The timescale for giant planet formation : constraints from the rotational evolution of exoplanet host stars

TL;DR

This paper investigates the timescale for giant planet formation by analyzing how the rotation rates of stars hosting exoplanets evolve, providing new constraints on when planets form in circumstellar disks.

Contribution

It introduces a novel method of constraining planet formation timescales through the study of stellar rotational evolution.

Findings

Rotational evolution of exoplanet host stars constrains planet formation timescales.

New limits on the duration of planet formation in circumstellar disks.

Implications for planetary formation models based on stellar rotation data.

Abstract

The timescale over which planets may form in the circumstellar disks of young stars is one of the main issues of current planetary formation models. We present here new constraints on planet formation timescales derived from the rotational evolution of exoplanet host stars.
