Images[edit]

Consider this image:

It was deleted in favor of the existing image of the debris ring around Formalhaut. Does anyone want to keep this image or should we let it go? Stephen Charles Thompson (talk) 04:01, 17 November 2008 (UTC)[reply]

My preference is to see this article get expanded, with the images applied where appropriate.—RJH (talk) 19:28, 17 November 2008 (UTC)[reply]

In the linked articles of stars with debris disks, I have found only 2 actual images: Formalhaut and AU Microscopii. Is this all we have or can we get more? Stephen Charles Thompson (talk) 07:17, 25 November 2008 (UTC)[reply]

On Google you should be able to find images for the debris disks around Beta Pictoris, Epsilon Eridani, HD 107146, HD 53143 and so forth. But I'm not sure that they are suitably licensed for use in wikipedia.—RJH (talk) 17:10, 25 November 2008 (UTC)[reply]

We have sent so many probes into deep space, can none of them show us our own debris disk? Stephen Charles Thompson (talk) 07:19, 25 November 2008 (UTC)[reply]

If you mean the asteroid belt, then it has less matter and is closer to the central star (Sun) than most of these disks. So ours would be difficult to detect from neighboring systems using comparable equipment. But we do have images of the zodiacal light.[1]—RJH (talk) 16:32, 25 November 2008 (UTC)[reply]

Importance[edit]

I know from personal knowledge that a debris disk is ESSENTIAL to the formation of planets. Can someone please help me justify the HIGH importance of this topic by expanding the role that a debris disk plays in the formation/evolution of a solar system? The topic is played out in (every) article about a star with a debris disk. There should be a central discussion on this theme. Stephen Charles Thompson (talk) 07:24, 25 November 2008 (UTC)[reply]

The High importance in this article is based upon the categorization at Wikipedia:WikiProject_Astronomy/Importance_ratings#Objects. That is based upon the fundamental nature of this object category (as a subset of the more general circumstellar disks), rather than any particular role it may or may not have in planet formation. The protoplanetary disk article covers planet formation from the collapse of a solar nebula.—RJH (talk) 16:07, 25 November 2008 (UTC)[reply]

Debris disks do not play much of a role in the formation of planets. The disks are formed of the debris left over after the planets have formed. The dust observed is not primordial since it has lifetimes much less than the age of the system and is produced recently through collisions of larger objects.

Merge with circumstellar disk?[edit]

Both articles are talking about the same thing. I suggest we merge them. AnyOldBiscuit (talk) 18:19, 25 September 2018 (UTC)[reply]
