228. White-Light and Lyα Emissions in Solar Flares: Timing, Timescale, Energy, and Scaling

Contributed by De-Chao Song. Posted on June 3, 2026

Using SDO/HMI white-light continuum observations and GOES Lyα and SXR irradiance, this study investigates 69 solar white-light flares to examine their emission properties, including enhancement, peak-time ordering, evolutionary timescales, and relationships between the emission parameters and radiated energy.

106. The vector magnetic field of the Sun-as-a-star during activity cycle 24

HMI-observed vector magnetic-field maps were lowered to a resolution of l_max=5, so that a comparison between solar and stellar magnetic field is possible.

77. Statistical Study of Solar White-light Flares and Comparison with Superflares on Solar-type Stars

Statistical studies find that white-light flares from the Sun and from solar-type stars have similar energy-duration relations, but the stellar flares have shorter duration. Cooling effect and stronger magnetic field in the stellar corona are proposed to explain this difference.
