Positive Association Between Coastal Sea Surface Temperatures and Humid Heat Stress on Nearby Land

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Large populations along Earth's coastlines are exposed to climate hazards including extreme humid heat. Considering observed coastal ocean warming and increased coastal marine heatwave (MHW) activity, we seek to uncover if, how, and where coastal ocean temperatures are linked with heat and humidity on land nearby.

Simulated Coronal Mass Ejections on a Young Solar-type Star and the Associated Instantaneous Angular Momentum Loss

The Astrophysical Journal
Coronal mass ejections (CMEs) on stars can change the stars’ magnetic field configurations and mass-loss rates during the eruption and propagation and therefore, may affect the stars’ rotation properties on long timescales.

Stellar Coronal Mass Ejections with HWO: A Science Case Concept

The primary mission of the Habitable World Observatory (HWO) will be to constrain the prevalence of life on Earth-like planets. These planets will be subject to impacts by energetic particles generated from coronal mass ejection (CME) shocks that can dramatically deplete ozone, a key biosignature gas.

Interplanetary Type IV Solar Radio Bursts: A Comprehensive Catalog and Statistical Results

The Astrophysical Journal
Decameter hectometric (DH; 1–14 MHz) type IV radio bursts are produced by flare-accelerated electrons trapped in postflare loops or the moving magnetic structures associated with the coronal mass ejections (CMEs).

Doppler-shifted Signatures in the Chromospheric Line Profiles of II Pegasi

The Astrophysical Journal
Stellar flares are frequently accompanied by prominence eruptions, coronal mass ejections (CMEs), and other forms of plasma motion. Based on the long-term high-resolution spectroscopic monitoring data set of the RS CVn-type star II Pegasi (II Peg), we ...

Stellar Magnetic Storm Induced Magnetospheric Polarity Reversals: A Potential Diagnostic for Distinguishing Unmagnetized and Magnetized (Exo)planets

The Astrophysical Journal
(Exo)planetary environments are forced by stellar activity, which manifest through variable radiation, particle and magnetic fluxes, stellar winds, flares, and magnetic storms known as coronal mass ejections (CMEs). Recent studies have shown that planets

Validating DIRECD: Statistical Evaluation of Coronal Mass Ejection Direction Estimates from Coronal Dimmings

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are among the most energetic phenomena in our solar system, with significant implications for space weather. Understanding their early dynamics remains challenging due to observational limitations in the low corona.

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. I. Discovery of Prominence Eruptions Associated with Superflares

The Astrophysical Journal
Young solar-type stars frequently produce superflares, serving as a unique window into the young Sun-Earth environments. Large solar flares are closely linked to coronal mass ejections (CMEs) associated with filament/prominence eruptions, but ...

Where are the stellar coronal mass ejections?

Flares and coronal mass ejections (CMEs) can have serious effects on their surroundings: they can erode or completely destroy atmospheres of orbiting planets over time and also have high importance in stellar evolution.
