论文摘要
本文在[Phys。莱特牧师。 {\ bf 119}，201103]。我们系统地探索表征祖细胞星的参数空间，状态方程以及核心崩溃事件的标量探测理论。我们确定了由此产生的崩溃事件的非常简单且直接的分类方案。对于任何给定的参数集，塌陷导致三个端状态之一，一个弱标量的中子星，强烈标量的中子星或黑洞，可能在多个阶段形成。后两个端状态可以导致强烈的重力波信号，这些信号在目前的连续波搜索中可以通过基于地面的检测器进行检测。我们在参数空间中确定了一个非常锋利的边界，该边界将强烈的重力波发射与辐射可忽略不计的事件分开。
This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {\bf 119}, 201103]. We systematically explore the parameter space that characterizes the progenitor stars, the equation of state and the scalar-tensor theory of the core collapse events. We identify a remarkably simple and straightforward classification scheme of the resulting collapse events. For any given set of parameters, the collapse leads to one of three end states, a weakly scalarized neutron star, a strongly scalarized neutron star or a black hole, possibly formed in multiple stages. The latter two end states can lead to strong gravitational-wave signals that may be detectable in present continuous-wave searches with ground-based detectors. We identify a very sharp boundary in the parameter space that separates events with strong gravitational-wave emission from those with negligible radiation.
