Very very impressive. High res optical imaging is going to be a huge growth area in the coming years. Can't wait to see what mysteries the technique helps to unearth…

"Solacious B FRAUD! FRAUD! FRAUD."

Spectacularly feeble and childish comeback after getting slammed for your false accusations, sunshine.

Hey Mr.Oblivious
Why the silence and the lack of posturing now, eh?
I think you may owe me an apology don't you think?
You have been caught once again. Again you keep missing the target! Your out of your depth — so it might be better idea to keep those lips a bit more zipped instead of putting your foot in it.
Appreciate the support astroron, Ron, or whatever your name is.
Also I suggest you please MYOB.
Thank you for your sincere co-operation.

Sorry. The text written here IS my own, and was not at all plagiarised. (At least I'm happy to play with others!)

After just watching the "80 Telescopes around thev World" webcast about the VLTI, I feel even more interested in the technology necessary to make these observations in the first place. Like the also-noted Gravitational Wave observatories, VLTI is very sensitive to disruptions in the the locality of the apparatus. While VLTI is now able to show concrete results of its' labors, GW observatories are still waiting for a confirmable signal, the wait will be hopefully short (notwithstanding the views of PU, EU, PC etc.). Bring on the GWs!

I have actually unconditionally gave Salacious B. Crumb my complete permission to use this information as he saw fit. Also "Southern Astronomical Delights" is not a book but in fact is my own website.
This actual text you talk about here does NOT appear in my "Southern Astronomical Website" at all. I think you will find this is true looking at my article on "The Orion Nebula: at http://homepage.mac.com/andjames/Page204.htm
(I have added an Open Note at the bottom of this same page verifying this information is true for you.)

The words in his response are, as far as I know, were actually his own and as such was not plagiarised from me at all.

Thanks should be extended to Salacious B. Crumb for pointing the open concern within this post.
I stand quite happy to be able correct the misunderstanding.

Solacious B….FRAUD!!

Very nice plagerism… you are almost good at it. You should at least give the real person the credit.

Every bit of what was posted by this fraud was the work of Andrew James in the book "Southern Astronomical Delights".

In fact, another person who posted this same information did give A. James credit at: http://www.iceinspace.com.au/forum/showthread.php?p=426020

Shame…shame. We always knew you didn't do your own work… just based on how your grammar changed. Now there is DBO proof.

SalBC=Thank you for the data, it is interesting how technology keeps improving, and able to separate stars relatively close together so far away.

Using the distance to the Orion Nebula as 389 parsecs or 1270 +/- 76 light-years, means that the trig. parallax is 2.571 mas (milliarcsec.)

If the principal stars in the Trapezium are; (based on the relative position of STF 748A at 6.55V magnitude)

Star ……. ". mag Spec Class

STF 748 AB 08.9 7.49 O7 B1V
STF 748 AC 13.1 5.06 O7
STF 748 AD 21.5 6.38 B0.5V
STF 748 AE 04.5 11.1 O7

Then the projected distances in AU and light years between the components from A (Mabs=-1.4 Mass=4.5 Solar Masses) is;

B= 3462 AU (0.055 ly.) Mabs =-1.4; 3.6 Solar Masses
C= 5095 AU (0.081 ly.) Mabs =-2.9; 6.4 Solar Masses
D= 8362 AU (0.132 ly.) Mabs =-1.6; 4.7 Solar Masses
E= 1750 AU (0.028 ly.) Mabs =+3.2; 1.5 Solar Masses

In physical size, therefore for the Trapezium is about 10,000 AU across.
The largest estimated minimum orbital period of these stars is about 250,000 years. (about 2.5 times that of Alpha Centauri AB to Proxima) This augers well with the fractional movements so far observed with these stars.
You could compare these values with the older ones described in the dated "Burnham's Celestial Handbook" Vol.2 "Orion" on Theta Orionis.

Note: If value were between 1400 to 1600 light years, these projected separations would be slightly larger.

actually, now that I think of it, I should be able to work it out for myself…..

"the angular distance between the two stars was only about 20 milliarcseconds"
how much is the distance between the two in AU, I wonder?

Congratulations to all the scientists and engineers of the VLTI team. These early proof-of-concept show that VLTI and other interferometry programs around the world can indeed function reliably enabling astronomers to explore objects at a much greater scale than was ever before possible. Who knows what discoveries lie ahead in the field of astronomical interferometry?
