Talk:Iota Horologii b

message: The following claims need backing up:
*The concept of "sulfur giants". A google search basically turns up references to the popular site Extrasolar Visions, and this paper suggests that sulfur forms compounds other than sulfuric acid on such planets. This suggests that sulfur giants are a concept invented by the author of the Extrasolar Visions site.
*Even if sulfur giants exist, a reference to the yellow/green color is needed.
*The term "Horologid planet" does not seem to be in use anywhere.
*The temperature and radius values appear to be taken from Extrasolar Visions which uses simple calculations and models to get these parameters, which may be inaccurate (see here). Presenting them in the infobox implies these parameters have been measured, which is NOT the case.
**It is slightly ridiculous to assume we can give the radius to 4 significant figures when we only have a lower limit on the mass, and not a particularly good one at that (see the error value!). Chaos syndrome 10:09, 28 June 2006 (UTC)

replies: text: I realise that Extrasolar Visions states the planet is a sulfur giant, but it does not provide any references for the concept at all, and it doesn't seem to exist outside Extrasolar Visions apart from sites mirroring EV. I've also linked a paper in this talk page which implies that gas giants won't form layers of sulfuric acid clouds at any temperature. I still feel this issue needs outside attention (i.e. someone other than you or myself), so I'm replacing the notice for now. Chaos syndrome 13:54, 23 June 2006 (UTC)

message: Can anyone explain what is meant by 'insolation similar to Venus'?  I followed the link to insolation, which was fine as an explanation of insolation, but it doesn't shed any light on why the insolation is similar to Venus.  Do they mean it receives the same energy as Venus?  Do they mean it seems to reflect similar energy?  Venus is both very reflective and super-insulated - what is the insight given by the comparison.  Mostly just curious.  Stevebritgimp 20:05, 25 April 2007 (UTC)

message: on the planetbox says that the planet's mass is 2.24 MJ, and on the article says 1.94 MJ as minimum. one of this most be the Mcos(i) of the planet, but the other cames from...?

message: Sulfurous cloud jovians is a term invented by the now-defunct website Extrasolar Visions based on analogy with Venus: as a term it does not exist in the scientific literature, nor is the predicted chemistry of sulfur in a gas giant predicted to result in such a situation. The Venus analogy used by Extrasolar Visions is a bad one: Venus is a terrestrial planet, with oxygen-dominated chemistry (i.e. oxygen-rich compounds), gas giants have hydrogen-dominated chemistry. It is thus completely incorrect to make the analogy from the global sulfuric acid clouds in the carbon-dioxide rich atmosphere of Venus to sulfuric acid clouds in a hydrogen-rich gas giant. 86.171.72.213 (talk) 16:31, 22 August 2008 (UTC)
