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…
Direct radio discovery of a cold brown dwarf
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +9
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 rad…
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11
Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…
No Massive Companion to the Coherent Radio-Emitting M Dwarf GJ 1151
Benjamin J. S. Pope, Megan Bedell, Joseph R. Callingham +4
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-…
Exoplanet Transits with Next-Generation Radio Telescopes
Benjamin J. S. Pope, Paul Withers, Joseph R. Callingham +1
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), w…
