We consider the magnetic interaction of exoplanets orbiting M dwarfs, calculating the expected Poynting flux carried upstream along Alfvén wings to the central star. A region of emission analogous to the Io footprint observed in Jupiter’s aurora is produced, and we calculate the radio flux density generated near the surface of the star via the electron-cyclotron maser instability. We apply the model to produce individual case studies for the TRAPPIST-1, Proxima Centauri, and dwarf NGTS-1…

Planet-induced radio emission from the coronae of M dwarfs: the case of Prox Cen and AU Mic
There have recently been detections of radio emission from low-mass stars, some of which are indicative of star-planet interactions. Motivated by these exciting new results, in this paper we present
Exoplanet Modulation of Stellar Coronal Radio Emission
This work indicates that radio signature of exoplanets might not be limited to low-frequency radio range, and finds that the intensity modulations are sensitive to the planetary magnetic field polarity for short-orbit planets, and to the stellar magnetic field strength for all cases.
Direct Radio Discovery of a Cold Brown Dwarf
Magnetospheric processes seen in gas giants such as aurorae and circularly polarized cyclotron maser radio emission have been detected from some brown dwarfs. However, previous radio observations
Exoplanet transits with next-generation radio telescopes
Nearly everything we know about extrasolar planets to date comes from optical astronomy. While exoplanetary aurorae are predicted to be bright at low radio frequencies (< 1 GHz), we consider the
Low-frequency monitoring of flare star binary CR Draconis: long-term electron-cyclotron maser emission
Recently detected coherent low-frequency radio emission from M dwarf systems shares phenomenological similarities with emission produced by magnetospheric processes from the gas giant planets of our
Unlocking the Origins of Ultracool Dwarf Radio Emission
Empirical trends in stellar X-ray and radio luminosities suggest that low-mass ultracool dwarfs (UCDs) should not produce significant radio emission. Defying these expectations, strong nonthermal
No Massive Companion to the Coherent Radio-emitting M Dwarf GJ 1151
The recent detection of circularly polarized, long-duration (>8 hr), low-frequency (∼150 MHz) radio emission from the M4.5 dwarf GJ 1151 has been interpreted as arising from a star–planet interaction
A Deep Radio Limit for the TRAPPIST-1 System
The first nearby very-low-mass star–planet-host discovered, TRAPPIST-1, presents not only a unique opportunity for studying a system of multiple terrestrial planets, but a means to probe
Coherent radio emission from a quiescent red dwarf indicative of star–planet interaction
Low-frequency ( ν  ≲ 150 MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission from the Sun has been used
Magnetohydrodynamic modelling of star–planet interaction and associated auroral radio emission
We present calculations of auroral radio powers of magnetized hot Jupiters orbiting Sun-like stars, computed using global magnetohydrodynamic (MHD) modelling of the magnetospheric and ionospheric


Magnetosphere–ionosphere coupling at Jupiter-like exoplanets with internal plasma sources: implications for detectability of auroral radio emissions
In this paper we provide the first consideration of magnetosphere–ionosphere coupling at Jupiter-like exoplanets with internal plasma sources such as volcanic moons. We estimate the radio power

Stellar wind–magnetosphere interaction at exoplanets: computations of auroral radio powers
We present calculations of the auroral radio powers expected from exoplanets with magnetospheres driven by an Earth-like magnetospheric interaction with the solar wind. Specifically, we compute the
The Detectability of Radio Auroral Emission from Proxima b
Magnetically active stars possess stellar winds whose interactions with planetary magnetic fields produce radio auroral emission. We examine the detectability of radio auroral emission from Proxima
Possible constraints on exoplanet magnetic field strengths from planet-star interaction
A small percentage of normal stars harbor giant planets that orbit within a few tenths of an astronomical unit. At such distances, the potential exists for significant tidal and magnetic field
Modeling the radio signature of the orbital parameters, rotation, and magnetic field of exoplanets
Context. Since the first extra-solar planet discovery in 1995, several hundreds of these planets have been discovered. Most are hot Jupiters, i.e. massive planets orbiting close to their star. These

The Radiometric Bode’s Law and Extrasolar Planets
We predict the radio flux densities of the extrasolar planets in the current census, making use of an empirical relation—the radiometric Bode's law—determined from the five "magnetic" planets in the
Auroral radio emissions at the outer planets: Observations and theories
We review both observational and theoretical aspects of the generation of auroral radio emissions at the outer planets, trying to organize the former in a coherent frame set by the latter. Important

We present an XMM-Newton X-ray observation of TRAPPIST-1, which is an ultracool dwarf star recently discovered to host three transiting and temperate Earth-sized planets. We find the star is a
