摘要: A new X-ray source, XTE J1855-026, was discovered during Rossi X-Ray Timing Explorer (RXTE) scans along the Galactic plane. The source shows pulsations at a period of 361 s and also modulation 6.1 days, which we interpret as orbital system. spectrum above ~3 keV can be fitted with an absorbed power-law model high-energy cutoff iron emission line approximately 6.4 keV. We these results indicating that J1855-026 is likely to consist neutron star accreting from wind O or B supergiant primary. less interpretation instead Be/neutron binary, in case it would have shortest known for such
