| Research Abstract |
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.
