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…
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…
Peculiar radioX-ray relationship in active stars
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +5
The empirical relationship between the non-thermal 5GHz radio luminosity and the soft X-ray luminosity of active stellar coronae, canonically called the Güdel-Benz relationship (Gü…
The population of M dwarfs observed at low radio frequencies
J. R. Callingham, H. K. Vedantham, T. W. Shimwell +12
Coherent low-frequency ( MHz) radio emission from stars encodes the conditions of the outer corona, mass-ejection events, and space weather. Previous low-frequency se…
Detection of coherent low-frequency radio bursts from weak-line TTauri stars
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +7
In recent years, thanks to new facilities such as LOFAR capable of sensitive observations, much work has been done on the detection of stellar radio emission at low frequencies. Su…
Low-frequency monitoring of flare star binary CR Draconis: Long-term electron-cyclotron maser emission
J. R. Callingham, B. J. S. Pope, A. D. Feinstein +12
Recently detected coherent low-frequency radio emission from M dwarf systems shares phenomenological similarities with emission produced by magnetospheric processes from the gas gi…
