## Results of central mass variation for S2 orbit

Many thanks, these results show that the S2 orbit is described by m = 0.9877, a constant. The Schwarzschild function gives wildly incorrect results, and it seems that the orbit is nearly elliptical. The Einsteinian precession has not been observed experimentally. This is very good numerical work by Horst Eckardt and there is intense interest in the latest UFT papers.

Results of central mass variation for S2 orbit
To: Myron Evans <myronevans123>

I did a calculation with constant m=0.9877. Using the Newtonian “experimental” central mass, then more or less the results of the “best fit” are reproduced. This means, this m function reproduced the full set of orbit parameters:

`M=8.3627*10^36 /* best fit */`
`T=16.07 eps=0.88323 rmin=1.79530e13 rmax=2.89596e14 dphi=5.7710e-4`
`M=8.572*10^36 /*exp. data used*/`
`T=9.65 eps=0.83724 rmin=1.79520e13 rmax=2.02688e14 dphi=6.0636e-4`
`M=8.572*10^36 /*exp. data with m=0.9877*/`
`T=16.07 eps=0.88332 rmin=1.79530e13 rmax=2.89596e14 dphi=5.9144e-4`

Using the Einsteinian m=1-r0/r gives desastrous results, the orbit period shrinks by a factor 10 or so. Reducing the term r0/r by a factor 100:

m = 1 – 0.01*r0/r

still gives half the orbit period only, although the correction to unity is extremely small. The sign of the correction has to be changed to arrive at the experimental T=16.05 y.
Using the extended version

m = 1 – r0/r – alpha/r^2

with alpha>0 worsens the result as expected. With alpha=-2.25e23 m the experimental orbit period can roughly be reproduced, but there is a huge precession of about 1/3*2 pi.

Will try other m functions. The orbit seem to be very sensitive to dm/dr.

Results of central mass variation for S2 orbit

Many thanks. This is a clear and logical method of finding the optimal mass about which S2 orbits. The graphs show the dependence of T on M, the dependence of the eccentricity on M, and the dependence of rmax on M. They all show that the orbit is not Newtonian. I would suggest a computation of the orbit of S2 for the optimal mass M found with Horst’s method. This would be the rigorous computation from
