Celebrated the dead today on the día de Muertos at the department. Amazing how many similarities there are between Indian and Mexican traditions.

Interesting #astromethods paper came out recently that looks at whether or not large language models can replicate astrophysics papers.

They had a ~20% replication score, even with quite a lot of help. And this was just replicating papers - not doing anything new...

Today's reading begins with Lise Meitner, who co-discovered nuclear fission (she wrote the paper!) and was in general an INCREDIBLE trailblazing scientist.
Except, as a Jew, she had to flee Nazi Germany to Sweden and lost her professorship in Berlin. The men she worked with got the prize instead 🧪🔭

Just finished a complete night of observation. Dusk to dawn! Two more nights to go, all I am praying for now is some sleep.

Paper day!
You're doing ground-based high-resolution exoplanet transmission spectroscopy and want to analyse the planet—not the star or Earth's atmosphere.
Is there a way to disentangle your spectrum *without* destroying the planet signal?

Okay, now that I can stop talking with all caps, why is this important?
So, we're looking for planets like Earth, right? It's the only place we've found with life so far.
What makes it "Earth"? Well, some things include being a rocky planet, and being the right temperature for liquid water. (1/N)

After nearly a decade of saying which JWST result I was most excited about, it's here:
JWST SPECTRA OF THE HABITABLE TRAPPIST-1 PLANETS!
TRAPPIST-1 E!!!
IT'S ... A FLAT LINE!
BUT NOT AS FLAT AS IT COULD BE!?
IS THERE AN ATMOSPHERE?!?!?
WE STILL DON'T KNOWWWWW.

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!

Thus, discs may inherit these complex molecules from interstellar clouds.
