Thank you! Those LCs will be very useful I think.

One more question: the paper mentions you're providing the LCs detrended with unpopular as a HLSP on MAST - are those already available ?

Thank you for the info! I was just slightly surprised that these uncertainties don't depend at all on the amplitude of the signal, but then I thought maybe once the signal is detected, it's detected, and a larger amplitude doesn't necessarily lead to a smaller period uncertainty...?

This is a really impressive piece of work. I have a question about the period uncertainties. Did I understand correctly that these are obtained using the empirical methodology in Boyle et al. (2025b)? And that this means period uncertainty follows simple linear dependency on the Prot itself?

Here's a fun piece of code I wrote to visualize the astrometric orbital elements. To run the visualization for yourself, check it out here: github.com/sblunt/show-...

Black dashed is the line of nodes, and lighter purple indicates the part of the orbit that is behind the plane of the sky. Enjoy!

Thank you so much for the tip, Giorgia! I did manage to get what I needed via Vizier yesterday, but it's useful to have the options for the future!

It was an absolute pleasure hosting you, @johannavos.bsky.social, and hearing about the exciting work going on in your group. What fantastic datasets. I'm looking forward to learning lots more about the variability of ~Jupiter-sized objects in the coming months/years!

We are currently working with a Masters student, Jerry Cao, to test whether expanding the range of durations searched helps find more real transits and whether that's outweighed by an increase in the rate of spurious detection or not. Jerry is great and applying for astro phds right now BTW...

Is the lack of detections (black points) outside the red box real, or a selection effect? We won't know until we search for them

The green shaded area in figure shows the range of durations where transits could exist, when non-zero impact parameters and eccentricities are accounted for. The red line encloses the usual range searched.

We tried to post it on arXiv, but they declined - even after we appealed, apparently because it was "not of plausible interest for inclusion within arXiv". We are baffled and hugely disappointed by this decision, which makes absolutely no sense to us.

Interested in finding transiting planets at long periods, e.g. with the @platomissioncon.bsky.social?

We just published a Research Note led by Geert Jan Talens, showing that such transits can be much longer or shorter than usually assumed iopscience.iop.org/article/10.3...
