27 Jun 2002 | Journal: | Astron.Astrophys. 404 (2003) L21 | Subject: | astro-ph | Abstract: | We find evidence that the two high frequency QPOs in Sco X-1 are, more often than not, approximately in the 2:3 frequency ratio familiar from studies of black hole candidates (e.g., XTE J1550-564, Remillard et al. 2002). This implies that the double kHz QPO phenomenon in neutron stars has its origin in properties of strong-field gravity and has little to do with the rotation of a stellar surface or any magnetic field structure anchored in the star. | Source: | arXiv, astro-ph/0206490 | Services: | Forum | Review | PDF | Favorites |
