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.

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.
Lorenzo Spina et al 2020 ApJ 895 52
High-resolution spectra of 211 Sun-like stars are used to analyze how magnetic fields and stellar spots can alter the equivalent widths of absorption lines in stellar spectra, varying during the star’s activity cycle.

New measurements of the chemical properties of haze particles produced in laboratory analogs of exoplanet atmospheres provide insight into chemical atmospheric processes and prebiotic chemistry on distant worlds.
