  4. <700eV Supernovae • Extragalactic supernovae • SN1978K (NGC1313) • detected with ROSAT, ASCA (not Einstein) • type II SN in origin • spectrum: power-law (G~2.2) or thermal (kT=3keV,Z=0.2) • shock acceleration ? pulsar emission ? reverse shock ?

  5. SN1987A (LMC) • X-ray intensity increases during ASCA observations • SIS spectrum can be better fitted with NEI model logt~9.8

  6. 8days! • SN1993J • SN1993J は超新星爆発後 8 日後から観測できた。 • 鉄輝線が観測された。ライトカーブから reverse shock 起源  ミキシング ! DE > DE(optical)  6.4 keV の混入? • 自己相似解を用いて reverse shock & blast wave からの輻射を説明することができた。また reverse shock が晴れ上がるようすがみえた • 1995 年以後、「フロントショック」「リバースショック」などは暗くなったが、パルスサーチなどが継続して行われている。 • 2000年現在は、超新星爆発の内側が見えてくる、いわゆる「晴れ上がり」の時期に相当すると予測されている。 (shigeyama et.al 「1998年以後」) • この時、超新星内部で何が起きているかは謎が多いが、X線が観測されるとすれば、以下のようなことが考えられる。 • 1. 中心に新しいパルサーが誕生のパルス • 2. パルスではなくても、パルサーにより照射されたejecta からの輻射 • この「晴れ上がり」の観測は、超新星爆発と、新しい超新星残骸の間をつなぐ重要なデータとなる。 • upper limit でも、「爆発 7 年後」の輻射の強度を知ることは重要。

  25. Remaining Problems • Low cosmic abundance • ASCA can determine only relative abundance • To determine absolute value, need to detect C, N, O emission lines • Some hints are to consider the thermal structure of remnant • Plasma code • need more resolving power than ASCA/SIS • Chandra emission line project • no need further ASCA observations • no need further ASCA observations

  26. Remaining Problems • Thermal equilibrium • Several methods
