Didn't someone in this thread mention a little program that lets you plot the barycentre of a system? Could we try sticking in a Neptune mass planet and the brown dwarf planet barbi into that?

Thanks Jim! This seems to be the lightcurve that Brian Warner already has sent me (he sent it to me in numerical form, as I had requested), but it's helpful to have a graph of it.

Thanks! He was on my list but I didn't have this email address!

Re: lightcurves for 947 Monterosa and 1717 Arlon

Dear Mr. Stephens:

I am calculating the rotation axes of 947 Monterosa and 1717 Arlon. I want all existing lightcurves.

I see 1717 Arlon listed on your website. Would you send me the lightcurve in numerical form? Brian Warner recently sent me a lightcurve on Monterosa, in such form, and it was satisfactory.

Sincerely,
Joseph C. Keller

Hi Joe, off the subject but I thought I'd best stick this down here before I forget it. From looking at the esu and its relationship to gravity, I get Q^2 = 4G h^2 b / r^2 k

Where b is the speed of gravity.

Rearranging for b I get a lightly lower speed of gravity than I think it is but I haven't worked it out to many decimal places.

With the numbers I've used (1.602E-19)^2 = 4 *6.678E-11 * (6.626E-34)^2 * b / (2.4E-12)^2 *9E 9
The speed of gravity comes out as about 1.1344E 25

Putting that speed of gravity into the equation x = c^2 / b^2 the answer differs from h by about point one. I think that's not too bad at all, as I think we could e talking about particles having a form factor, an rms value divided by the average value.

Sorry about the thread interruption.

A question on these asteroids. Asteroids do bang into each other but not like in the movies. Fairly gentle affairs. That has to effect the spins but I'm not too sure about the axis of spin. Not much mass, they should precess, yeah?
