Hipparcos, Gaia, and RVs reveal that the radio emitting F star HD 220242 has an M dwarf companion, a likely source of the radio emission
Megan Delamer, Guðmundur Stefánsson, Suvrath Mahadevan +18
The detection of circularly polarized, low frequency radio emission offers the tantalizing possibility of the observation of interactions between stars and their possible substella…
Occurrence rate of stellar Type II radio bursts from a 100 star-year search for coronal mass ejections
David C. Konijn, Harish K. Vedantham, Cyril Tasse +8
Coronal mass ejections (CMEs) are major drivers of space weather in the Solar System, but their occurrence rate on other stars is unknown. A characteristic (deca-)metric radio burs…
A magnetic field study of two fast-rotating, radio bright M dwarfs. StKM 1-1262 and V374 Peg
S. Bellotti, P. I. Cristofari, J. R. Callingham +8
Radio observations at low frequencies are sensitive to the magnetic activity of stars and the plasma environment surrounding them. The accurate interpretation of the processes unde…
Radio Burst from a Stellar Coronal Mass Ejection
J. R. Callingham, C. Tasse, R. Keers +15
Coronal mass ejections (CMEs) are massive expulsions of magnetised plasma from a star, and are the largest contributors to space weather in the Solar System. CMEs are theorized to…
Unusual periodic modulation in the radio emission of the methane dwarf binary WISEP J101905.63+652954.2
Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1
Brown dwarfs display Jupiter-like auroral phenomena, such as rotationally modulated electron cyclotron maser radio emission. Radio observations of cyclotron maser emission can be u…
Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
Prospects for radio detection of stellar plasma beams
H. K. Vedantham
Violent solar eruptions are often accompanied by relativistic beams of charged particles. In the solar context, they are referred to as SPEs (Solar Particle Events) and are known t…
