Paper day! Noah Tuchow has been working on how to calculate not just a planet's location in the Habitable Zone, but the *evolution* of its location within the Zone as its host star evolves. In our @AAS_ResNotes, he provides code to do this calculation: iopscience.iop.org/article/10.384…
Just concluded an incredible visit to @penn_state. To anyone thinking of applying to grad school there in @GeoscPSU, @AstroPSU, or @psumeteo, do it! They have incredible programs and diverse faculty that encompass the future of planetary science, exoplanets, and astrobiology.
Excited to be hosting @ExoCytherean here at Penn State on the day of this big new Nature Astronomy paper!
Astronomers: Please help us boost this ad! We are casting a wide net here and want a broad pool of applicants. We welcome applicants that would help us cross silos and are open to joint appointments across departments and colleges. Send any questions to Jason Wright.

New Faculty Job in Astronomy: Assistant Professor at Penn State. Come work in one of the largest and broadest departments in the country! We are a growing, vibrant, and collegial department in a town with a high standard of living. jobregister.aas.org/ad/7faa4f24
From the poster session: Evan Sneed (UC Riverside grad student) presents photochemical models of Archean-like exoplanet atmospheres. #Sagan2023
Congratulations to Dr. Macy Huston on their successful thesis defense! They will be joining UB Berkeley Astronomy as a postdoc in Jessica Lu’s group in the fall.
Congratulations to **Doctor** @ArvindFGupta !! @NEID_at_WIYN @AstroPSU
New paper led by @ArvindFGupta now on arxiv! We use a Fisher information approach to predict success of Earth-finding EPRV surveys and determine the preferred observing strats for different stellar noise sources. Lots of interesting results! (cc #EPRV5 😄) arxiv.org/abs/2303.14571
Astrobiologists take note: applications to attend the Oxygen in Planetary Biospheres workshop are now open! Space is very limited, and all invitees will have full travel expenses covered. greenbankobservatory.org/astrobio2023/ Deadline is Feb. 1.

Astrobiologists, save the date! May 5-7, 2023 at @GreenBankObserv, the 2nd Blumberg Memorial Workshop on Astrobiology: Oxygen in Planetary Biospheres Leaning towards junior researchers with international representation. See more here: greenbankobservatory.org/science/meetin… @astromeetings
Really excited to finally share some cool results I've been working on! In this paper (arxiv.org/abs/2210.00544), we use @NEID_at_WIYN and @NASA_TESS data to look at how p-mode oscillations manifest as a source of correlated noise for precision RV measurements. Some highlights:
It was fun to help on this project! I love that the first night of NEID science observations were used for some cool stellar astrophysics with EPRV implications; there’s something really cool about seeing p-mode oscillations resolved in the time domain. Check out Arvind’s paper!

Gave a talk at Penn State today and had soooo much fun. This place has so many friendly people doing interesting work, and everyone's giving me such insightful feedback! It's like all the best parts of AAS meetings!
Come join us studying planets at Penn State!
If you are at #aas240 and are or mentor a graduate student aiming to apply for fellowships next year, please find and talk with @Astro_Wright about CEHW and Penn State! We have a prize fellowship for astronomy, and can host 51 Peg b fellowships.
Are you at #aas240? Stop by the NOIRLab booth during the afternoon poster session (5:30 Wednesday) where @Astro_Wright will be on hand to answer all your questions about NEID!
