How do we explain hot Jupiters?
A hot Jupiter is a planet that's around the mass and size of Jupiter. But instead of being far away from the sun like our own Jupiter, it's very close to its star. The exact definitions vary, but for the purpose of the Annual Review article we say it's a Jupiter within about 0.1 astronomical units of its star.
Where are hot Jupiters found?
Most hot Jupiters are found when they transit – cross in front of – their stars, causing a dip in the stars' light. As Mansfield said: These systems, these stars and their hot Jupiters, are too far away to resolve the individual star and its planet.
Where did hot Jupiters probably form?
These “hot-Jupiters” probably formed in the outer, cooler regions of their protoplanetary disks, and migrated inward to ∼0.1 AU. Since these giant planets must have migrated through their inner systems at an early time, it is uncertain whether they could have formed or retained terrestrial planets.
What is the favored explanation of the origin of this hot Jupiter type of planet?
What's the best explanation for the location of hot Jupiters? –They formed closer to their stars than Jupiter did.
How do we think hot Jupiters formed quizlet?
How do we think hot Jupiters formed? Hot Jupiters formed beyond the frost line, as in our solar system, and migrated inward due to interaction with the solar nebula.
What is a hot Jupiter quizlet?
What is a so-called "hot Jupiter"? a planet with a mass similar to Jupiter but very close to the central star and therefore hot. You just studied 38 terms!
What is the best explanation for the location of hot Jupiters quizlet?
What's the best explanation for the location of hot Jupiters? They formed farther out like Jupiter but then migrated inward.
How were hot Jupiters formed?
In the migration hypothesis, a hot Jupiter forms beyond the frost line, from rock, ice, and gases via the core accretion method of planetary formation. The planet then migrates inwards to the star where it eventually forms a stable orbit. The planet may have migrated inward smoothly via type II orbital migration.

What is the most likely explanation for the presence of hot Jupiters in extrasolar planetary systems?
Today, the leading hypothesis for the existence of hot Jupiters is that they formed in their outer solar systems and then migrated inward.
