Solar Soft X-ray Coronal Dimming in a Failed Eruption Associated with Plasma Cooling

Xinyue Wang, Astrid M. Veronig, Hechao Chen +1

Coronal dimmings are observed as sudden and localized reductions in the extreme-ultraviolet and X-ray emission of the solar corona. Traditionally, significant dimmings of spectral…

Intense but Harmless: Exo-Space Weather Around an M Dwarf with a Single-Hemisphere Dynamo

Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian +4

M dwarfs are among the most promising host stars in the search for habitable exoplanets. However, their active atmospheres drive intense magnetic activity, including energetic flar…

Coronal dimmings and what they tell us about solar and stellar coronal mass ejections

Astrid M. Veronig, Karin Dissauer, Bernhard Kliem +10

Coronal dimmings associated with coronal mass ejections (CME) from the Sun have gained much attention since the late 1990s when they were first observed in high-cadence imagery of…

Simulations of coronal mass ejections on a young solar-type star and their detectability through coronal spectral observations

Yu Xu, Hui Tian, Julián D. Alvarado-Gómez +2

There is a growing interest in searching for coronal mass ejections (CMEs) in other stellar systems because they are thought to be one of the important factors shaping planetary at…

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

Yu Xu, Julián D. Alvarado-Gómez, Hui Tian +3

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 sta…

Sun-as-a-star observations of obscuration dimmings caused by filament eruptions

Yu Xu, Hui Tian, Astrid M. Veronig +1

Filament eruptions often lead to coronal mass ejections (CMEs) on the Sun and are one of the most energetic eruptive phenomena in the atmospheres of other late-type stars. However,…

Observations of a white-light flare associated with a filament eruption

Y. L. Song, Y. Guo, H. Tian +3

We present observations of an M5.7 white-light flare (WLF) associated with a small filament eruption in NOAA active region 11476 on 2012 May 10. During this flare, a circular flare…

Observations of white-light flares in NOAA active region 11515: high occurrence rate and relationship with magnetic transients

Y. L. Song, H. Tian, M. Zhang +1

There are two goals in this study. One is to investigate how frequently white-light flares (WLFs) occur in a flare-productive active region (NOAA active region 11515). The other is…

Multi-episode chromospheric evaporation observed in a solar flare

H. Tian, N. -H. Chen

With observations of IRIS, we study chromospheric heating and evaporation during an M1.6 flare SOL2015-03-12T11:50. At the flare ribbons, the Mg II 2791.59 line shows quasi-periodi…

Hydrogen Lyman emission through the solar cycle

W. Curdt, H. Tian

We present observations and results of radiance and irradiance studies completed by SoHO-SUMER during the past solar cycle. We find that the cycle variation in Ly-alpha irradiance…
