Talk:Ultra-cool dwarf

This article has been mentioned by a media organization:

John Timmer (December 1, 2023). "Neptune-sized exoplanet is too big for its host star". Ars Technica. Archived from the original on December 2, 2023. Retrieved December 2, 2023. (Yes, ultracool dwarfs are enough of a thing to merit their own Wikipedia entry.)

Time for an update![edit]

In the wake of NASA's announcement of the finding of 4 new planets around TRAPPIST-1, this page is going to see a lot of hits. I'm in touch with someone at SETI who will be able to help out with finding material to expand this article. Also my French is good enough to deal with it. I'm going to translate and copy over the material from the existing French page at https://fr.wikipedia.org/wiki/Naine_ultra-froide tomorrow. If anyone wants to collaborate or help out, let me know.

Year of coining[edit]

It looks to me that the term was actually coined in 1995, see this paper. --192.35.35.35 (talk) 19:43, 22 February 2017 (UTC)[reply]

Thanks. That's just one of the issues, including a link to a David Kirkpatrick page which actually doesn't exist (wrong one), no citations, etc etc. I'm compiling more information and will have time to address this all properly tomorrow. Also my SETI contact is going to see what she can come up with, so hopefully we can make a fairly comprehensive page. Cadar (talk) 20:58, 22 February 2017 (UTC)[reply]

surface water?[edit]

" and one with likely surface water " - where is the RS that states this? It's certainly not within the ESO pdf/paper referenced. Wherever THAT came from, by the way? The link should be to the hosting site, not the paper itself. 104.169.17.29 (talk) 23:41, 23 February 2017 (UTC)[reply]

Is the surface water you mention from the new TRAPPIST-1 discoveries? The inference is currently because some of the newly found planets are within the so-called "habitable zone" - a misnomer if ever there was one - but at this stage we have absolutely no idea of the surface conditions of any of the planets, and further, any planets in such close orbits are usually tidally locked to their parent star. Surface water is a bit of a stretch, but time will tell. Cadar (talk) 06:03, 24 February 2017 (UTC)[reply]

further updates pending[edit]

I've managed to find a couple of papers, but they're actually too specific to TRAPPIST-1 and don't really supply any new information about ultra cool dwarf stars. The search goes on. When I have new information, I'll add it.
