我们报告了使用 ROSAT 上的位置敏感比例计数器和广域相机获得的射电脉冲星 PSR 0950+08 的观测结果。在0.08-2.4keV能量范围内，背景校正计数率被确定为0.0069±0.0012计数s -1 。导出的光谱可以适合黑体模型和通过星际吸收修改的幂律模型。 2.6×10 6 K 的最佳拟合表面温度和 PSR 0950+08 的年龄（∼1.7×10 7 年）意味着如果排放是热的，则正在发生某种形式的加热过程。发射区域的小隐含尺寸（半径≤20 m）指向某种形式的极帽加热，尽管在可用的模型中，只有 Arons 提出的槽隙模型也许可以解释观测到的光度
We report on observations of the radio pulsar PSR 0950+08 obtained using the Position Sensitive Proportional Counter and Wide Field Camera on board ROSAT. The background-corrected count rate is determined to be 0.0069±0.0012 count s −1 in the 0.08-2.4 keV energy range. The derived spectrum could be fitted to both blackbody and power-law models modified by interstellar absorption. The best-fitting surface temperature of 2.6×10 6 K and the age of PSR 0950+08 (∼1.7×10 7 yr) imply that some form of heating process is occurring if the emission is thermal. The small implied size of the emission region (radius ≤20 m) points towards some form of polar-cap heating, although of the models available only the slot-gap model proposed by Arons can perhaps account for the observed luminosity
