Hot Jupiters, giant extrasolar planets with orbital periods shorter than ∼10 days, have long been thought to form at large radial distances, only to subsequently experience long-range inward migration. Here, we offer the contrasting view that a substantial fraction of the hot Jupiter population formed in situ via the core-accretion process. We show that under conditions appropriate to the inner regions of protoplanetary disks, rapid gas accretion can be initiated by super-Earth-type planets… 
The Hot Jupiter Period–Mass Distribution as a Signature of in situ Formation
More than two decades after the widespread detection of Jovian-class planets on short-period orbits around other stars, their dynamical origins remain imperfectly understood. In the traditional
In situ formation of hot Jupiters with companion super-Earths
Observations have confirmed the existence of multiple-planet systems containing a hot Jupiter and smaller planetary companions. Examples include WASP-47, Kepler-730, and TOI-1130. We examine the
Atmospheric signatures of giant exoplanet formation by pebble accretion
Atmospheric chemical abundances of giant planets lead to important constraints on planetary formation and migration. Studies have shown that giant planets that migrate through the protoplanetary disk
On the Terminal Rotation Rates of Giant Planets
Within the general framework of the core-nucleated accretion theory of giant planet formation, the conglomeration of massive gaseous envelopes is facilitated by a transient period of rapid
Dynamical constraints on the origin of hot and warm Jupiters with close friends
Gas giants orbiting their host star within the ice line are thought to have migrated to their current locations from farther out. Here we consider the origin and dynamical evolution of observed
Exterior Companions to Hot Jupiters Orbiting Cool Stars Are Coplanar
The existence of hot Jupiters has challenged theories of planetary formation since the first extrasolar planets were detected. Giant planets are generally believed to form far from their host stars,
In situ scattering of warm Jupiters and implications for dynamical histories
Many warm Jupiters (WJs) have substantial eccentricities, which are linked to their formation and migration histories. This paper explores eccentricity excitation of WJs due to planet–planet
A Secular Resonant Origin for the Loneliness of Hot Jupiters
Despite decades of inquiry, the origin of giant planets residing within a few tenths of an astronomical unit from their host stars remains unclear. Traditionally, these objects are thought to have
Formation of hot Jupiters through secular chaos and dynamical tides
The population of giant planets on short-period orbits can potentially be explained by some flavours of high-eccentricity migration. In this paper, we investigate one such mechanism involving
Hot Jupiter and Ultra-cold Saturn Formation in Dense Star Clusters
The discovery of high incidence of hot Jupiters in dense clusters challenges the field-based hot Jupiter formation theory. In dense clusters, interactions between planetary systems and flyby stars

We propose that two of the most surprising results so far among exoplanet discoveries are related: the existences of both hot Jupiters and the high frequency of multi-planet systems with periods P ≲
MULTIPLE-PLANET SCATTERING AND THE ORIGIN OF HOT JUPITERS
Doppler and transit observations of exoplanets show a pile-up of Jupiter-size planets in orbits with a 3 day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent
Migration and the Formation of Systems of Hot Super-Earths and Neptunes
The existence of extrasolar planets with short orbital periods suggests that planetary migration induced by tidal interaction with the protoplanetary disk is important. Cores and terrestrial planets
Why are there so few hot Jupiters
We use numerical simulations to model the migration of massive planets at small radii and compare the results with the known properties of ’hot Jupiters’ (extrasolar planets with semi-major axes a
Jupiter’s decisive role in the inner Solar System’s early evolution
TLDR
Simulations show that a popular formation scenario for Jupiter and Saturn, in which Jupiter migrates inward from a > 5 astronomical units (AU) to a ≈ 1.5 AU before reversing direction, can explain the low overall mass of the Solar System’s terrestrial planets, as well as the absence of planets with a < 0.4 AU.
A low mass for Mars from Jupiter’s early gas-driven migration
TLDR
Simulation of the early Solar System shows how the inward migration of Jupiter to 1.5 au, and its subsequent outward migration, lead to a planetesimal disk truncated at 1’au; the terrestrial planets then form from this disk over the next 30–50 million years, with an Earth/Mars mass ratio consistent with observations.

Planet heating prevents inward migration of planetary cores
TLDR
It is reported that asymmetries in the temperature rise associated with accreting infalling material produce a force (which gives rise to an effect that is called ‘heating torque’) that counteracts inward migration and provides a channel for the formation of giant planets.
