The search for radio emission from the exoplanetary systems 55 Cnc, Upsilon Andromedae, and Tau Boötis using LOFAR beam-formed observations

Résumé

The detection of planetary auroral radio emission is the only method to unambiguously observe exoplanetary magnetic fields. Over the past few decades, a number of observational campaigns searching for exoplanetary radio emission have been performed and none have been successful. Observations of an exoplanet's magnetic field would allow constraints on planetary properties difficult to study such as their interior structure (composition and thermal state), atmospheric escape, the physics of star-planet interactions, and even habitability. In this study, we present the detection of the most conclusive exoplanetary radio signal to date from the hot Jupiter Tau Bootis. If confirmed, this detection would be the birth of a brand new field of observational exoplanet research.
