Talk:List of smallest known stars

Very wrong sizes

edit

Most red dwarf stars cited have tens or hundreds times the radius of Jupiter. For example, the article claims that Kapteyn's Star has 303.1 times the radius of Jupiter. Since Jupiter has about 1/10 the Sun's radius, this would make it 30 times larger than the Sun.

It is clearly for me that all or almost all of the data show in this article is grossly incorrect. I suspect that those numbers are the star volumes measured by Jupiter's volumes. Not the radius measured by Jupiter's radius. 177.158.73.159 (talk) 11:13, 23 January 2016 (UTC)Reply

What are the odds that I would come here on the same day to comment exactly that! Either incorrect conversions or incorrect labelling.193.40.5.245 (talk) 12:28, 23 January 2016 (UTC)Reply

5 years late, but the sizes for CXOU J085201.4-461753, PSR B0943+10, and CXO J232327.9+584842 seem impossibly small, with CXOU J085201.4-461753 being listed at only 1.2 kilometers in radius. That should be a black hole. Inky Bendy (talk) 19:46, 1 December 2021 (UTC)Reply

I agree, CXOU J085201.4-461753 to have a size of 1.2 kilometers in radius, it would have to have a mass less than 0.4 M, according to https://arxiv.org/abs/astro-ph/0207602 a radius of 10 kilometers based on a temperature of 90 eV (1,044,450 K) which is probably more accurate.

Article on the blackhole says the size claim has been withdrawn.©Geni (talk) 07:21, 16 July 2017 (UTC)Reply

SSSPM J2356-3426

Can someone point to where the mentioned radius appears in the paper? Have trouble finding it. 82.44.230.254 (talk) 01:05, 10 December 2023 (UTC)Reply

I can't find that one size, but I found a size of SSSPM J2356-3426 that is 10% the size of the Sun. Orangefanta120 (talk) 19:50, 10 November 2024 (UTC)Reply

WISE 0855-0714 sub brown dwarf not a star

edit

WISE 0855-0714 is a sub brown dwarf, not a star (even a brown dwarf). 174.103.211.175 (talk) 23:25, 4 July 2024 (UTC)Reply
