When I get anxious these days, I open @arXiv and start scrolling through papers as if the solution to my stress is buried in a preprint. Some people eat their feelings - I read mine :-) Stress reading, anyone?

Draft of our recently submitted paper is on ArXiv! Led by Octavio Guilera, we investigate the impact of dust torque on the migration of planetary cores including disk evolution, dust growth, and planet migration. arxiv.org/abs/2501.16169 🧵

We just launched Corca—a collaborative math editor. The main idea: there’s no 'text editor' for math. If you want to work on equations on a computer, there’s no app designed for that—so the only real option is paper. ↓

The chance of asteroid 2024 YR4 hitting out planet in 2032 is now 1.5%, or 1 in 67. The OVERWHELMING likelihood is that the asteroid will miss Earth. But for the first time ever, we might have to seriously consider a deflection mission soon. Let me explain. 🧵 (1/x)

The real issue is treating natural and social sciences as separate intellectual silos. And the STEM superiority complex that mistakes methodological rigor for inherent intellectual worth.

God I miss overcast skies and rain 😭

Our new paper, in collaboration with Richard Richard Alexander , is out today 🥳! We propose a new mechanism for forming radially compact protoplanetary discs, which are common in ALMA star-forming region surveys. 🧵1/n arxiv.org/abs/2502.04452

2D multi-fluid Athena++ simulations of the water snow line, led by Yu Wang, provide the best (theoretical) evidence yet that planetesimal formation may be strongly enhanced there. Great to have Yu here Flatiron CCA this Spring as a predoc! arxiv.org/abs/2502.08936

When you reappear in people's lives after inexplicably disappearing for several months.

Wangari Maathai was the first African woman to receive the Nobel Peace Prize. She started the Green Belt Movement to counter deforestation and mobilise African women to think sustainably. “Throughout Africa, women are the primary caretakers, holding significant responsibility

Very interesting paper led by Marion Villenave: a uniform analysis of dust settling in protoplanetary disks and what it implies for turbulence, pebble accretion, and the vertical shear instability. Nice to see this done! arxiv.org/pdf/2503.05872

It's that time of the year again. Sigh.

My entire school education from KG to grade 12 cost me less than this.

Dunno why but this works.

This is what the ideal date looks like

📡ALMA Inspires New Models for the Evolution of Planet-Forming Disks. By combining ALMA observations and simulations, the ODISEA team traces how planets may form and reshape their disks 🔗almaobservatory.org/en/press-relea…

Giant planets on wide, eccentric orbits (like the putative Planet 9) may form when stars are embedded in their natal stellar clusters. Sims suggest a 1-5% chance of such planets forming in exoplanetary systems and up to 40% in the Solar System. bit.ly/3ZDBkSq

New paper! In work led by Alessandro Ruzza (Milan), we develop a simulation-based inference (SBI) pipeline to determine the masses of planets inferred from dust continuum observations of protoplanetary disks, and apply it to ~50 observations of gaps. Thread (1/6)

To bloom, phytoplankton must cross stratified shear layers. Simulations show that different types of instability affect scalar fluxes and mixing, accelerating phytoplankton growth, especially when physical and biological timescales match. Read more at go.aps.org/4mV35iW
