Precessing Binary Systems

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>1. Does anyone know anything about Moffat's theory and what it involves?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Many theories abound. I've not heard of this one.

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>2. Are these observations continuing to not fit the relativistic precession values?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

That's right.

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>3. Are the precession values in excess of the relativistic figure or less than?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Less.

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>4. I have seen the relativistic formula for orbital precession many times but I have never seen it expressed for the case of binaries of similar mass. What does it look like in the general case?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

In GR, the mass of the primary is replaced by the sum of the two masses, with no other changes. By contrast, in the Meta Model, a new factor appears equal to the sum of the squares of the masses divided by the square of the sum of the masses. That reduces the discrepancy, but does not eliminate it. The rest of the discrepancy might be eliminated by a gravitational shielding effect. Unfortunately, I don't have quick access to the stellar interior models for these various classes of stars to make the calculations based on the specific formula in <i>Pushing Gravity</i>. -|Tom|-

There's a very good paper outlining the problem and comparing orbital precession data for a number of different binary systems at [url] www.gsanctuary.com/general_relativity.html [/url].

I think this may be the Moffat paper you are referring to -

Thank you one and all for the information. I will have to peruse Pushing Gravity more closely, it is not the kind of book one can absorb in one pass through - at least not for me! I can't help but think that observing the closest and highest density orbiting objects are going to give us critical information about gravity and how it works. I am somewhat curious as to how the conventional astronomers sweep these discordancies under the rug when they are so well documented. I believe DI Herculis has been observed for over 30 years now. How much information do they need?
