1999A&A...351L..33O

A new pulsar, 1SAX J1452.8-5949, was discovered during a BeppoSAX galactic plane survey on 1999 July 20 at R.A.=14^h52^m49.3s, Dec=-59°49'18'' (J2000) with a 90% confidence uncertainty radius of 50''. Coherent pulsations were detected with a barycentric period of a 437.4±1.4s. The X-ray spectrum can be modeled by a power-law with a photon index of 1.4±0.6 and absorption consistent with the galactic value in the direction of the source (1.9x10²²atom/cm²). An Fe K line with a equivalent width of 1.3keV may be present in the spectrum. The unabsorbed 2-10 keV flux is 9x10^–13erg/cm²/s. The X-ray properties and lack of an obvious optical counterpart are consistent with a Be star companion at a distance of between approximately 6 and 12kpc which implies a luminosity of (4-15)x10³³erg/s.
