Discovering and Characterising Exoplanets and Ultracool Dwarfs with the Square Kilometre Array
Robert D. Kavanagh, Juan B. Climent, Philippe Zarka +16
The paper discusses how the Square Kilometre Array will enable the detection of low‑frequency radio emission from giant exoplanets and thousands of ultracool dwarfs, allowing chara…
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…
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…
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…
Searching for planet-induced radio signal from the young close-in planet host star HIP 67522
Ekaterina Ilin, Sanne Bloot, Joseph R. Callingham +1
HIP 67522 is a 17 Myr old 1.2 dwarf, and the only such young star known to host two close-in gas giant planets. The inner planet likely orbits close enough to its host to…
Gaia-4b and 5b: Radial Velocity Confirmation of Gaia Astrometric Orbital Solutions Reveal a Massive Planet and a Brown Dwarf Orbiting Low-mass Stars
Gudmundur Stefansson, Suvrath Mahadevan, Joshua Winn +31
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity data are needed for definitive confirmation…
