Please find this month’s newsletters and Starcharts attached.
There is no shortage of interesting papers this month. The
highlights are the planets around Trappist-1 and TOI 178 two interesting
systems with resonances. There are a range of interesting news items too.
It’s been a busy few weeks so I’ll leave you to look through
the links and papers
Cheers Edwin
