Repeating Fast Radio Bursts from Neutron Star Binaries: Multi-band and Multi-messenger Opportunities

Abstract: Recent observations indicate that magnetars commonly reside in merging compact binaries and at least part of fast radio bursts (FRBs) are sourced by magnetar activities. It is natural to speculate that a class of merging neutron star binaries may have FRB emitters. In this work, we study the observational aspects of these binaries -particularly those with FRB repeaters, which are promising multi-band and multi-messenger observation targets of radio telescopes and ground based gravitational wave detectors as th… Show more

“…It is still viable that magnetars could be responsible for events that originate in older stellar populations, via close binary evolution or the accretion-induced collapse of a white dwarf (Moriya 2016;Margalit et al 2019;Kremer et al 2021), although progenitors not involving magnetars could also be at play, especially for repeaters (i.e., a neutron star interacting with a companion; Ioka & Zhang 2020;Lyutikov et al 2020; or accreting black hole binaries; Sridhar et al 2021). It has also been predicted that the mergers of two neutron stars (NSs), which can experience potentially long delay times of several gigayears or more, could produce magnetars that may be indefinitely stable to collapse and eventually produce observable FRBs (Totani 2013;Wang et al 2016;Pan et al 2022). The recent claim of an association between the binary NS merger GW190425 and an FRB 20190425A would be definitive evidence for another such delayed channel (Moroianu et al 2023;Panther et al 2023).…”

“…This scenario has been confirmed by general relativistic magnetohydrodynamic simulations (e.g., Palenzuela et al 2013aPalenzuela et al , 2013bPonce et al 2014;Most & Philippov 2020). Compared with the postmerger multiband emission, radiation signals from the premerger BNS may provide more detailed information about the equation of state for the NSs (Neill et al 2022;Pan et al 2022;Zhang et al 2022) and magnetospheric interaction in a BNS system (Lyutikov 2023;Pan et al 2022;Cooper et al 2023).…”

“…This precision could shed light on the tension between different Hubble constant measurements [15]. Over last few years, a variety of other types of EM emissions were proposed theoretically [47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] or suggested observationally [67][68][69][70] to be associated with BNS, NSBH, and BBH mergers, although they could not be confidently verified. If confirmed, the applications of the bright siren approach will be further widened [71][72][73].…”
