A Solar Magnetic-fan Flaring Arch Heated by Non-thermal Particles and Hot Plasma from an X-ray Jet Eruption

Kyoung-Sun Lee, Hirohisa Hara, Kyoko Watanabe +10

We have investigated an M1.3 limb flare, which develops as a magnetic loop/arch that fans out from an X-ray jet. Using Hinode/EIS, we found that the temperature increases with heig…

Locating Hot Plasma in Small Flares using Spectroscopic Overlappogram Data from the Hinode {\it EUV} Imaging Spectrometer

Louise Harra, Sarah Matthews, David Long +6

One of the key processes associated with the "standard" flare model is chromospheric evaporation, a process where plasma heated to high temperatures by energy deposition at the fla…

Plasma evolution within an erupting coronal cavity

David M. Long, Louise K. Harra, Sarah A. Matthews +5

Coronal cavities have previously been observed associated with long-lived quiescent filaments and are thought to correspond to the associated magnetic flux rope. Although the stand…

Study on Precursor Activity of the X1.6 Flare in the Great AR 12192 with SDO, IRIS, and Hinode

Y. Bamba, K. S. Lee, S. Imada +1

The physical properties and its contribution to the onset of solar flare are still unclear although chromospheric brightening is considered a precursor phenomenon of flare. Many st…

IRIS, Hinode, SDO, and RHESSI observations of a white light flare produced directly by non-thermal electrons

Kyoung-Sun Lee, Shinsuke Imada, Kyoko Watanabe +2

An X1.6 flare occurred in AR 12192 on 2014 October 22 at 14:02 UT and was observed by Hinode, IRIS, SDO, and RHESSI. We analyze a bright kernel which produces a white light (WL) fl…

Photospheric Abundances of Polar Jets on the Sun Observed by Hinode

Kyoung-Sun Lee, David H. Brooks, Shinsuke Imada

Many jets are detected at X-ray wavelengths in the Sun's polar regions, and the ejected plasma along the jets has been suggested to contribute mass to the fast solar wind. From in-…
