Suzaku Observations of the Galaxy Cluster 1RXS J0603.3+4214: Implications of Particle Acceleration Processes in "Toothbrush" Radio Relic
Madoka Itahana, Motokazu Takizawa, Hiroki Akamatsu +4
We present the results of Suzaku observations of the galaxy cluster 1RXS J0603.3+4214 with "toothbrush" radio relic. Although a shock with Mach number is expected at t…
X-ray study of the double radio relic galaxy cluster CIZA J2242.8+5301
H. Akamatsu, R. J. van Weeren, G. A. Ogrean +7
Content: We present the results from observations of the merging cluster of galaxies CIZA J2242.8+5301 at =0.192. Aims. To study the physics of gas heating and particle…
Absolute Dimensions of a Flat Hierarchical Triple System KIC 6543674 from the Kepler Photometry
Kento Masuda, Sho Uehara, Hajime Kawahara
Many of the Kepler close binaries are suggested to constitute hierarchical triple systems through their eclipse timing variations (ETVs). Eclipses by the third body in those system…
Lifetime and Spectral Evolution of a Magma Ocean with a Steam Atmosphere: Its Detectability by Future Direct Imaging
Keiko Hamano, Hajime Kawahara, Yutaka Abe +2
We present the thermal evolution and emergent spectra of solidifying terrestrial planets along with the formation of steam atmospheres. The lifetime of a magma ocean and its spectr…
Theoretical Emission Spectra of Atmospheres of Hot Rocky Super-Earths
Yuichi Ito, Masahiro Ikoma, Hajime Kawahara +3
Motivated by recent detection of transiting high-density super-Earths, we explore the detectability of hot rocky super-Earths orbiting very close to their host stars. In the enviro…
