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…

Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J050827292101444
Simranpreet Kaur, Daniele Viganò, Víctor J. S. Béjar +18
Scallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are sta…
