- Retric 7y agoOdd to call that a gap as it’s filled with planets. At best it’s a lower density area.
- petschge 7y agoIf you check the histogram plot at exoplanet.eu (also at https://imagebin.ca/v/4hRAHBxEtEbv https://imagebin.ca/v/4hRAHBxEtEbv for your convenience) you see that the density is quite a bit lower. And "Fulton gap" is simply a better name than "Fulton's possibly lower density mass range".
- Retric 7y agoIt does look like a bimodal distribution though it’s really 3 separate groupings smooshed into two peaks. However, gap generally reserved for lower valleys ie band gap etc. So, while shorter the term is simply misleading.
- petschge 7y agoYou can get rid of the gas giant in your analysis by excluding everything further out than 0.2 AU. The distribution then separates more clearly into to peaks with a gap in between. But that is something I can not get in a minute or two in the online plotting tool. Also you should be aware that astronomy and astrophysics has quite different conventions for naming things than say condensed matter. Part of the reason is that historically they were a separate science from physics. Part of the reason is that most of the knowledge is gained from (passive) observations, not actively controlled experiments.
