    <title>Abstract</title>
    We report on multi-wavelength monitoring observations of an M-dwarf flare star AD Leonis with the Seimei Telescope (6150–7930 Å), SCAT (Spectroscopic Chuo-university Astronomical Telescope; 3700–7500 Å), and NICER (Neutron Star Interior Composition Explorer; 0.2–12.0 keV), with the collaboration of the OISTER (Optical and Infrared Synergetic Telescopes for Education and Research) program. Twelve flares are detected in total, including ten Hα, four X-ray, and four optical-continuum flares; one of them is a superflare with a total energy of ∼2.0 × 1033 erg. We found that: (1) during the superflare, the Hα emission line full width at 1/8 maximum dramatically increases to 14 Å from 8 Å in the low-resolution spectra (R ∼ 2000) accompanied by large white-light flares, (2) some weak Hα/X-ray flares are not accompanied by white-light emissions, and (3) the non-flaring emissions show clear rotational modulations in X-ray and Hα intensity in the same phase. To understand these observational features, one-dimensional hydrodynamic flare simulations are performed using the RADYN code. We find the simulated Hα line profiles with hard and high-energy non-thermal electron beams to be consistent with the initial phase line profiles of the superflares, while those with a softer and/or weak-energy beam are consistent with those in decay phases, indicating the changes in the energy fluxes injected to the lower atmosphere. Also, we find that the relation between the optical continuum and Hα intensity is nonlinear, which can be one cause of the non-white-light flares. The flare energy budget exhibits diversity in the observations and models, and more observations of stellar flares are necessary for constraining the occurrence of various emission line phenomena in stellar flares.

    Extending the earlier measurements reported in Hitomi collaboration (2016, Nature, 535, 117), we examine the atmospheric gas motions within the central 100 kpc of the Perseus cluster using observations obtained with the Hitomi satellite. After correcting for the point spread function of the telescope and using optically thin emission lines, we find that the line-of-sight velocity dispersion of the hot gas is remarkably low and mostly uniform. The velocity dispersion reaches a maxima of approximately 200 km s(-1) toward the central active galactic nucleus (AGN) and toward the AGN inflated northwestern &quot;ghost&quot; bubble. Elsewhere within the observed region, the velocity dispersion appears constant around 100 km s(-1). We also detect a velocity gradient with a 100 km s(-1) amplitude across the cluster core, consistent with large-scale sloshing of the core gas. If the observed gas motions are isotropic, the kinetic pressure support is less than 10% of the thermal pressure support in the cluster core. The well-resolved, optically thin emission lines have Gaussian shapes, indicating that the turbulent driving scale is likely below 100 kpc, which is consistent with the size of the

    The present paper explains the temperature structure of X-ray emitting plasma in the core of the Perseus cluster based on 1.8-20.0 keV data obtained with the Soft X-ray Spectrometer (SXS) on board the Hitomi Observatory. A series of four observations was carried out, with a total effective exposure time of 338 ks that covered a central region of similar to 7&#039; in diameter. SXS was operated with an energy resolution of similar to 5 eV (full width at half maximum) at 5.9 keV. Not only fine structures of K-shell lines in He-like ions, but also transitions from higher principal quantum numbers were clearly resolved from Si through Fe. That enabled us to perform temperature diagnostics using the line ratios of Si, S, Ar, Ca, and Fe, and to provide the first direct measurement of the excitation temperature and ionization temperature in the Perseus cluster. The observed spectrum is roughly reproduced by a single-temperature thermal plasma model in collisional ionization equilibrium, but detailed line-ratio diagnostics reveal slight deviations from this approximation. In particular, the data exhibit an apparent trend of increasing ionization temperature with the atomic mass, as well as smal

    We present multi-epoch X-ray spectral observations of three Type IIn supernovae (SNe), SN 2005kd, SN 2006jd, and SN 2010jl, acquired with Chandra, XMM-Newton, Suzaku, and Swift. Previous extensive X-ray studies of SN. 2010jl have revealed that X-ray spectra are dominated by thermal emission, which likely arises from a hot plasma heated by a forward shock propagating into a massive circumstellar medium (CSM). Interestingly, an additional soft X-ray component was required to reproduce the spectra at a period of similar to 1-2 years after the SN explosion. Although this component is likely associated with the SN, its origin remained an open question. We find a similar, additional soft X-ray component from the other two SNe IIn as well. Given this finding, we present a new interpretation for the origin of this component; it is thermal emission from a forward shock essentially identical to the hard X-ray component, but directly reaches us from a void of the dense CSM. Namely, the hard and soft components are responsible for the heavily and moderately absorbed components, respectively. The co-existence of the two components with distinct absorptions as well as the delayed emergence of th

    近年、太陽フレアのさらに10-10000 倍ものエネルギーを放出するフレア(スーパーフレアと呼ばれる)が恒星の可視光観測で発見されている(例えば Maehara et al. 2012 Nature など)。このスーパーフレアが太陽でもし起これば、地球規模の大停電やオゾン層破壊など、我々の社会に多大な打撃が加わると考えられている。本研究では、発生頻度の少ない巨大フレアをキャッチする能力の高い全天X 線監視装置MAXI を用いて、(1)全天方向に対してスーパーフレアサーチをX 線帯域で行い、(2)星の若さや生成環境と、スーパーフレアの頻度との関係を明らかにする。また(3)フレアループの幾何、位置に新たな情報を与える偏光に高い感度を持つ光学系の開発を行う。

    (1) We obtained the proof that a Class 0 candidate emits X-rays. (2) In order to access the origin and the geometry of protostars by detecting flares from them, we investigated key parameters for a flare on stars. Using the Monitor of All-sky X-ray Image (MAXI), we searched huge X-ray flares on stars, and obtained the dependence of flare frequencies with flare energy and the relation of flare energy to the stellar spot size, ranging ten orders of magnitude, from small solar flares to huge stellar flares. (3) In a multi-wavelength observation of II Peg, we detected a huge version of two-ribbon flare. (4) We established a way to bend crystals by depositing Diamond Like Carbon on the surface of them. The bent crystals can be an X-ray imaging poralimetry which makes use of Bragg reflection. We also confirmed that the optics can converge X-ray beam.

    Grant amount: \4420000 ( Direct Cost: \3400000 、 Indirect Cost: \1020000 )

    We detected hard X-ray emissions from protostars which are embedded in deep inside of molecular cores, and obtained physical properties (X-ray luminosities, time variabilities, plasma temperatures, etc.). We confirmed youth of the sources using infrared band data obtained with Spitzer satellite. In order to compare with X-ray properties, we also observed stellar sources with different phases and masses, and studied X-ray emitting mechanisms and acceleration of stellar winds. We further studied flare activities (flare frequencies, plasma temperatures, etc.) with extremely large X-ray luminosities, using the all-sky monitor "MAXI". We developed optics which has sensitivity for X-ray polarization.
