In the last three decades, knowledge of planetary systems other than our own has increased
rapidly with the discovery of over 5,000 exoplanets (Christiansen 2022). These worlds vary …

Stellar flares present challenges to the potential habitability of terrestrial planets orbiting M
dwarf stars through inducing changes in the atmospheric composition and irradiating the …

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 conducted the time-resolved simultaneous optical spectroscopic and photometric
observations of mid-M-dwarf flare stars YZ CMi, EV Lac, and AD Leo. Spectroscopic …

Determining the habitability and interpreting atmospheric spectra of exoplanets requires
understanding their atmospheric physics and chemistry. We use a 3-D coupled climate …

Using a 3D general circulation model, we demonstrate that a confirmed rocky exoplanet and
a primary observational target, TRAPPIST-1e presents an interesting case of climate …

Context. Stellar flares of active M dwarfs can affect the atmospheric composition of close-
orbiting gas giants, and can result in time-dependent transmission spectra. Aims. We aim to …

We present a detailed analysis of a superflare on the active M dwarf star AD Leonis. The
event presents a rare case of a stellar flare that was simultaneously observed in X-rays (with …
