It has a rotation period of 4.26 seconds and a slow-down rate which implies it has a dipole magnetic field strength higher than all other RRATs. In fact its magnetic field is stronger than the quantum critical limit. Its pulses are the brightest of all the RRATs and of the original 11 sources it has the highest burst rate. It has been observed at X-ray wavelengths in observations using the Chandra and XMM Newton X-ray telescopes where an X-ray spectrum typical of thermal emission from a cooling neutron was observed. Modulation of the X-ray light at the 4.26 second rotation period is also observed indicating that there are hot spots on the surface of the star, i.e. the temperature distribution is not uniform. RRAT J1819-1458 has been monitored since its discovery and has been observed to exhibit glitches, a rotational irregularity seen in many young pulsars and magnetars. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RRAT J1819-1458」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
