Evidence of star–planet interactions in the form of planet-modulated chromospheric emission has been noted for a number of hot Jupiters. Magnetic star–planet interactions involve the release of energy stored in the stellar and planetary magnetic fields. These signals thus offer indirect detections of exoplanetary magnetic fields. Here, we report the derivation of the magnetic field strengths of four hot Jupiter systems, using the power observed in calcium ii K emission modulated by magnetic… 
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
Detecting Magnetic Fields in Exoplanets with Spectropolarimetry of the Helium Line at 1083 nm
The magnetic fields of the solar system planets provide valuable insights into the planets' interiors and can have dramatic consequences for the evolution of their atmospheres and interaction with
A scaling relationship for non-thermal radio emission from ordered magnetospheres: from the top of the main sequence to planets
In this paper, we present the analysis of incoherent non-thermal radio emission from a sample of hot magnetic stars, ranging from early-B to early-A spectral type. Spanning a wide range of stellar
Observational Features of Exoplanetary Synchrotron Radio Bursts
Magnetic fields of exoplanets are important in shielding the planets from cosmic rays and interplanetary plasma. Due to the interaction with the electrons from their host stars, the exoplanetary
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
Radio observations of HD 80606 near planetary periastron
Context. All the giant planets in the Solar System generate radio emission via electron cyclotron maser instability, giving rise most notably to Jupiter’s decametric emissions. An interaction with
Stellar impact on disequilibrium chemistry and observed spectra of hot Jupiter atmospheres
In this work we study the effect of disequilibrium processes on mixing ratio profiles of neutral species and on the simulated spectra of a hot Jupiter exoplanet that orbits stars of different
Radio Observations of HD80606 Near Planetary Periastron: II. LOFAR Low Band Antenna Observations at 30-78 MHz
All of the giant planets in the solar system generate radio emission via the electron cyclotron maser instability, most notably giving rise to Jupiter's decametric emissions. An interaction with the
A measurement of the wind speed on a brown dwarf
TLDR
Radio and infrared monitoring of a nearby brown dwarf show that its atmosphere has strong winds in an east-west direction, and this technique can be applied to brown dwarfs and/or directly imaged exoplanets if periods can be determined for both the infrared and radio emissions.

Energy flux determines magnetic field strength of planets and stars
TLDR
This work reports an extension of a scaling law derived from geodynamo models to rapidly rotating stars that have strong density stratification, and predicts that the field strengths of rapidly rotating brown dwarfs and massive extrasolar planets are high enough to make them observable.
Estimating the magnetic field strength in hot Jupiters
A large fraction of known Jupiter like exoplanets are inflated as compared to Jupiter. These "hot" Jupiters orbit close to their parent star and are bombarded with intense starlight. Many theories
Stellar coronal magnetic fields and star-planet interaction
Context. Evidence of magnetic interaction between late-type stars and close-in giant planets is provided by the observations of stellar hot spots rotating synchronously with the planets and showing
