Summary[edit]
| Description |
English: For the very hottest gas giants, with temperatures above 1400 K (2100°F, 1100 °C) or cooler planets with lower gravity than Jupiter, the silicate and iron cloud decks are predicted to lie high up in the atmosphere. These planets are class V and their predicted Bond albedo around a Sun-like star is 0.55, due to reflection by the cloud decks. At such temperatures, agas giant may glow red from thermal radiation but the reflected light generally overwhelms thermal radiation. For stars of visual apparent magnitude under 4.50, such planets are theoretically visible to our instruments. Examples of such planets might include 51 Pegasi b and Upsilon Andromedae b. HAT-P-11b and those other extrasolar gas giants found by the Kepler telescope might be possible class V planets, such as Kepler-7b, HAT-P-7b, or Kepler-13b. |
