Structure and evolution of super-Earth to super-Jupiter exoplanets - I. Heavy element enrichment in the interior

TL;DR: In this paper, the authors examine the uncertainties in current planetary models and quantify their impact on the planet cooling histories and massradius relationships, including the differences between the various equations of state used to characterize the heavy material thermodynamic properties, the distribution of heavy elements within planetary interiors, their chemical composition, and their thermal contribution to the planet evolution.
Journal ArticleDOI

Episodic Accretion at Early Stages of Evolution of Low-Mass Stars and Brown Dwarfs: A Solution for the Observed Luminosity Spread in H-R Diagrams?

TL;DR: In this paper, the authors present evolutionary models for young low-mass stars and brown dwarfs taking into account episodic phases of accretion at early stages of the evolution, a scenario supported by recent large surveys of embedded protostars.

Episodic accretion at early stages of evolution of low mass stars and brown dwarfs: a solution for the observed luminosity spread in HR diagrams?

TL;DR: In this paper, the authors present evolutionary models for young low mass stars and brown dwarfs taking into account episodic phases of accretion at early stages of the evolution, a scenario supported by recent large surveys of embedded protostars.
Journal ArticleDOI

Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity

TL;DR: In this paper, the authors present the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet, and revisit the viability of the tidal heating hypothesis to explain the anomalously large radius of transiting giant planets.
Journal ArticleDOI

The mass-dependence of angular momentum evolution in sun-like stars

TL;DR: In this article, a physically motivated scaling for the dependence of the stellar wind torque on the Rossby number was derived, which explains why the lowest mass stars are observed to maintain rapid rotation for much longer than solar-mass stars.
