ACCRETION OF ROCKY PLANETS BY HOT JUPITERS [PDF]

open access: yesThe Astrophysical Journal, 2011
The observed population of Hot Jupiters displays a stunning variety of physical properties, including a wide range of densities and core sizes for a given planetary mass. Motivated by the observational sample, this paper studies the accretion of rocky planets by Hot Jupiters, after the Jovian planets have finished their principal migration epoch and ...

Separating Super-puffs versus Hot Jupiters among Young Puffy Planets [PDF]

open access: yesThe Astrophysical Journal
Discoveries of close-in young puffy ( R _p ≳ 6 R _⊕ ) planets raise the question of whether they are bona fide hot Jupiters or puffed-up Neptunes, potentially placing constraints on the formation location and timescale of hot Jupiters.

TESS giants transiting giants V - Two hot Jupiters orbiting red-giant hosts [PDF]

open access: yes, 2023
: In this work we present the discovery and confirmation of two hot Jupiters orbiting red-giant stars, TOI-4377 b and TOI-4551 b, observed by TESS in the southern ecliptic hemisphere and later followed-up with radial-velocity (RV ...

Are hot Neptunes partially evaporated hot Jupiters? [PDF]

open access: yes, 2011
The detection of short period planets (hot Jupiters and their lower mass counterparts, hot Neptunes and super-Earths) still defies the models of planet formation and evolution. Several possibilities have been proposed to explain the nature and formation process of the lower mass population, including in situ formation, disk migration, planet-planet ...

Patchy Nightside Clouds on Ultra-hot Jupiters: General Circulation Model Simulations with Radiatively Active Cloud Tracers [PDF]

open access: yes, 2022
The atmospheres of ultra-hot Jupiters have been characterized in detail through recent phase curve and low- and high-resolution emission and transmission spectroscopic observations.

Colour–colour and colour–magnitude diagrams for hot Jupiters [PDF]

open access: yes, 2020
We use ground-based and space-based eclipse measurements for the near-infrared (IR) bands (JHKs) and Spitzer 3.6- and 4.5-μm bands to construct colour–colour and colour–magnitude diagrams for hot Jupiters.

Evidence of three mechanisms explaining the radius anomaly of hot Jupiters [PDF]

open access: yes, 2021
Context. The anomalously large radii of hot Jupiters are still not fully understood, and all of the proposed explanations are based on the idea that these close-in giant planets possess hot interiors. Most of the mechanisms proposed have been tested on a

CIRCULATION AND DISSIPATION ON HOT JUPITERS [PDF]

open access: yesThe Astrophysical Journal, 2010
Many global circulation models predict supersonic zonal winds and large vertical shears in the atmospheres of short-period jovian exoplanets. Using linear analysis and nonlinear local simulations, we investigate hydrodynamic dissipation mechanisms to balance the thermal acceleration of these winds.
