GPU-accelerated, direct N-body simulations of embryo growth starting from r ~ 100 km planetesimals provide realistic initial conditions for terrestrial accretion models that explore the birth of the solar system’s inner planets.

Daniel Stern and Dominic J. Walton 2020 ApJL 895 L38

Archival Keck data are used to identify for the first time, from a detected emission line, the spectroscopic redshift for the source gravitationally lensed into the first Einstein ring ever detected: MG 1131+0456.

Ivan N. Sharykin and Alexander G. Kosovichev 2020 ApJ 895 76

Analysis of helioseismic events — sunquakes — in Solar Cycle 24 shows that many strong sunquakes were produced by solar flares of low M class, and the sunquake mechanism is associated with high-energy particles.

Morpheus is a publicly available code that leverages advances in deep learning to perform source detection, source segmentation, and morphological classification of astronomical sources on a pixel-by-pixel basis.

Angelo Ricarte et al 2020 ApJL 895 L8

Simulations suggest that prior to quenching star formation, ram pressure on in-falling galaxies in a cluster triggers enhanced accretion onto the galaxy’s central black hole. AGN feedback then contributes to quenching.

A set of homogeneously derived properties of 186,301 Kepler stars is presented, allowing unprecedented investigations into trends in stellar and exoplanet properties as a function of stellar mass and age.
