1984)のモデルに従い、相対論的効果をいれたイメージと偏光を計算した。その結果、NebulaはLip型のイメージとなり、Chandraによる観測(Ring型イメージ)と合わなかった。また、Nebula全体の平均偏光度がX線2〜5keVでP〜50％、P.A.〜132度であった。これはX線偏光観測(Weisskopf et al. 1978)の値、P〜20％と大きく異なる。そこで今回、イメージと偏光の問題を解決するため、KCモデルの磁場がトロイダル磁場と乱れた磁場の和で表せると仮定し計算を行った。その結果、KCモデルの磁場強度のうち約60％の強度を、乱れた磁場が担えば、偏光度とイメージを両方を再現できることが分かった。","subitem_description_type":"Abstract"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
