Exploration of the brown dwarf regime around solar-like stars by CoRoT

TL;DR

This study utilizes CoRoT photometric data and ground-based radial velocity measurements to identify and analyze three transiting brown dwarfs around solar-like stars, estimating their occurrence rate.

Contribution

First detection and characterization of transiting brown dwarfs around solar-like stars using CoRoT data, providing new insights into their occurrence rate.

Findings

Detected three transiting brown dwarfs around F and G stars.

Estimated brown dwarf occurrence rate of 0.20% around solar-like stars.

Results are consistent with Kepler data findings.

Abstract

Aims. A summary of the CoRoT brown dwarf investigations are presented. Methods. Transiting brown dwarfs around solar like stars were studied by using the photometric time-series of CoRoT, and ground based radial velocity measurements. Results. CoRoT detected three transiting brown dwarfs around F and G dwarf stars. The occurence rate of brown dwarfs was found to be 0.20 +/- 0.15% around solar-like stars which is compatible with the value obtained by Kepler-data.
