Revealing Double White Dwarf Mergers with Multi-messenger Signals
文献摘要：
A significant number of double white dwarfs(DWDs)are believed to merge within the Hubble time due to the gravitational wave(GW)emission during their inspiraling phase.The outcome of a DWD system is either a type la Supernova as the double-degenerate model,or a massive,long-lasting merger remnant.Expected multi-messenger signals of these events will help us to distinguish detailed merging physical processes.In this work,we aim to provide a generic scenario of DWD merging,investigate the emission of all major messengers,with a focus on GWs and neutrinos.Our goal is to provide some guidance for current and future(collaborative)efforts of multi-messenger observations.Throughout the merging evolution of a DWD system,different messengers(GW,neutrino and electromagnetic wave)will dominate at different times.In this work,we show that DWD merger events located at the distance of 1 kpc can indeed produce detectable signals of GWs and neutrinos.The GW frequency is in 0.3-0.6 Hz band around 10 days before tidal disruption begins.We estimate that in optimistic situations,the neutrino number detected by upcoming detectors such as JUNO and Hyper-Kamiokande can reach O(1)for a DWD merging event at～1 kpc.
