Radio emission from star-planet interactions
H. K. Vedantham, A. Strugarek, C. K. Louis +12
Stars interact with their exoplanets though gravity, radiation, plasma and magnetic fields. Stellar plasma and magnetic fields impose electrodynamic effects on exoplanet atmosphere…
Spectroscopic Characterization of LOFAR Radio-emitting M dwarfs
E. Koo, G. Stefansson, R. D. Kavanagh +20
Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such em…
Close-in planet induces flares on its host star
Ekaterina Ilin, Harish K. Vedantham, Katja Poppenhäger +4
In the past decade, hundreds of exoplanets have been discovered in extremely short orbits below 10 days. Unlike in the Solar System, planets in these systems orbit their host stars…
Deep radio interferometric search for decametre radio emission from the exoplanet Tau Boötis b
C. M. Cordun, H. K. Vedantham, M. A. Brentjens +1
Detection of electron cyclotron maser (ECM) emission from exoplanets in the 10-40 MHz radio band is likely the only way to measure an exoplanet's magnetic field directly. However,…
uGMRT Survey of EXoplanets Around M-dwarfs (GS-EXAM): Radio observations of GJ 1151
Mayank Narang, Manoj Puravankara, H. K. Vedantham +9
Coherent radio emission with properties similar to planetary auroral signals has been reported from GJ 1151, a quiescent, slow-rotating mid-M star, by the LOFAR Two-metre (120-170…
Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather
J. R. Callingham, B. J. S. Pope, R. D. Kavanagh +22
Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain…
