<egg|zzz|egg> bofh: we're having trouble finding an initial state for the TRAPPIST-1 system
<egg|zzz|egg> bofh: papers seem to give ensemble means from MCMC or whatever, rather than a particular state
<egg|zzz|egg> bofh: do we need to do MCMC ourselves :-/
<kmath> <rmayoff> @ubsanitizer Hot take: `🐱` is the natural choice for concatenation. Also, gonna go with `🤐` for the zip function.
<bofh> egg|zzz|egg: can't you just pick a random initial state which lies on each orbit?
<egg|zzz|egg> bofh: what do you mean
<bofh> like just any initial state that's not invalid should work, no?
<UmbralRaptop> exact alignment being off can do back things via resonances, right? *eyes Jool*
<UmbralRaptop> Maybe pick an alignment based on transit times?
<egg|zzz|egg> bofh: define "work"
<egg|zzz|egg> bofh: also define "invalid"
<egg|zzz|egg> UmbralRaptop: I mean, yes, using the observations to get a state would work, also it entails doing what they did in the paper, some sort of MCMC fancy thing
<egg|zzz|egg> or is that МCMC
<egg|zzz|egg> !u МCMC

<UmbralRaptop> hrm
<UmbralRaptop> ;8ball 🔪 papers that don't include epoch in their orbital elements?
<kmath> UmbralRaptop: Very doubtful
<UmbralRaptop> And yes, making the first M Cyrillic is very Principia.

<egg|zzz|egg> UmbralRaptop: I think it's not just an epoch, it's also that it's some sort of ensemble mean so probably not as a specific system state?
<bofh> egg|zzz|egg: any initial state that is observationally possible. i.e. the planets are all on their elliptical orbits that coincide with the mean motion elements?
<bofh> I mean surely we have apsides for TRAPPIST-1
<egg|zzz|egg> observationally possible means you get the same transit timings
<egg|zzz|egg> which you can do, but that's a big nasty optimization problem on the initial state
<egg|zzz|egg> hence the MCMC
<egg|zzz|egg> s/M/М/
<Qboid> egg|zzz|egg meant to say: hence the МCMC
<bofh> and by "not invalid" I mean ones for which when you then run the ensemble, it doesn't wildly diverge at any forward point Bop/Jool style
Technicalfool_ has quit [Ping timeout: 198 seconds]
<egg|zzz|egg> you can get a state that has roughly the right periods, but is distinguishable from the real thing by TTV
<egg|zzz|egg> and, well, then it's not the real thing :-p
<egg|zzz|egg> but finding elements by TTV requires doing TTV analysis, and we're lazy
Technicalfool has joined #kspacademia
<bofh> so IMHO all that's necessary is the periods being correct respective to each other :P
<egg|zzz|egg> yes but how correct
<bofh> as in the resonances are stable and constant
