I've had a fun couple of weeks working on resurrecting this newsletter with @joaoalves.bsky.social & @lillykormann.bsky.social!
I built a brand new website from scratch with JS+SvelteKit, which can link with forms & the arXiv API to look up papers and build a monthly newsletter automatically 👀

From February onwards, we're returning with monthly round-ups of star and planet formation papers, interviews, and more!

Ever wondered how many bins to choose when making a histogram of data? The answer is that you shouldn't choose a number of bins yourself! ☄️ #astrocode

New paper led by Fabian Polnitzcky & with @sratzenboeck.bsky.social + @joaoalves.bsky.social: based on the ages of stars with infrared excess in Sco-Cen, it seems planet-forming disks last around twice as long as previous estimates suggest - giving twice as long for planets to form. 🔭☄️ #exoplanets

A new census of OB associations with Gaia!
In this study, we took advantage of my OB stars map to find new OB associations within 1 kpc. The goal was to create a useful reference catalogue for this era, and to trace the star formation and structure of the local Milky Way.

The selection function of the Gaia DR3 open cluster census
Open clusters are among the most useful and widespread tracers of Galactic structure. The completeness of the Galactic open cluster census, however, remains poorly understood. For the first time ever,...

If we sweep the "unpleasant parts" of science history under the rug, then we're also doing a disservice to the many women who have lost chances at science careers because of past abuse, and we're neglecting a chance to learn something as a society about fixing it in the future.

Connecting different scales of SF and molecular cloud structure poses still many open questions. I propose the HPM (Hierarchical Pasta Model), connecting molecular gas at galactic scales to the smallest scales. Bigger baseline, 37 min of observation time + a redbull are needed. Fig: adapt. Hacar23

exam answer for why we should reject the filament idea: justice for spherical cows
yknow cows used to be spherical. nowadays they are elongated, filamentary. And sometimes they don't even collapse anymore. true astrophysics is dead.
