Even if we're wrong, what's the worst that can happen? You will have to return, or sign over to Chandra/Harvard, the millions you will make for posting your results on the APOD forum.

Thanks for you point of view. When legal issues are on my path, i feel unpleasantly itchy.Case and iampete wrote:"And I would put you and this forum in the {non-commercial} category."

These new data have led to a new set of images.bystander wrote: The Chandra page said the stars were added from AAO2. You might be able to use the same data to get rid of them.
Also, there is a two color xray image on the Chandra page that might provide more insight to the xray data.

I see the close-up by Hubble, and I'm not convinced yet; nothing that looks like a loop.apodman wrote:I see it and I believe.henk21cm wrote:Neufer suggested a smoke ring ... the yellow circle is seen almost 'edge on'.
Well, believing is still a little short of being convinced (the way I'm using the language today, anyway).Case wrote:I'm not convinced yet
Exactly, so some parts of the far side should be visible. Lacking that, there may not be a far side.apodman wrote:but the far part appears here and there and obscured.
Correct. In an earlier comment i pointed out that -although not impossible- it is rather unlikely that the alignment is exactly edge on. Since this type of explosions is not uncommon, at least there must a dozen of similar structures visible, in which we can see the entire smoke ring. I have never seen such images (which is no proof that they do not exist).Case and Apodman wrote:Exactly, so some parts of the far side should be visible. Lacking that, there may not be a far side.
I don't think so. During the red giant phase, the companion's core would be fusing helium at very high temperature, so when it lost its outer layer due to the blast wave, the exposed core should be shining very brightly and should remain that way even in the last thousand years. We need to find a bow shock somewhere inside the supernova remnant that would show the location of the speeding core plowing through the inside.neufer wrote: There may well be nothing left but an insignificant (and hard to find) brown dwarf

I'm not convinced of the permanence of the "fill in" of the inside of the disk. It seems to me that the deflected material would continue to move outwards, but at varying (but still very small) angles from radially outward (dependent on the amount of deflection). Any material that changed its radially outward path to "fill in" the inside of the disk would continue in a straight line to exit that "fill in" area as well with the passage of time. In other words, any "filling in" would be only a temporary phenomenon. I'm certain someone with a little more expertise than I could calculate the duration that the "fill in" material would take to exit.starnut wrote: . . . The core's gravity would have caused the matter to curve inwards behind the core, the amount of deflection depending on the distance from the core. Even at the very high speed of the blast front, there would still be deflection of matter, and over the period of a thousand years, the deflected matter would have filled in the inside of the disk as it expanded away from the center. . .
