How hard is it to do science in a language that’s not your first language? We quantified the severity of #languagebarriers for non-native English speakers when reading/publishing papers and attending/presenting at international conferences. doi.org/10.1371/journa… 1/9

Paper day! SPHERE images of seven eruptive stars and their spectacular surroundings: turns out the streamer in Z CMa is part of a huge outflow, EXors have relatively faint disk-like structures except for XZ Tau, and more in 👇 arxiv.org/abs/2403.12124 #MilenioYEMS Astrofísica CIRAS

New paper! In work led by Rebecca Martin, we study in the context of Be/X-ray binaries an old question: when does gas escape the system through the L2 point? We find that the disk aspect ratio largely controls tidal truncation and mass escape. arxiv.org/abs/2404.17976

For the first time in their history, Argentina are #HSBCSVNS League winners! 🇦🇷🏆 Los Pumas 7s

I am thrilled to share that after 5 amazing years at University of Arizona I will join Universidad de Concepcion Astronomía UdeC as an assistant professor. It's been a great journey at Steward Observatory, University of Arizona and can't wait for the new adventures to come at Universidad de Concepción and the grand southern Chile.

Leaving the US after 5 years. We surely had a great time! Meet amazing friends. Not easy to say goodbye but here we go all packed!

I would like to advertise our recently accepted paper led by David Velasco-Romero at Princeton University. #FARGO3D simulations show that eccentric planets (0.1-8 Earths) can get locked near dust rings due to their own accretion (heating/thermal torque). Link: arxiv.org/pdf/2407.16546

Encantado de presentar junto a Leonardo Krapp nuestro trabajo sobre #FARGO3D en #CARLA2024. Luego de 10 años, aún nos encontramos a la vanguardia en el uso de #GPUs en simulaciones astrofísicas. Agradezco a los organizadores y a quienes han contribuido al desarrollo de FARGO3D.

Preprint of my review chapter on planet-disk interactions for the upcoming Encyclopedia of Astrophysics is on arXiv. It provides a first solid approach into planet-disk interactions for both undergraduate students and researchers from other fields. arxiv.org/abs/2410.00374

A great review article by Pablo Benitez Llambay on planet-disk interaction. The article covers many aspects of planet migration with a thorough and yet simple description. Excellent text for both uninitiated and advanced students. Highly recommended arxiv.org/abs/2410.00374

New work, led by Wenrui Xu with the planet formation group @FlatironCCA, on gravitational instability in protoplanetary disks. Wenrui's work breaks new ground by using "full transport" radiation hydro to follow the physics with unprecedented realism. arxiv.org/abs/2410.12042

New paper! In work led by Sabina Sagynbayeva @SabinaAstro and the planet formation group @FlatironCCA, we show that "classical" circumplanetary disk formation is hard at large orbital radii. This may be (in part) why to date observed CPDs are rare. (1/7) arxiv.org/abs/2410.14896

In this experiment with my new code nebula I simulate the ethereal beauty of light penetrating dense clouds. By leveraging the power of GPUs, we can explore the intricate interplay between light and volumetric media, creating visually stunning and immersive experiences.

When our new tech for sphviewer2 intersects with the genius of Pablo Benitez Llambay and his new nebula code, you get stunning images like this: an SPH dusty galaxy. I don’t recall seeing anything this cool! Stay tuned for more exciting developments in simulation rendering tools!

Ever wondered what a circumplanetary disk would look like up close? With #nebula and high-resolution dusty #FARGO3D simulations made by Leonardo Krapp we're starting to get a glimpse. And yes... There is a planet embedded in that dusty cloud! 🪐

Jiayin Dong Jiayin Dong, Dan Tamayo Daniel Tamayo and I will host a workshop April 22-25 Flatiron CCA in New York on methods and applications of ML for planetary dynamics and exoplanet population inference. Express your interest in attending by 3/3/25: forms.gle/k2WVVDPGLuuyyq…

We’re hosting a workshop on Machine Learning in Planetary System Dynamics Flatiron CCA April 22-25, covering a range of topics at the intersection of dynamics, exoplanet populations, planet formation, and ML. Link to apply in replies: we’ll start sending invites next week!

Our new paper with Ximena Ramos on a comoving framework for planet migration is on arXiv! Simulating planets moving through their disk is computationally expensive. Our new method solves this by keeping the planet fixed, making simulations over >10x faster!

Thomas Pfeil and I are organizing a workshop on Hydrodynamic and Dusty Turbulence in Protoplanetary Disks Flatiron Institute in New York, Feb 23-35 (2026). Details, and a short form to express interest in attending, at the link below: users.flatironinstitute.org/~parmitage/Dis…
