I found a new planetary candidate in Kepler Data with AI

关于

Hey HN! I was playing around with the Kepler and TESS data last weekend when I hacked around a way to pixel-peep stars dimming periodically to potentially find new exoplanets with Codex. I ended up running the engine to find an interesting signal in Kepler data that was uncatalogued with a dip repeating every 13.77 days around KIC 5689121, a red dwarf in Lyra about 970 light-years away. If it's a planet, it'd be roughly 2.5–3 times Earth's radius ! Funnily enough, this candidate is just 7.1 arcseconds from a much brighter neighbour (KIC 5689116) and is very hard to see because of how much brighter it is (probably why it went unnoticed for so long) Of course, there's work to do before calling it confirmed - my TRICERATOPS analysis is about 6.9% and we have to get IR/AO / Keck observations to prove it's out there ! (which I'm honestly intimidated by but cautiously optimistic about because I've never worked in non-CS adjacent research) but I found the activity of making cool tools to potentially discover things about our universe quite fun ! Would love feedback, especially from anyone who's worked with Kepler data or exoplanet validation :) https://x.com/kuberwastaken/status/2109240782368751834
