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?

TSD: An inverse problem approach for recovering the exoplanetary atmosphere transmission spectrum from high-resolution spectroscopy

Our ability to observe, detect, and characterize exoplanetary atmospheres has grown by leaps and bounds over the last 20 years, aided largely by developments in astronomical instrumentation; improveme...

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!

ALMA found evidence for complex organic compounds, such as sugars & amino acids, in a protoplanetary disc.

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

The evolution of life may have its origins in outer space

Astronomers find complex organic molecules – precursors to sugars and amino acids – in a planet-forming disc.

I work on exoplanet demographics to better understand planet formation and evolution pathways among low mass stars, mainly for my doctoral thesis.
