Pc. Fragile et Gj. Mathews, Reconstruction of stellar orbits close to Sagittarius A*: Possibilities for testing general relativity, ASTROPHYS J, 542(1), 2000, pp. 328-333
We have reconstructed possible orbits for a collection of stars located wit
hin 0."5 of Sgr A*. These orbits are constrained by observed stellar positi
ons and angular proper motions. The construction of such orbits serves as a
baseline from which to search for possible deviations due to the unseen ma
ss distribution in the central 1000 AU of the Galaxy. We also discuss the l
ikelihood that some of these stars may eventually exhibit detectable relati
vistic effects, allowing for interesting tests of general relativity around
the 2.6 x 10(6) M. central object.
