Science operation, data handling, and ground support system of the SOLAR-C mission
Shin Toriumi, Mari Nishiyama, Keiichi Matsuzaki +16
SOLAR-C is an international solar-observing satellite mission led by Japan Aerospace Exploration Agency (JAXA). It aims to elucidate mass and energy transport in solar atmospheres…
Reconstructing the XUV Spectra of Active Sun-like Stars Using Solar Scaling Relations with Magnetic Flux
Kosuke Namekata, Shin Toriumi, Vladimir S. Airapetian +3
Kepler Space Telescope and Transiting Exoplanet Survey Satellite unveiled that Sun-like stars frequently host exoplanets. These exoplanets are subject to fluxes of ionizing radiati…
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…
Nowcast of an EUV dynamic spectrum during solar flares
Toshiki Kawai, Shinsuke Imada, Shohei Nishimoto +2
In addition to X-rays, extreme ultraviolet (EUV) rays radiated from solar flares can cause serious problems, such as communication failures and satellite drag. Therefore, methods f…
Statistical Study of Solar White-light Flares and Comparison with Superflares on Solar-type Stars
Kosuke Namekata, Takahito Sakaue, Kyoko Watanabe +9
Recently, many superflares on solar-type stars were discovered as white-light flares (WLFs). A correlation between the energies (E) and durations (t) of superflares is derived as $…
Statistical Studies of Solar White-Light Flares and Comparisons with Superflares on Solar-type Stars
Kosuke Namekata, Takahito Sakaue, Kyoko Watanabe +9
Recently, many superflares on solar-type stars have been discovered as white-light flares (WLFs). The statistical study found a correlation between their energies () and duratio…
Characteristics that Produce White-Light Enhancements in Solar Flares Observed by Hinode/SOT
Kyoko Watanabe, Jun Kitagawa, Satoshi Masuda
To understand the conditions that produce white-light (WL) enhancements in solar flares, a statistical analysis of visible continuum data as observed by Hinode/Solar Optical Telesc…
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…
Validation of a Scaling Law for the Coronal Magnetic Field Strengths and Loop Lengths of Solar and Stellar Flares
Kosuke Namekata, Takahito Sakaue, Kyoko Watanabe +2
Shibata & Yokoyama (1999, 2002) proposed a method of estimating the coronal magnetic field strengths () and magnetic loop lengths () of solar and stellar flares, on the basis…
No Evidence of Intrinsic Optical/Near-Infrared Linear Polarization for V404 Cygni During its Bright Outburst in 2015: Broadband Modeling and Constraint on Jet Parameters
Y. T. Tanaka, R. Itoh, M. Uemura +39
We present simultaneous optical and near-infrared (NIR) polarimetric results for the black hole binary V404 Cygni spanning the duration of its 7-day long optically-brightest phase…
GEOTAIL observation of the SGR1806-20 Giant Flare: The first 600 ms
Toshio Terasawa, Yasuyuki Tanaka, Yasuhiro Takei +14
On December 27, 2004, plasma particle detectors on the GEOTAIL spacecraft detected an extremely strong signal of hard X-ray photons from the giant flare of SGR1806-20, a magnetar c…
