astro-ph.SR2025

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…

Revealing the accelerating wind in the inner region of the colliding-wind binary WR 112

John D. Monnier, Yinuo Han, Michael F. Corcoran +17

Colliding winds in massive binaries generate X-ray-bright shocks, synchrotron radio emission, and sometimes even dusty "pinwheel" spirals. We report the first X-ray detections of t…

Radio Burst Phenomenology of AD Leonis and Associated Signatures of Propagation Effects

Jiale Zhang, Harish K. Vedantham, Joseph R. Callingham +1

We present the high-resolution radio dynamic spectra of AD Leonis (AD Leo) between 1.0 and 1.5 GHz taken by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) on Dec.…

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…
