Talk:HD 181433

Correction needed
This article appears incorrect. HD 181433 contains 2 planets and is not the star in the Doradus and Pictor constellation.

 * Then it will be corrected, note the article did not mention it was in these constellations but near them, and that is verified, I have admitted the mistake on three planets and that has been corrected. Argentium (talk) 17:20, 16 June 2008 (UTC)

No data suggested 181433 b is Earth-like
There are two overall catagories for planet size, terrestrial and gas giant. The mear fact that this is not a gas giant does not implicate an Earth twin, so please refrain from trying to write any entries here about a new Earth, it is not funny. GabrielVelasquez (talk)

There is no Semi-Major axis data which would be need to even begin to guess at the temperature: so far it could be a ball(s) of magma or a ball(s) of ice. GabrielVelasquez (talk) 02:28, 27 June 2008 (UTC)

It is referenced, and I can find about 1000 more news articles saying about the super-earths. Argentium (talk) 16:36, 27 June 2008 (UTC) The size is not in question here (that's mathematics), do you get that? the beach resort with hot tubs is! - so save your frequent flyer miles for someplace else.

 * Listen, Super-genius: Super-Earth, New Earth... SUPER difference there.

I'm not acually interested in a disussion about this with you, I only added the section to show why this phrase was removed from the article "and alleged to have earthlike conditions" GabrielVelasquez (talk) 00:22, 2 July 2008 (UTC)

Category Listing
Why is it listed as a Subgiant? It's a dwarf with a radius smaller than the Sun. These category mistakes are causing a lot of confusion.--UltimateDarkloid (talk) 19:31, 18 September 2008 (UTC)

Interstellar dust?
Possibility of absorption by interstellar dust isn't accounted-for in the formula for absolute magnitude —Preceding unsigned comment added by 213.3.107.203 (talk) 13:17, 16 January 2009 (UTC)
 * Indeed, but the star is located relatively nearby so the effects should be fairly minor. Icalanise (talk) 21:58, 27 June 2009 (UTC)

Original Research Notes
Can someone explain why this is not considered Original Research, and if there is a list of these formulas on Wikipedia that one can refer to? 50.70.236.24 (talk) 04:13, 16 June 2018 (UTC)

$$f_p= \frac{( (0.38 \times 6.955 \times 10^8 )^2 ) \times (5.67051 \times 10^{-8}) \times (4902^4)} { ( ( 0.073 - ( 0.073 \times 0.16 ) ) \times 149597876600 )^2 }$$ Found this and consider it usable. 50.70.236.24 (talk) 14:58, 16 June 2018 (UTC)

$$R_s= ({L}/{(T)^2} )^(0.5) $$
