BREAKING: WE WON!!! 💥 💥 💥 Federal Judge William G. Young ruled today in our lawsuit against the Trump administration that the policy of arresting, detaining, & deporting noncitizen students & faculty members for their pro-Palestinian advocacy violates the 1st Amendment. Full ruling here:

Super excited about my new paper coming soon with Isabel Colman and @farrwill.bsky.social !! This project quickly became another statistics bootcamp for me. 😅

Hooray for amazing collaborators!!!

I learned a new word this weekend: Congratudolences! It’s what you say when someone wins a something that is arguably an honor… but will also lead to more work. Like the winner of the pie eating contest & the prize is more pie. Or being elected department chair. Hi! I’m the new CUNY Astro chair!

You know about Pavlov's bell. Pavlov grabbed some dogs, rang a bell before feeding them, and eventually the dogs started to salivate when the bell rang, regardless of whether they were given food or not. Now, let's say you studied the brain activity of those dogs. 🧵

Some tidbits about the most recent 1,000 exoplanets: - Nearly half (~490) were discovered with NASA's TESS mission - As a result, their host stars are nearly *10 times brighter on average* than previous stars! - We have found a lot more cool giant planets (Jupiter analogs), with RV and imaging

I have a fun new paper out that demonstrates the power of combining radial velocities (RVs), astrometry, and dynamical simulations in understanding planetary system demographics. You can access the paper here: arxiv.org/abs/2509.12334

One thing I am proud of in my PhD is creating collaborations with the nicest people. All my research meetings are just full of positive vibes*❤️. (You guys were kind of bad at saying no to me and I’m so glad you were 😂) *sometimes I complain about characters in TV shows but I assume people enjoy it😅

My paper with Loucas Pillaud-Vivien and Lawrence Saul, “Variational Inference for Uncertainty Quantification: An Analysis of Trade-offs”, has been accepted for publication in the Journal of Machine Learning Research. 📃 arxiv.org/abs/2403.13748 🧵 1/

The real statistics I’d like to see is how many times I used “therefore” in this job season. 😅

STScI's Dr. Néstor Espinoza will explore some of the most exciting findings #NASAWebb is unveiling about the atmospheres of distant exoplanets. 🔭 🧪 DATE: Wednesday, September 17, 7 p.m. ET: https://youtube.com/live/i466qvWBQ1o?feature=share

Super excited that these results are finally out! This is the highest resolution ALMA image of Fomalhaut ever, and we can learn new things about the structure of the disk and the planet that is likely shaping it. Press release here: public.nrao.edu/news/neighbo...

Immensely enjoying the headline of this NASA press release from 15 years ago. www.nasa.gov/news-release...

Update on the atmosphere vs no atmosphere debate for TRAPPIST-1 b and c -- here's a nice and (IMO) conclusive result from Gillon and Ducrot et al.: no thick atmosphere on either planet. arxiv.org/pdf/2509.02128

The imperial boomerang in today’s form is that the more we tolerate the murder of people in Palestine with drones, the closer we all come to being murdered by drones anywhere in the world

Reminding you that I am looking for postdocs this Fall 👀

Sweet NASA feature article on @sabinastro.bsky.social's work on mapping stellar surfaces: 🔭🧪 #stellarastro science.nasa.gov/missions/tes... Why? Because: 1) #StarsAreStillInteresting 2) Messy stars complicate our view of exoplanet atmospheres. To remove stellar contamination, you must map it. 🗺️

My first press coverage 🥹 protect.checkpoint.com/v2/r01/___ht...

Lowkey don’t want this to be confirmed cause don’t want to say the name of this star in talks (or type it out in papers)

@caltechipac.bsky.social is featuring me in their "Meet the Scientists" profiles! Check it out to learn more about how I became an astronomer, what I work on, and how I ended up at IPAC! www.ipac.caltech.edu/meet-the-sta... #exoplanets 🔭🧪

Kepler mission: smaller stars have more short-period, small #exoplanets. Theory: the smallest stars won’t have enough disk material to make small planets so there must be a turnover. Kepler+K2: We have found a turnover! Check out our newest Scaling K2 paper: arxiv.org/abs/2508.05734 🧵 1/9 🔭🧪☄️

Hey, astro peeps! I am on job market this Fall! Let me know if you have a postdoc position available! I am an expert (that’s a scary word, but I am) in exoplanets 🪐 and stars ⭐️!!! Doing lots of data analysis! Please, check out my website to know more about my work! ssagynbayeva.github.io

I am community sourcing a list of people who are actively in search of MS/PhD students in planetary science/astrobiology/exoplanets for Fall 2026. If you are such a person, please fill out the following google form: docs.google.com/forms/d/e/1F...

Requirements for Joint Orbital Characterization of Cold Giants and Habitable Worlds with Habitable Worlds Observatory. Sabina Sagynbayeva et. al. https://arxiv.org/abs/2507.21443

A timely paper for #HWO25: is it enough to find Earth-like planets around other nearby stars? No! We need their planetary system contexts. Does life on Earth depend on Jupiter? @sabinastro.bsky.social led this nice analysis of HWO requirements to detect Earths + Jupiters. arxiv.org/abs/2507.21443

A new bombshell has entered the arxiv villa!!! I.e., my new paper is on arxiv. Go read it!!! (A thread soon) arxiv.org/abs/2507.21443

Two-page proposals for a general audience is actually insane. 😭 Like you just have to believe whatever I say!

I received a very scary scam call saying they are going to arrest me cause I didn’t fill out some immigration form. They were very scary, they acted on my fear of prison and deportation, and they do this to many international students. I didn’t send anything, but have to warn all other students.

My Circumplanetary disks paper just got accepted for publication in ApJ! 🪐 Will do a thread on it soon!

OMG THE Phil Armitage is on bluesky!!!!

@sabinastro.bsky.social and @farrwill.bsky.social do what they do best: tackling a really hard problem with careful, creative, and thorough methods. 👏 🧪🔭 #stars #planets

Okay, here we go! A thread on my paper with my favorite people @farrwill.bsky.social , @brettmorr.is , and Rodrigo Luger (not sure he knows he’s on the paper😂). It’s submitted and on ArXiv right now! arxiv.org/abs/2504.21852
