Question

question 39
according to current understanding, how do we think \hot jupiters\ around other stars formed?
they formed as gas giants beyond the frost line & then migrated inwards.
they formed as gas giants close to the star in the same orbits theyre seen in today.
many planets were formed around the star but coalesced into a single planet close in.
they initially formed the same way & in the same area as super - earths do, but then gathered more hydrogen.

Explanation:

Hot Jupiters are thought to have formed as gas - giants beyond the frost line where it was cold enough for volatile compounds like water, ammonia, and methane to condense into solid ice grains, and then migrated inwards due to various dynamical processes such as gravitational interactions with other planets or the protoplanetary disk.

Answer:

They formed as gas giants beyond the frost line then migrated inwards.
