Issue Date: | 2022 | Journal: | NATURE | Number: | 602 | Issue: | 7898 | First Page: | 585 | Abstract: | Fast radio bursts (FRBs) are flashes of unknown physical origin<SUP>1</SUP>. The majority of FRBs have been seen only once, although some are known to generate multiple flashes<SUP>2,3</SUP>. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission<SUP>4,5</SUP>. Recently, the discovery<SUP>6</SUP> of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths<SUP>6</SUP>. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system<SUP>7</SUP>. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts. | URI: | http://hdl.handle.net/20.500.12386/32549 | URL: | https://www.nature.com/articles/s41586-021-04354-w | ISSN: | 0028-0836 | DOI: | 10.1038/s41586-021-04354-w | Bibcode ADS: | 2022Natur.602..585K | Fulltext: | open |
