this is basically a place to post some interesting wikipedia articles you may find and discuss them. I'll start with a very interesting piece I came across:
A Chthonian planet (pronounced /ˈkθoʊniən/, sometimes misspelled Cthonian), is a hypothetical class of celestial objects resulting from the stripping away of a gas giant's hydrogen and helium atmosphere and outer layers. Such atmospheric stripping is a likely result of proximity to a star. The remaining rocky or metallic core would resemble a terrestrial planet in many respects.[1]
HD 209458b (Osiris) is an example of a planet that is in the process of having its atmosphere stripped away, though it is not itself a Chthonian planet nor is it expected to become one in the near future.
COROT-7b may be the first Chthonian planet discovered.[2]
Chthonia χθων means "of the Earth" in Greek. The term was coined by Hébrard et al., since the term Chthonian generally refer to Greek deities from hot infernal underground.
