Our giant paper is out about the Large inclination Distant Object (LiDO) Survey!
-
The thing I'm most proud of from this paper: the co-authors include 5 students I directly supervised for undergrad research projects and 2 I supervised for grad research projects. Not bad for a professor at a university with no astronomy major!
We've got 2 other related papers out already from the survey results. One was this beast of a pretty-plot exercise looking at stability of the plutino resonant phase space: https://iopscience.iop.org/article/10.3847/PSJ/adc10c/pdf
And one was looking at a super weird extremely distant TNO we discovered that's in the 10:1 mean-motion resonance with Neptune! It's resonances all the way out.... https://iopscience.iop.org/article/10.3847/PSJ/addd22/pdf
More soon!
Look at all the cool science we can do that will all get harder with more satellite streaks...

@sundogplanets Congratulations to everyone, and especially to you!
-
@sundogplanets very cool work! And such an excellent feeling when such long projects finally come together!
@vicgrinberg ESPECIALLY right before I have to submit a big grant proposal! "In press" sounds SO much better than "in review"

This was a stunning amount of work and took us several years (including a visit to my farm by 2 of the other co-PIs where we alternated between patting goats, keeping our children happy, and sitting at my kitchen table writing text and writing code to make pretty figures). I'm so glad it's refereed and out in the world finally!
@sundogplanets Congrats!

@sundogplanets that actually sounds like a perfect way to write a paper.
I have kids and cuddly ducks and chickens, just have to invite the coworkers

Here's our new map of the outer Solar System: we detected and tracked 141 TNOs to high precision, 62 of which are in mean-motion resonances with Neptune.
There's a tiny bit of science work testing a model of the hot classical belt orbital distribution, but we mostly want to save our science for separate papers, since this one was already SO long just with the survey and orbital classification descriptions.
@sundogplanets holy shit! actual scientists using plots that look a lot like the weirdest web app I ever built to look at asteroid data.
(Its entirely static files... don't ask if you don't want technical details. Also ignore the dead name in the footer, it shows how long its been since I updated it.)

@sundogplanets oh yes!

@hannorein My kitchen table is available for paper-writing anytime! Also my goats are happy to help with writing breaks.
@sundogplanets @hannorein when things go tits up down here can American academics escape to your farm
-
@sundogplanets congrats!
Maybe worth contacting Dr Becky on YouTube and get this study some additional reporting?

@sundogplanets kudos to persevering with data from pandemic-era observations, what a marathon! 🤯
I know it isn't the main purpose of the research, but I'm always fascinated not just by the numbers but even how big these bodies this far out can be. The Haumea-family ones y'all estimate at 30+ km (~ Arrokoth-size), maybe a few 100+km in the survey then, those with 6-7 abs magnitude? (This mpc conversion table applies to TNOs as well, right? https://minorplanetcenter.net/iau/lists/Sizes.html)

We diagnosed resonances by taking clones of the TNOs' best-fit orbits within the orbital uncertainties, and integrating them forward for 30 million years using REBOUND, then carefully looking at the resonant angle of several nearby resonances to see if it's confined - we also looked for confinement (rather than circulation) of the argument of pericentre, since that's the key for Kozai libration
Looks really cool! Something for me to think about, read about, and think some more! Fun!
One question: what are the two different phi graphs?

Congratulations! Proof that being in the hinterlands of your professional landscape can fire you up rather than put you out! (If you're made of the right stuff.)

We've got 2 other related papers out already from the survey results. One was this beast of a pretty-plot exercise looking at stability of the plutino resonant phase space: https://iopscience.iop.org/article/10.3847/PSJ/adc10c/pdf
And one was looking at a super weird extremely distant TNO we discovered that's in the 10:1 mean-motion resonance with Neptune! It's resonances all the way out.... https://iopscience.iop.org/article/10.3847/PSJ/addd22/pdf

Look at all the cool science we can do that will all get harder with more satellite streaks...
Anything there to be done with a high-fidelity optical–NIR space telescope 2030+? We're starting to look into potential science cases to be done in a first Euclid mission extension from 2030 onward.

@sundogplanets Woot! Congratulations! And so cool that you had students helping to write it!

@oldclumsy_nowmad They're 2 different TNOs, showing 2 different resonant behaviours that we saw - the top one isn't in the resonance for 100% of the simulation

Your job sounds so much more fun than my job ever was.
AND I didn't have goats, either.

Thanks! That clarifies it for me.
