Astrophysical plasmas have the remarkable ability to preserve magnetic topology, which
inevitably gives rise to the accumulation of magnetic energy within stressed regions …

Magnetic storms on stars manifest as remarkable, randomly occurring changes of the
luminosity over durations that are tiny in comparison to the normal evolution of stars. These …

The ultraviolet (UV) emission of stellar flares may have a pivotal role in the habitability of
rocky exoplanets around low-mass stars. Previous studies have used white-light …

We present the first analysis of JWST near-infrared spectroscopy of stellar flares from
TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6–2.8 μm …

A 20 s cadence Transiting Exoplanet Survey Satellite monitoring campaign of 226 low-mass
flare stars during Cycle 3 recorded 3792 stellar flares of≥ 10 32 erg. We explore the time …

We present a multiwavelength study of stellar flares on primarily G-type stars using
overlap** time domain surveys in the near-ultraviolet (NUV) and optical regimes. The …

The high-energy radiative output, from the X-ray to the ultraviolet, of exoplanet host stars
drives photochemical reactions and mass loss in the upper regions of planetary …

Coronal mass ejections (CMEs) are a prominent contributor to solar system space weather
and might have impacted the Sun's early angular momentum evolution. A signal diagnostic …

We present light curves and flares from a 7 day, multiwavelength observational campaign of
AU Mic, a young and active dM1e star with exoplanets and a debris disk. We report on 73 …

High angular resolution cosmic microwave background experiments provide a unique
opportunity to conduct a survey of time-variable sources at millimeter wavelengths, a …
