Detection of a high-velocity prominence eruption leading to a CME associated with a superflare on the RS CVn-type star V1355 Orionis

Shun Inoue, Hiroyuki Maehara, Yuta Notsu +5

Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase…

Hunting for stellar coronal mass ejections

Kosuke Namekata, Hiroyuki Maehara, Satoshi Honda +3

Solar flares are often accompanied by filament/prominence eruptions, sometimes leading to coronal mass ejections (CMEs). By analogy, we expect that stellar flares are also associat…

Space Plasma Physics: A Review

Bruce T. Tsurutani, Gary P. Zank, Veerle J. Sterken +13

Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent solar wind, together with sporadic solar eruptions, introduces various space plasma pr…

Sun-as-a-star Analysis of H Spectra of a Solar Flare Observed by SMART/SDDI: Time Evolution of Red Asymmetry and Line Broadening

Kosuke Namekata, Kiyoshi Ichimoto, Takako T. Ishii +1

Stellar flares sometimes show red/blue asymmetries of H line, which can indicate chromospheric dynamics and prominence activations. However, the origin of asymmetries is not com…

Extreme solar events

Edward W. Cliver, Carolus J. Schrijver, Kazunari Shibata +1

We trace the evolution of research on extreme solar and solar-terrestrial events from the 1859 Carrington event to the rapid development of the last twenty years. Our focus is on t…

Discovery of a Long-Duration Superflare on a Young Solar-Type Star EK Draconis with Nearly Similar Time Evolution for H and White-Light Emissions

Kosuke Namekata, Hiroyuki Maehara, Satoshi Honda +17

Young solar-type stars are known to show frequent "superflares", which may severely influence the habitable worlds on young planets via intense radiations and coronal mass ejection…
