PSR B1133 +16:无线电发射高度和等离子体成分

PSR B1133+16: radio emission height and plasma composition

P B Jones

摘要:

Hassall等人最近对LOFAR的操作对该脉冲星40 MHz发射区的大小和高度产生了严重的限制。结果表明,这些限制,给出了有限数量的无懈可击的假设,证明了电子-正电子等离子体不能的排放源。由质子和离子组成的物理上可接受的等离子体源在具有正共转极冠电荷密度的电子束中自然产生。接受这一点将大大澄清整个脉冲星类型的分类。

英文摘要:

Recent operation of LOFAR by Hassall et al has produced severe constraints on the size and altitude of the 40 MHZ emission region in this pulsar. It is shown that these limits, given a limited number of unexceptionable assumptions, demonstrate that an electron-positron plasma cannot be the source of the emission. A physically-acceptable plasma source composed of protons and ions arises naturally in pulsars having positive corotational polar-cap charge density. Acceptance of this would greatly clarify the classification of pulsar types within the whole.
