September 2023 News and research papers
Hi Folks
Please find this month’s news items and research papers below along with the attached starcharts.
If I had to pick a personal highlight it was the renewed search for a potential planet in the Juiper belt along with stars from Andromeda and exoplanets too.
Cheers Edwin

Is There an Earth-like Planet in the Distant Kuiper Belt?
The search in the outer solar system takes a new turn with new research here.
With everything going on, I was wondering when things were at with the search in the outer Solar system, The Vera Rubin should provide some amazing results.
It sounds like our proposed "Planet 9" has gone from a mini Neptune to a super Earth type planet on a closer orbit. I'll have to read and digest the paper
