Abstract

Observations on the search for pulsed radio emission from the Geminga pulsar and the close isolated neutron star 1RX J1308.6+2127 (RBS 1223) at the frequency of 111 MHz are performed. No pulsed signals are detected from both sources. Upper limits for the average flux density are determined as 0.4–4 mJy for the Geminga pulsar and 1.5–15 mJy for RBS 1223 depending on the assumed duty cycle (0.05–0.5) at the frequency of 111 MHz.

Geminga Pulsar 和 RBS 1223 在 111 MHz 频率的无线电发射

摘要

对 Geminga 脉冲星和近距孤立中子星 1RX J1308.6+2127 (RBS 1223) 在 111 MHz 频率下搜索脉冲射电发射进行了观测。两个来源均未检测到脉冲信号。Geminga 脉冲星的平均通量密度上限确定为 0.4-4 mJy，RBS 1223 确定为 1.5-15 mJy，具体取决于 111 MHz 频率下的假设占空比 (0.05-0.5)。
