Merge this article?

Don't we have anyplace we can merge this article. This article seems to be so litle to write.--Freewayguy Call? Fish 21:44, 24 July 2008 (UTC)Reply

It should really be considered a child article of Stellar classification. I think what the article should cover is the spectral characteristics of class K stars. I.e. the prominent absorption lines. It could contrast the spectra of K-type giants versus dwarfs. Also it could discuss the degree of convection and surface activity.—RJH (talk) 18:08, 13 September 2009 (UTC)Reply

Mass range

edit

The given mass range is dubious in the light of such examples as the exoplanet host star XO-2, with solar mass but a K0V spectral type. Probably this is due to metallicity effects, but then the mass range should be qualified with the metallicity it is appropriate for. Icalanise (talk) 22:07, 5 June 2010 (UTC)Reply

The mass range is still disputed, but until there is a better source, we're stuck with what is there. Metallicity effects should be discussed briefly in the body of the article (with a reference), and then the lead can have a suitable summary. Lithopsian (talk) 12:42, 28 August 2022 (UTC)Reply

Rename this page

edit

This page could have a better name, it could be "orange dwarf".--Io Herodotus (talk) 10:16, 2 July 2014 (UTC)Reply

Of all the main-sequence star types O,B,A,F,G,K,M only the M-dwarfs seem to be more frequently referred to by their colloquial name "red dwarfs". So I think it should not be renamed per WP:COMMONNAME. Astredita (talk) 23:54, 2 July 2014 (UTC)Reply

Sigma Draconis

edit

Sigma Draconis is listed here as a spectral type K0 V ON its own Wikipedia page the same star is listed as a G9 V and has two references. — Preceding unsigned comment added by 2601:58B:4103:6D60:4BC:9BD7:FDD:2914 (talk) 15:00, 8 July 2020 (UTC)Reply

I changed σ Draconis to have K0 in the starbox since this is a standard star on the MK system. Lithopsian (talk) 15:49, 8 July 2020 (UTC)Reply

Orange dwarf

edit

The term orange dwarf has become quite common in Wikipedia. However, its use in other publications is relatively rare. The term red dwarf is far more commonly used, even for K-type main sequence star, and particularly for late-K dwarfs. It is possible to find reliable sources using the term orange dwarf, but far easier to find sources for the use of red dwarf applied to K stars. I will hunt down some sources and modify the article.
