |

| Another thing to note here is that Proxima Centauri (GJ 551) is among the potential additional signals, with periods of 332 and 2200 days. Whether these represent planets is not clear: - Quote :
- some of these signals might be false positives caused by noise, insufficient modelling, stellar activity, and/or instrumental artefacts.

| Any planets around Proxima Centauri massive enough to create a noticeable Doppler shift can be hopefully detected this year through microlensing. | |
