A new pulsar , 1SAX J1452.8 - 5949 , was discovered during a BeppoSAX galactic plane survey on 1999 July 20 at R.A.= 14 ^ { h } 52 ^ { m } 49 \aas@@fstack { s } 3 , Dec= -59 ^ { \circ } 49 \hbox { $ { } ^ { \prime } $ } 18 \hbox { $ { } ^ { \prime \prime } $ } ( J2000 ) with a 90 % confidence uncertainty radius of 50 \hbox { $ { } ^ { \prime \prime } $ } .
Coherent pulsations were detected with a barycentric period of a 437.4 \pm 1.4 s. The X-ray spectrum can be modeled by a power-law with a photon index of 1.4 \pm 0.6 and absorption consistent with the galactic value in the direction of the source ( 1.9 \times 10 ^ { 22 } atom cm ^ { -2 } ) .
An Fe K line with a equivalent width of \mathrel { \hbox { \hbox to 0.0 pt { \lower 2.365 pt \hbox { $ \sim$ } } \kern - 3.0 pt \raise 1.72 pt \hbox { $ > $ } } } 1.3 keV may be present in the spectrum .
The unabsorbed 2–10 keV flux is 9 \times 10 ^ { -13 } erg cm ^ { -2 } s ^ { -1 } .
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 12 kpc which implies a luminosity of ( 4–15 ) \times 10 ^ { 33 } erg s ^ { -1 } .
