Description
Radio activity in low-mass stars, including M dwarfs and substellar objects, has gained significant attention over the past decade. This interest has been driven in part by SKA pathfinder telescopes, particularly LOFAR, which have provided critical insights into the radio properties of stellar/sub-stellar objects at meter wavelengths. The upcoming Square Kilometre Array (SKA) is poised to revolutionize our understanding of magnetic activity in these objects by offering unprecedented sensitivity and frequency coverage, enabling the detection of weak, persistent emission from a broader range of substellar sources. Meanwhile, the James Webb Space Telescope (JWST) has recently identified numerous L, T, and Y dwarfs, providing an unprecedented window into their atmospheric properties. Together, SKA and JWST will offer a complementary view of ultracool dwarfs, probing both their magnetic fields and atmospheric structures.
We present the detection of an M dwarf using e-MERLIN in conjunction with the Very Large Array (VLA), further demonstrating the growing importance of high-sensitivity radio interferometers in studying magnetism in these objects. Here, we discuss this new detection and its implications for our understanding of magnetic activity in low-mass stars.
