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. 188.8.131.52 (talk) 11:13, 23 January 2016 (UTC)
What are the odds that I would come here on the same day to comment exactly that! Either incorrect conversions or incorrect labelling.184.108.40.206 (talk) 12:28, 23 January 2016 (UTC)
