Proxy-based Prediction of Solar Extreme Ultraviolet Emission Using Deep Learning [PDF]
The Astrophysical Journal Letters, 2021 Abstract High-energy radiation from the Sun governs the behavior of Earth’s upper atmosphere and such radiation from any planet-hosting star can drive the long-term evolution of a planetary atmosphere. However, much of this radiation is unobservable because of absorption by Earth’s atmosphere and the interstellar medium.

Radiation Pressure Acting on the Neutral He Atoms in the Heliosphere
The Astrophysical Journal, 2023 Interstellar neutral helium (ISN He) is an important source of information on the physical state of the local interstellar medium. Radiation pressure acting on the neutral helium atoms in the heliosphere has always been neglected; its effect has been ...

The Astrophysical Journal, 2022 Abstract The hydrogen Lyα (H i Lyα) emission during solar flares has rarely been studied in spatially resolved images, and its physical origin has not been fully understood. In this paper, we present novel Lyα images for a C1.4 solar flare (SOL2021-08-20T22:00) from the Extreme Ultraviolet Imager aboard Solar Orbiter, together with multi-

Explosive events in the solar atmosphere seen in extreme-ultraviolet emission lines [PDF]
Astronomy & Astrophysics, 2005 We present observations of explosive events (EEs) in the solar atmosphere obtained with the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) spectrometer on the Solar and Heliospheric Observatory (SOHO) in the wavelength range from about 750 A to 790 A.

A Model for Gradual-phase Heating Driven by MHD Turbulence in Solar Flares
The Astrophysical Journal, 2023 Coronal flare emission is commonly observed to decay on timescales longer than those predicted by impulsively driven, one-dimensional flare loop models.

Statistical analysis for EUV dynamic spectra and their impact on the ionosphere during solar flares
Earth, Planets and Space, 2023 The X-rays and extreme ultraviolet (EUV) emitted during solar flares can rapidly change the physical composition of Earth’s ionosphere, causing space weather phenomena.

The Astrophysical Journal, 2022 The propagation direction and true velocity of a solar coronal mass ejection, which are among the most decisive factors for its geo-effectiveness, are difficult to determine through single-perspective imaging observations. Here we show that Sun-as-a-star
