3 planets it's been found around HD20794 (82 Eridani): The HARPS search for Earth-like planets in the habitable zone: I -- Very low-mass planets around HD20794, HD85512 and HD192310 http://arxiv.org/abs/1108.3447 — Preceding unsigned comment added by 220.127.116.11 (talk) 01:00, 18 August 2011 (UTC)
Has luminosity value been reported in a journal or other reliable published source? If so, use the published value and cite the publication. I don't think it's necessarily good practice to add original research by doing calculations and entering them into WP articles. AstroCog (talk) 16:52, 2 November 2011 (UTC)
I was going to say...
where L is luminosity, R is radius and Teff
is not a reference, even if the formula is known, the unpublished results makes it original research. 18.104.22.168 (talk) 22:50, 10 January 2012 (UTC)
Let me be clearer, the L=0.62 is all that is necessary even if the figure comes from a paper that illustrates the calculation with a formula. 22.214.171.124 (talk) 22:56, 10 January 2012 (UTC)
- I think it is preferred practice to use a value from a published source. If that is not available and there's a consensus to use a calculation (per WP:CALC), then I'd like to recommend putting in a cite for the formula and show the calculation. That way we know what numbers you used, and we can change the result when the estimates are revised. For example:
Are some planets in the habitable zone?
The article never makes this clear. One scientist speculating about a 5% chance does not represent scientific consensus, nor is it very clear. Is it within the generally theorized habitable zone or not? If not, is it in the theorized border range of a habitable planet? If so what are the specifics?
