The following paper conflicts with the masses that were apparently copied from the SolStation site:
- Heintz, W. D., "The Substellar Masses of WOLF:424", ASTRONOMY AND ASTROPHYS. V.217, NO.1/2 JUN(II), P. 145, 1989.
So it is unclear which is correct. — RJH 20:54, 23 August 2005 (UTC)
- Okay, this was addressed in a later paper which I have now cited. — RJH 21:08, 23 August 2005 (UTC)
I also stumbled over the inconsistent mass data. List_of_least_massive_stars has the lower numbers. To make the inconsistency more obvious to readers I reconverted the (lower) jupiter figures back to solar masses. Maybe someone should write some words about the discrepancy.

- There's another: "approximately 0.14 solar masses (63 Jupiters (0.060 solar masses))...approximately 0.13 solar masses (52 Jupiters (0.050 solar masses))" Now, I can't tell if that means Jupiter =.05-06 MSol, or if the Wolf dwarf(s) are, or what. And if it's Jupiter meant, why is there variability in the conversion? A clarification, with source, by somebody who understands this, is definitely required.

By reference to this page: http://kencroswell.com/BrownDwarfLithium.html one can see that, contrary to the previous consensus about those masses, Wulff Heintz in 1989 proposed the smaller numbers, which were subsequently disputed in 1991. Torres' numbers of 1999-- http://iopscience.iop.org/1538-3881/117/1/562?ejredirect=migration --may be considered the best at the present time. mrh
Masses 0.14 and 0.13 M☉ are what actually mentioned in the sources and these numbers are consistent with the spectral classes of the stars (see the article about the main sequence and referencies therein). So I think there was no contradiction, but just a simple error in converting solar mass into Jovian. GenyAncalagon (talk) 07:36, 27 May 2010 (UTC)
I could find nothing to corroborate this paragraph, so I removed it from the article:
- Due to its proximity and fast motion towards the Sun, Wolf 424 will brighten by more than 2% over the course of the 21st century. In approximately 7700 years, it will make its nearest approach at a distance of about 1 light year and passing through the distant reaches of the solar system, and will become the nearest stars.
