Arvind Gupta

If anyone is interested in applying for this and wants to chat with a current fellow, please reach out! I'd be happy to talk about my experience in Tucson.

@budc1958 We do touch on the origin in the latter half of the article, plus a good deal of detail in the Methods. While we can't be certain, we think the planet may have started out similar to our own Jupiter before being forced onto its current orbit by the host star's binary companion.

@ArvindFGupta 2) I did give the article just a quick scan, but I didn't see anything about the presumed origin of the planet. Given the eccentric retrograde orbit, is it probable that it was captured from another star in a close encounter?

Pausing my twitter hiatus to announce my new paper published in Nature today: nature.com/articles/s4158… We confirm and characterize TIC 241249530 b, a warm Jupiter on an eccentric & retrograde orbit, and we show that it is en route to becoming a hot Jupiter ⤵️

@taylorjhoyt Thanks Taylor!

@ArvindFGupta Pausing my own hiatus to like and respond to this tweet...! Congratulations!

Astronomers using the @WIYNObservatory 3.5-meter Telescope at @NSF @KittPeakNatObs have discovered the extremely strange orbit of a rare exoplanet which holds clues to the formation history of hot Jupiters ow.ly/XWJQ50SEeNl 🖼️: NOIRLab/NSF/AURA/J. da Silva (Spaceengine)

@bsgaudi Unfortunately, no secondary eclipse -- secondary impact parameter is ~ 2.5. But the orientation of the orbit is sort of mirrored rel. to HD 80606. The transit occurs just a few hours after peri here, so JWST would be fantastic for a phase curve + transmission spec

@ArvindFGupta EXCELLENT! Congrats! Q: Is there a secondary eclipse? If so, what are the prospects for measuring the change in the thermal emission of the planet during periastron using JWST?

@ExoCytherean Thank you!

@ArvindFGupta Wow, amazing discovery Arvind! Congratulations!!

And here's a great thread from Jason with some historical context to add to just how cool this discovery is: x.com/Astro_Wright/s…

Thank you so much to everyone that helped - @jiayin_dong, @Astro_Wright, @SuvrathM, @shubhamkanodia, @markgiovinazzi, @cabridelle, @XianyuWang3, @gummiks, and lots more!

If any Tucson folks need a reason to show up, my puppy will be there and he will be requesting pets

I’ll be giving my thesis talk at #AAS243 Wednesday at 10 am in the Extrasolar Planets: Populations and Radial Velocities session. If you’re interested in the intersection of exoplanet searches 🪐 and stellar/solar ☀️astrophysics, come through! (And I’m on the job market 👀)

Officially #PhinisheD with grad school! I'll really miss the astronomy community at Penn State, but I'm so excited to be heading to Tucson as a @NOIRLabAstro Fellow in August!

@davidwhogg @meg_bedell I definitely plan to arrange something!

@ArvindFGupta @meg_bedell Please come back; it has been a pleasure.

The other paper (w/ Megan Bedell) is an in-depth exploration of EPRV exoplanet survey strategies from an information theory perspective, focusing on how we account for correlated noise arxiv.org/abs/2303.14571

Submitted my dissertation last week 🥳, which means I finally have time to talk about a couple of my papers that came out a little over a month ago. Threads below!
