Multiple-Planet Scattering and the Origin of Hot Jupiters

open access: yes, 2011
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 star's rotation.

Multi-Component MHD Model of Hot Jupiter Envelopes

open access: yesUniverse, 2021
A numerical model description of a hot Jupiter extended envelope based on the approximation of multi-component magnetic hydrodynamics is presented. The main attention is focused on the problem of implementing the completed MHD stellar wind model.

On the Tidal Dissipation of Obliquity

open access: yes, 2013
We investigate tidal dissipation of obliquity in hot Jupiters. Assuming an initial random orientation of obliquity and parameters relevant to the observed population, the obliquity of hot Jupiters does not evolve to purely aligned systems.

ATMOSPHERIC HEAT REDISTRIBUTION ON HOT JUPITERS [PDF]

open access: yesThe Astrophysical Journal, 2013
Infrared lightcurves of transiting hot Jupiters present a trend in which the atmospheres of the hottest planets are less efficient at redistributing the stellar energy absorbed on their daysides---and thus have a larger day-night temperature contrast---than colder planets.

Hot Jupiters and the evolution of stellar angular momentum [PDF]

open access: yes, 2009
Giant planets orbiting main-sequence stars closer than 0.1 AU are called hot Jupiters. They interact with their stars affecting their angular momentum. Recent observations provide suggestive evidence of excess angular momentum in stars with hot Jupiters ...

TRANSITIONS IN THE CLOUD COMPOSITION OF HOT JUPITERS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT Over a large range of equilibrium temperatures, clouds shape the transmission spectrum of hot Jupiter atmospheres, yet their composition remains unknown. Recent observations show that the Kepler light curves of some hot Jupiters are asymmetric: for the hottest planets, the light curve peaks before secondary eclipse, whereas for ...

The formation and habitability of terrestrial planets in the presence of hot jupiters

open access: yes, 2004
`Hot jupiters,' giant planets with orbits very close to their parent stars, are thought to form farther away and migrate inward via interactions with a massive gas disk.

Superflares and “Hot-Jupiters” [PDF]

open access: yesSymposium - International Astronomical Union, 2004
Schaefer, King & Deliyannis (2000) reported the discovery of powerful stellar flares on single, solar-type stars. The outbursts on these F8-G8 stars were 102–107 times more powerful than the largest solar flares. The observed properties are similar to the magnetic reconnection driven events of RS CVn binaries.

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

open access: yesAdvanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Unified Formation Channel of Hot and Warm Jupiters via Planet–Planet Scattering

open access: yesThe Astrophysical Journal Letters
Recent observations show distinct orbital architectures for hot and warm Jupiters: hot Jupiters span a wide range of stellar obliquities and tend to host distant companions without close-by companions, whereas warm Jupiters are often aligned and ...
