:No, it is only theorised that the dark bands indicate planetesimal consolidation. We have no way of knowing for certain yet. <span style="white-space:nowrap; text-shadow:gray 5px 3px 1px;">— ] <small>(] ] ])</small></span> 02:21, 11 November 2014 (UTC)

Age of HL Tauri system

The newest article seems to state that the system is approximately 1,000,000 years old while the older reference in the synopsis states only 100,000 years old. Is there a need to update the synopsis with the new information perhaps? — Preceding unsigned comment added by SBHans13 (talk • contribs) 20:58, 10 November 2014 (UTC)

Until a paper can be produced showing that data, I'd prefer to use the refereed material over a press release. Also, the ESO release seems to be saying that the system is a maximum of a million years old, not that it is a million years. — Huntster (t @ c) 21:26, 10 November 2014 (UTC)

Planets around HL Tauri

Is it true that although the exact nature and number of planets about HL Tauri is not known, it is known that HL Tauri has planets? --Artman40 (talk) 23:30, 10 November 2014 (UTC)

No, it is only theorised that the dark bands indicate planetesimal consolidation. We have no way of knowing for certain yet. — Huntster (t @ c) 02:21, 11 November 2014 (UTC)
