Yesterday we talked about triples.
It is an interesting thing that as we seem to not find any binaries in clusters, we do find triples... hmm.
First Rosemary discussed stability of triples - dynamical stability of isolated triples to internal spontaneous ejection - looking at analytic criteria for overlapping resonances to second order in the disturbing function
then Ivanova and meself talked - first Ivanova skated through the theoretical zoo of dynamically formed triples, stable and not, finishing with a teaser about 4U1820-303, then I talked about The Triple.
all on video and podcast as always.

Time to finish what we started last week.
Happy birthday to the United States! It's one of the younger countries on the planet and yet has still managed to have one of the oldest continuous systems of government. Not too shabby.
So there's another planet pulsar out there? Interesting...
That's a strange phenomenon in the universe.
