binding energy是在毫秒星系增生的框架内产生的

The binding energy produced within the framework of the accretion of millisecond pulsars

摘要:

研究了束缚能在吸积白矮星(WD)吸积诱导坍缩(AIC)过程中对毫秒双星(MSP)产生的作用和意义。我检查的结合能模型,由于在密切的双系统的动力学过程,并调查可能的质量足以诱导其轨道参数的同伴。这种相互作用的确定性性质对与其初始条件相关的双星系统的状态方程(其中中子星的紧凑性与结合能的量成比例)具有很强的敏感性。这种行为将模拟通常假设的质量和数量的吸积物质下的瞬时质量损失($ΔM \sim 0.18M_{\odot}$)。结果,这将指示由于角动量损失而导致的MSP的引力质量的增加。这样一个系统的结果将是一个循环的二元MSP,其中同伴是一个低质量的WD,从而区分二元形成的情况。此外,本工作的结果可以提供基于吸积率的中子星的预期质量和结合能的约束条件

英文摘要:

The role and implication of binding energy through the accretion-induced collapse (AIC) of accreting white dwarfs (WDs) for the production of millisecond pulsars (MSPs) are investigated. I examine the binding energy model due to the dynamical process in close binary systems and investigating the possible mass of the companion sufficient to induce their orbital parameters. The deterministic nature of this interaction has a strong sensitivity to the equation of state of the binary systems (where the compactness of a neutron star is proportional to the amount of binding energy) associated with their initial conditions. This behavior will mimic the commonly assumed mass and amount of accreted matter under the instantaneous mass loss ($ΔM \sim 0.18M_{\odot}$). As a result, this will indicate an increase in the MSP's gravitational mass due to angular momentum losses. The outcome of such a system will then be a circular binary MSP in which the companion is a low-mass WD, thus distinguishing the binary formation scenarios. In addition, the results of this work could provide constraints on the expected mass and binding energy of a neutron star based on the accretion rate
