论文摘要
遵循Pol等人所述的过程,我们通过包括新的,高度古怪的DNS系统J0509+3801来更新银河系双中性星(DNS)合并率(Lynch等人)。这导致了$ \ mathcal {r} _ {\ rm mw} = 37^{+24} _ { - 11} $ myr $^{ - 1} $的新的银河系合并率$ \ Mathcal {rm} _ {\ rm mw} = 37^{+24},其中错误表示90%的置信区间。高级LIGO的相应DNS合并检测率为$ \ MATHCAL {R} = 1.9^{+1.2} _ { - 0.6} \ times \ left(d _ {\ rm rm r} / 100 \ \ \ \ \ \ \ \ \ \ rm mpc \ rm mpc \ right) 距离。使用LIGO O3范围130 MPC(Abbott等人),我们预测Ligo每年在O3敏感性下观察到三到七个DNS合并。
Following the procedure described in Pol et al., we update the Galactic double neutron star (DNS) merger rate by including the new, highly eccentric DNS system J0509+3801 (Lynch et al.). This leads to a new Galactic DNS merger rate of $\mathcal{R}_{\rm MW} = 37^{+24}_{-11}$ Myr$^{-1}$, where the errors represent 90% confidence intervals. The corresponding DNS merger detection rate for Advanced LIGO is $\mathcal{R} = 1.9^{+1.2}_{-0.6} \times \left( D_{\rm r} / 100 \ \rm Mpc \right)^3 \rm yr^{-1},$ where $D_{\rm r}$ is the range distance. Using the LIGO O3 range distance of 130 Mpc (Abbott et al.), we predict that LIGO will detect anywhere between three and seven DNS mergers per year of observing at O3 sensitivity.
