飞行器的绝对发射高度：PSR B1839 +09、B1916 +14和B2111 +46
Absolute emission altitude of pulsars: PSRs B1839+09, B1916+14 and B2111+46
摘要：
我们研究了多组分谱仪PSR B1839+09、B1916+14和B2111+46的平均谱。我们估计了核心成分的发射高度，从而找到了锥状成分对应的绝对发射高度。通过拟合高斯的发射分量，我们确定的相位位置的分量峰。我们的研究结果表明，这些类星体的发射光束具有嵌套的芯锥结构。基于各分量峰的相位位置，我们估计了轮廓中的像差-延迟（A/R）相移。由于A/R相移，强度分布中的芯分量的峰值和偏振角摆动的拐点被发现以这样的方式相对于双正交平面在相反的方向上对称地移位，即芯向前侧移位，偏振角拐点向后侧移位。利用Gangadhara（2005）给出的A/R相移的精确表达式，我们已经能够确定日冕面的相位位置，并估算出核心和圆锥分量相对于中子星中心的绝对发射高度。
英文摘要：
We study the mean profiles of the multi--component pulsars PSRs B1839+09, B1916+14 and B2111+46. We estimate the emission height of the core components, and hence find the absolute emission altitudes corresponding to the conal components. By fitting Gaussians to the emission components, we determine the phase location of the component peaks. Our findings indicate that the emission beams of these pulsars have the nested core--cone structures. Based on the phase location of the component peaks, we estimate the aberration--retardation (A/R) phase shifts in the profiles. Due to the A/R phase shift, the peak of the core component in the intensity profile and the inflection point of the polarization angle swing are found to be symmetrically shifted in the opposite directions with respect to the meridional plane in such a way that the core shifts towards the leading side and the polarization angle inflection point towards the trailing side. We have been able to locate the phase location of the meridional plane and to estimate the absolute emission altitude of both the core and the conal components relative to the neutron star centre, using the exact expression for the A/R phase shift given by Gangadhara (2005).
