Supernovae in binaries, runaway stars, neutron star kicks and kinematic ages

我们将通过追溯中子星的飞行路径到它们在超新星(SN)中的发源地来研究中子星的起源。当过去的飞行路径穿过OB关联时，和/或当一颗中子星和一颗逃逸恒星同时在同一地点时，可以找到SN位置，从而为释放两颗恒星的双星中的SN提供证据。此外，我们将在SN残骸中系统地寻找任何光谱类型的逃逸恒星。我们将研究双星中近地天体的动力学和运动学，包括自旋-踢腿对准。中子星的飞行时间作为运动年龄，也是一个比特征自旋年龄更好的年龄约束；两者的比较使我们能够得出中子星的初始自转周期和/或制动指数。我们还利用新技术，如与LEAP或Meerkat的联合成像/计时观测，寻找新的合适的中子星(主要是射电脉冲星)。

We will investigate the origin of neutron stars by tracing back their flight path to their place of origin in a supernova (SN). The SN location can be found either, when the past flight path crosses an OB association, and/or when a neutron star and a runaway star were at the same time at the same place, hence providing evidence for a SN in a binary releasing both stars. Furthermore, we will systematically search for runaway stars of any spectral type in SN remnants. We will study the dynamics and kinematics of SNe in binaries including the spin-kick alignment. The flight time of the neutron star, as kinematic age, is also a better age constraint than the characteristic spin-down age; the comparison of both enables us to derive the initial spin period and/or the braking index of the neutron star. We also search for new suitable neutron stars (mainly radio pulsars) with novel techniques such as joint imaging/timing observations with LEAP or MeerKAT.
