Abstract

Observations in the high energy radiations from the X-ray to soft gamma-ray bands are one of the important probes to see the nature of Type Ia supernovae, such as progenitor types, explosion mechanisms and nucleosynthesis there, etc. After the loss of the X-ray observatory Hitomi, no gamma-ray missions covering the soft gamma-ray lines from 56Ni nuclei are newly planned at this moment and near future X-ray missions in 2020s are mainly focused on the soft X-ray band below 10 keV, where super-high energy-resolution spectroscopy will be available with the micro-calorimeter array by such as X-ray Astronomical Recovery mission (XARM) within five years or so. One of the scientific targets could be the fluorescent K lines from metals impacted by recoil electrons via Compton scattering and/or possible 5.9 keV lines from 55Fe. In this presentation, near future X-ray observatories including hard X-ray mission plans are reviewed, and the feasibilities of their observational approaches are summarized.
