Observation and numerical modeling of chromospheric evaporation during the impulsive phase of a solar flare

Watanabe, Tetsuya; Murakami, Izumi; Imada, Shinsuke

We have studied the chromospheric evaporation flow during the impulsive phase of the flare by using the Hinode/EUV Imaging Spectrometer observation and 1D hydrodynamic numerical simulation coupled to the time-dependent ionization. The observation clearly shows that the strong redshift can be observed at the base of the flaring loop only during the…

3D magnetic field configuration of small-scale reconnection events in the solar plasma atmosphere

Shimizu, T.

The outer solar atmosphere, i.e., the corona and the chromosphere, is replete with small energy-release events, which are accompanied by transient brightening and jet-like ejections. These events are considered to be magnetic reconnection events in the solar plasma, and their dynamics have been studied using recent advanced observations from the H…

Chromospheric anemone jets and magnetic reconnection in partially ionized solar atmosphere

Shibata, K.; Isobe, H.; Singh, K. A. P. +1 more

The solar optical telescope onboard Hinode with temporal resolution of less than 5 s and spatial resolution of 150 km has observed the lower solar atmosphere with an unprecedented detail. This has led to many important findings, one of them is the discovery of chromospheric anemone jets in the solar chromosphere. The chromospheric anemone jets are…
