hi new followers 👋

quick intro - I'm Adina, currently a NASA Sagan fellow at Michigan State, but I'll be starting as an assistant prof here next year 👩🏻‍🏫

my research focuses on observing very young planets and stars 🌟🪐🔭

I'm a crafter 🧶, baker 🥧, cat-mom 🐱, and Halloween enthusiast 🎃👻

⭐️paper day!⭐️

hey now, we found thousands of stellar variability periods, including ~26k very high likelihood new ASAS-SN rotation periods from cool dwarfs!

(also I have missed abt 5 typos in this version already, but it’s only been submitted to ApJS so it’ll get fixed!)..

200,000+ Deep Learning Inferred Periods of Stellar Variability from The All-Sky Automated Survey for Supernovae

Stars exhibit a range of variability periods that depend on their mass, age, and evolutionary stage. For space-based photometric data, convolutional neural networks (CNNs) have demonstrated success in...

The 16-year-old who shot two students in a Colorado high school on the same day Charlie Kirk was killed was a virulent white supremacist and antisemite www.denverpost.com/2025/09/11/e...

‘Radicalized’ Evergreen High School shooter appeared to hold antisemitic, violent views in online accounts

Social media accounts that appear to be connected to the 16-year-old shooter are littered with references to mass shootings and antisemitic views, The Denver Post found.

The attack on Charlie Kirk is horrifying.

Political violence has no place in this country and should never become the norm.

I’m sending my sympathies to his family and friends at this time.

petition to talk about tenure contracts the same way NFL players talk about their contracts.

For example, an assistant professor would have a 75 percent six-year contract with a possible extension and a signing bonus (start-up)

Today our team released findings on the nature of the interstellar object 3I/ATLAS, based on our first round of JWST observations. The data are incredible: Not only did we detect and map gas and dust in the coma, but we found that 3I is one of the most CO2 rich comets ever seen! Check it out:

JWST detection of a carbon dioxide dominated gas coma surrounding interstellar object 3I/ATLAS

3I/ATLAS is the third confirmed interstellar object to visit our Solar System, and only the second to display a clear coma. Infrared spectroscopy with the James Webb Space Telescope (JWST) provides th...

Apparently zero TESS proposals were "selected" because they don't know about funding. Best ranking you can get is "selectable". 🧪🔭 #exoplanets

Massive protests have broken out in Israel calling for Neyanyahu to step down, a deal to return the hostages, and to end the Gaza genocide.

300,000 protested in Tel Aviv, 2.5 million gathered around the country. #3E #FreePalestine

A chart of level, color, significance category, and key observable criteria. this ranking is supposed to provide a way to categorize interstellar objects from completely natural phenomena to aliens about to attack us. this was created by a team of scientists who are spreading misinformation about interstellar objects.

We were able to get the application portal closed for the astronomy graduate program at @michiganstateu.bsky.social for the upcoming cycle. Not an ideal circumstance, but we wanted to communicate this to the community as early as possible.

Sign of the times- Michigan State, one of the biggest astronomy programs in the USA, is not accepting ANY applications for its graduate program this year 😖

💀Adina Feinstein PhD 💀 @afeinstein20.bsky.social · Jul 30

this is due to a combination of (a) having a wayyy bigger than expected incoming class and (b) the state of federal funding

as much as it sucks, it's important to be transparent about where we stand. hopefully other departments will follow

I've had a few other former astronomers reach out to me lately about transitioning into data science/ML, and I decided to write about it.

This is my personal journey from astro to ocean, and the most useful steps I took along the way.
