hi new followers ๐
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 ๐ฉ๐ปโ๐ซ
my research focuses on observing very young planets and stars ๐๐ช๐ญ
I'm a crafter ๐งถ, baker ๐ฅง, cat-mom ๐ฑ, and Halloween enthusiast ๐๐ป

if you're tired of ai crap, I highly recommend going to see LAIKA's Wildwood. it's refreshingly human handmade stop motion animation is stunning and it's the best movie I've seen in a very long time
โWeโve established that the observatory is fully functional,โ said Julie McEnery, #NASARoman senior project scientist at NASAโs Goddard Space Flight Center. โThe telescope can guide and take exposures, data flows appropriately, and we can slew from one place to another for observations.โ ๐ญ
I would like to see a new feature on arXiv that labels preprints that use AI upfront, since apparently TWO slop papers were successfully uploaded to the preprint server over the last two nights...

interestingggg.... paper on the arXiv tonight of a new planet candidate found with and written up entirely by AI, including the caveat, "The author has not independently checked the analyses and does not have the expertise to verify every technical detail."

Likely the most important thing I've ever written โ if you're an academic and the AI mania unsettles you, here's my best shot at presenting some intellectual tools that might help you articulate why.

I haven't gone through the details of the manuscript myself. While supervised ML/AI in planet detection/confirmation (as has been done before) is incredibly powerful, I feel this crosses a line
Important for #astrosky: Overleaf seems to upgraded to TeXLive v2026 in the past few days, and as a result, your aastex v7 / aasjournal v7.1 might be broken.

We're back with Part II - A detailed analysis of the starspots on the young solar analog V1298 Tau as viewed with JWST @jwstobserver.bsky.social and LCO led by MSU postdoc Matthew Murphy ๐ #stellarastro

and the big takeaways below!
This is all cool because planets are cool, but what about the spots?
Well... Stay tuned for a follow-up paper in the next few weeks where we fully characterize the spots on this young solar analog to see how they differ from the Sun ๐๐
we combine the JWST observations with contemporaneous g' and r' band observations from the Las Cumbres Observatory, giving us a global view of V1298 Tau
by fixing the spots along the transit chords and fitting the light curve, we achieve a global view of the spots on this young solar analog!
for the first time, we find the temperature and the umbral-to-penumbral area ratio of the spots on V1298 Tau are consistent with solar, although the number of spots is VERY different!
our work highlights how exoplanet transits can probe stellar photospheric properties ๐ similar to Murray+2026!

We observed transits of V1298 Tau cdb and found... a lot of spots. like so many spots. Using fleck, we find the transits are best-fit by ~6 spots per transit chord
by measuring the change in spot amplitude as a function of wavelength, we measure the umbral and penumbral temperatures of the spots!

We detected water in the atmosphere of the planet!
From our retrieved water abundance, we find that V1298 Tau c has a low-metallicity atmosphere! This is consistent with other young planets and suggests that planets likely evolve to have metal-enriched atmospheres ๐

We observed a single JWST NIRISS/SOSS transit of V1298 Tau c. During its transit, we identified SIX (!) starspot crossing events!!
We tried to fit the transit using different frameworks to account for the spot crossings (masked, gaussians, fleck, or gp). Regardless of how the spots were fit...
#nsf canceled #geoscience postdocs. Thatโs nifty. Letโs pretend we arenโt messing up the planet and be super sure to stop training people who can help. eos.org/research-and...
Michigan State's Darryl Seligman discusses how interstellar interlopers and dark comets are challenging our understanding of the behavior and properties of comets and asteroids.
Today's lecture is part of the weekly 2026 Spring Colloquium talks at STScI.
Welcome to the new fellows selected to pursue their research in space science at ESA!
Their projects span a broad range of topics from investigating the nature of dark matter to learning how Jupiterโs atmosphere works.

astro hive mind - a student in my intro to astro for non-majors class asked about good astronomy documentaries they could watch. does anybody have any recommendations? ๐ญ ๐#astronomy

we were talking about solar flares and solar activity cycles in the intro astro for non-majors class today and somebody asked, "Do solar flares happen more frequently if a star spins faster?"
ngl, I was shook by this intuition ๐ช
