Hot Super Earths: Disrupted young jupiters?

  title={Hot Super Earths: Disrupted young jupiters?},
  author={S Nayakshin},
Recent Kepler observations revealed an abundance of ‘hot’ Earth-size to Neptune-size planets in the inner 0.02–0.2 au from their parent stars. We propose that at least some of these smaller planets are the remnants of massive giant planets that migrated inwards quicker than they could contract. We show that such disruptions occur if the young giant planet embryo is initially extended. The characteristic planet–star separation at which such ‘hot disruptions’ occur is R≈ 0.03–0.2 au. The…

An alternative origin for debris rings of planetesimals
Core accretion (CA), the most widely accepted scenario for planet formation, postulates existence of ∼ km-sized solid bodies, called planetesimals, arranged in a razor-thin disc in the earliest
Fu Ori outbursts and the planet-disc mass exchange
It is found that the mass-losing planet embedded in a realistic protoplanetary disc spawns an extremely rich set of variability patterns and in a subset of parameter space, there is a limit cycle behaviour caused by non-linear interaction between the planet mass-loss and the disc hydrogen ionization instability.
Radiative feedback from protoplanets in self-gravitating protoplanetary discs
It is well known that massive protoplanetary disc are gravitationally unstable beyond tens of AU from their parent star. The eventual fate of the self-gravitating gas clumps born in the disc is
Hydrogen-losing planets in transition discs around young protostars
We point out that protoplanets created in the framework of the Tidal Downsizing (TD) theory for planet formation play a very important role for the evolution of accretion discs hosting them. Since
Planet formation around M dwarfs via disc instability
Context. Around 30 per cent of the observed exoplanets that orbit M dwarf stars are gas giants that are more massive than Jupiter. These planets are prime candidates for formation by disc
Core-assisted gas capture instability: a new mode of giant planet formation by gravitationally unstable discs
Giant planet formation in the core accretion (CA) paradigm is predicated by the formation of a core, assembled by the coagulation of grains and later by planetesimals within a protoplanetary disc. In
Planetary companions around the metal-poor star HIP 11952
Aims. We carried out a radial-velocity survey to search for planets around metal-poor stars. In this paper we report the discovery of two planets around HIP 11952, a metal-poor star with [Fe/H]=−1.9

Differentiation of silicates and iron during formation of Mercury and high-density exoplanets
Recent MESSENGER observations confirmed that Mercury is dominated by a disproportion-ally large iron-rich core, and also showed a surprisingly high content of a moderately volatile element K on the


Formation of terrestrial planet cores inside giant planet embryos
Giant planet embryos are believed to be spawned by gravitational instability in massive extended (R ∼ 100 au) protostellar discs. In a recent paper, we have shown that dust can sediment inside the
Massive planets in FU Orionis discs: implications for thermal instability models
FU Orionis are young stellar objects undergoing episodes of enhanced luminosity, which are generally ascribed to a sudden increase of mass accretion rate in the surrounding protostellar disc. Models
We present models of giant planet migration in evolving protoplanetary disks. Our disks evolve subject to viscous transport of angular momentum and photoevaporation, while planets undergo Type II
On the Radii of Close-in Giant Planets
It is found that HD 209458b must be a hydrogen-rich gas giant and the large radius of a close-in gas giant is not due to the thermal expansion of its atmosphere but to the high residual entropy that remains throughout its bulk by dint of its early proximity to a luminous primary.
Orbital migration of the planetary companion of 51 Pegasi to its present location
THE recent discovery1 and confirmation2 of a possible planetary companion orbiting the solar-type star 51 Pegasi represent a breakthrough in the search for extrasolar planetary systems. Analysis of
Grain sedimentation inside giant planet embryos
It is argued that core formation through grain sedimentation inside the giant planet embryos may yield an unexplored route to form giant gas and giant ice planets.
Toward a Deterministic Model of Planetary Formation. V. Accumulation Near the Ice Line and Super-Earths
We address two outstanding issues in the sequential accretion scenario for gas giant planet formation, the retention of dust grains in the presence of gas drag and that of cores despite type I
On the Radii of Extrasolar Giant Planets
We have computed evolutionary models for extrasolar planets that range in mass from 0.1MJ to 3.0MJ and that range in equilibrium temperature from 113 to 2000 K. We present four sequences of models,
