Thank you to everyone who helped out on both of these papers. I am excited to continue to see where these projects take us and what else we can learn about how planets form and evolve 🔭

In SOYSAUCE 1, we analyze the RM of TIDYE-1b (aka IRAS 04125+2902 b) and introduce our new survey targeting young stellar obliquities and planet atmospheres, with hopes of better understanding when and how planets become misaligned from their host stars 💫

In TIDYE 4, we report the discovery of a baby #exoplanet, this time in Vela. TOI-6448 is a 34Myr sun analog hosting a 9ish Re planet. Another giant baby! 🧸

Check out the latest new planet from the Young Worlds Lab from @madysonbarber.bsky.social! TOI-2076e, a 200 Myr planet just a bit bigger than Earth (1.3Re). 🔭🧪🪐⭐ #exoplanet #exoplanets #tess #unc #uncresearch arxiv.org/abs/2505.06358

TESS Investigation -- Demographics of Young Exoplanets (TI-DYE) III: an inner super-Earth in TOI-2076
Young (<500 Myr) multi-planet transiting systems are valuable environments for understanding planet evolution by offering an opportunity to make direct comparisons between planets from the same format...

#carrboro and #chapelhill friends! Check out Physics from the Ground Up. Tomorrow (Dec 3) at 6pm at Lanza's Cafe. ☕🔭🧪🪐⚛️ Hear from Madyson Barber (@madysonbarber.bsky.social) on her the youngest transiting planet and Stephen Yates on lesser known physicists of the Middle Ages. See you there!
Physics from the Ground Up will be wrapping up the semester TOMORROW 12/3 with talks from graduate students Madyson Barber and Stephen Yates. 

As usual, we will be at Lanza's Cafe in Carrboro starting at 6pm.

I’m happy to share that the first draft version is now on arXiv. There are slight differences in the stellar and planetary parameters, but the result is the same: a giant baby planet and a misaligned disk! arxiv.org/abs/2411.18683

A giant planet transiting a 3-Myr protostar with a misaligned disk
Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack of such discoveries ...

hi Bluesky! I’m Madyson, a 3rd-year phd student at unc chapel hill discovering and studying young transiting planets. Maybe you saw our recent Nature paper on the discovery of my new favorite, IRAS 04125+2902 b (aka TIDYE-1b 😉) www.nature.com/articles/s41...
