Predicting the long-term stability of compact multiplanet systems

Kavli Affiliate: David Spergel | First 5 Authors: Daniel Tamayo, Miles Cranmer, Samuel Hadden, Hanno Rein, Peter Battaglia | Summary: We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compact multi-planet systems over long timescales of $10^9$ orbits. Our Stability […]

Inferring the properties of a population of compact binaries in presence of selection effects

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Davide Gerosa, Will M. Farr, Stephen R. Taylor, | Summary: Shortly after a new class of objects is discovered, the attention shifts from the properties of the individual sources to the question of their origin: do all sources come from the same underlying population, or […]

ALMA Observations of Young Eruptive Stars: continuum disk sizes and molecular outflows

Kavli Affiliate: David A. Principe | First 5 Authors: Antonio S. Hales, Sebastián Pérez, Camilo Gonzalez-Ruilova, Lucas A. Cieza, Jonathan P. Williams | Summary: We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm observations of four young, eruptive star-disk systems at 0.4" resolution: two FUors (V582 Aur and V900 Mon), one EXor (UZ Tau E) […]

Revealing the formation mechanism of the shell galaxy NGC474 with MUSE

Kavli Affiliate: Eric Peng | First 5 Authors: Jeremy Fensch, Pierre-Alain Duc, Sungsoon Lim, Éric Emsellem, Michal Bílek | Summary: Stellar shells around galaxies could provide precious insights into their assembly history. However, their formation mechanism remains poorly empirically constrained, in particular the type of galaxy collisions at their origin. We present MUSE@VLT data of […]
