AI Poincaré: Machine Learning Conservation Laws from Trajectories

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Max Tegmark, , , | Summary: We present AI Poincar’e, a machine learning algorithm for auto-discovering conserved quantities using trajectory data from unknown dynamical systems. We test it on five Hamiltonian systems, including the gravitational 3-body problem, and find that it discovers not only all […]

Collapsar R-Process Yields Can Reproduce [Eu/Fe] Abundance Scatter in Metal-Poor Stars

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Alexander P. Ji, Maria R. Drout, Anna Frebel, | Summary: It is unclear if neutron star mergers can explain the observed r-process abundances of metal-poor stars. Collapsars, defined here as rotating massive stars whose collapse results in a rapidly accreting disk around a black hole […]

Tuning Advanced LIGO to kilohertz signals from neutron-star collisions

Kavli Affiliate: Lee McCuller | First 5 Authors: Dhruva Ganapathy, Lee McCuller, Jameson Graef Rollins, Evan D. Hall, Lisa Barsotti | Summary: Gravitational waves produced at kilohertz frequencies in the aftermath of a neutron star collision can shed light on the behavior of matter at extreme temperatures and densities that are inaccessible to laboratory experiments. […]

The Occurrence of Rocky Habitable Zone Planets Around Solar-Like Stars from Kepler Data

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu, Jeffrey L. Coughlin, William J. Borucki | Summary: We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties. We provide the […]

Phase Curves of Hot Neptune LTT 9779b Suggest a High-Metallicity Atmosphere

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan, Tansu Daylan, Ian Wong | Summary: Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements made to date are of […]
