Statistical Relation between Solar Flares and Coronal Mass Ejections with Respect to Sigmoidal Structures in Active Regions
Y. Kawabata, Y. Iida, T. Doi +3
Statistical dependencies among features of coronal mass ejections (CMEs), solar flares, and sigmoidal structures in soft-X-ray images were investigated. We applied analysis methods…
Belle II Technical Design Report
T. Abe, I. Adachi, K. Adamczyk +407
The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade of KEKB is under constructi…
Photospheric Flow Field Related to the Evolution of the Sun's Polar Magnetic Patches Observed by Hinode SOT
Anjali John Kaithakkal, Y. Suematsu, M. Kubo +3
We investigated the role of photospheric plasma motions in the formation and evolution of polar magnetic patches using time-sequence observations with high spatial resolution. The…
Average radial structures of gas convection in the solar granulation
T. Oba, Y. Iida, T. Shimizu
Gas convection is observed in the solar photosphere as the granulation, i.e., having highly time-dependent cellular patterns, consisting of numerous bright cells called granules an…
Detection of Flux Emergence, Splitting, Merging, and Cancellation of Network Fields. II Apparent Unipolar Flux Change and Cancellation
Y. Iida, H. Hagenaar, T. Yokoyama
In this second paper in the series, we investigate occurrence frequencies of apparent unipolar processes, cancellation, and emergence of patch structures in quiet regions. Apparent…
Magnetic Field Structures Triggering Solar Flares and Coronal Mass Ejections
K. Kusano, Y. Bamba, T. T. Yamamoto +3
Solar flares and coronal mass ejections (CMEs), the most catastrophic eruptions in our solar system, have been known to affect terrestrial environments and infrastructure. However,…
