When a bright star saturates the detector on JWST’s Mid-Infrared Instrument, the flux deficit that follows could produce false-positive exoplanet signals and degrade point-spread function subtraction.
The addition of a neural network to a foundational model used in solar wind forecasting enhances the flexibility of the model, allowing it to adapt to varying solar wind conditions.
Observations from multiple spacecraft stationed around our solar system revealed the longitudinal behavior of galactic cosmic ray flux decreases associated with a passing coronal mass ejection.
Microwave observations by the Juno spacecraft and modeling of impact-induced dirtiness place strong constraints on the degree of contamination of Ganymede’s surface as well as the total impact flux.
New modeling provides insight into the coronae of solar-type stars that rotate far more rapidly than the Sun, yielding X-ray spectra and luminosities for these dense and ultra-hot coronae.
An analysis of the solar energetic particle proton population suggests that the temperature of this population hovers around 1 MeV while the density spans several orders of magnitude.
