A Jupiter-like radio aurora in the L3.5 dwarf LSPM J0036+1821

D. Martín-Carrero, J. B. Climent, P. A. Miles-Páez +6

Ultracool dwarfs exhibit radio emission revealing strong magnetic fields and complex magnetospheric processes. Their auroral emission resembles that observed in magnetized Solar Sy…

Can Auroral Heating Explain Brown Dwarf Thermal Inversions?

Anna Zuckerman, James Mang, J. Sebastian Pineda +2

Recent modeling of the JWST spectra of the Y-dwarf CWISEPJ193518.59-154620.3 (Faherty et al. 2024; Suárez et al. 2025) and the T-dwarf SIMPJ013656.5+093347.3 (Nasedkin et al. 2025)…

The MegaWave Radio Surveyor

T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40

Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…

Discovering and Characterising Exoplanets and Ultracool Dwarfs with the Square Kilometre Array

Robert D. Kavanagh, Juan B. Climent, Philippe Zarka +14

The majority of the Solar System planets are sources of bright radio emission, driven by energetic electrons trapped within each planet's magnetic field. Detection of this emission…

Simulations of Electron Beam Interactions in Brown Dwarf Atmospheres

Anna Zuckerman, J. Sebastian Pineda, David Brain +2

Over two decades ago, the first detection of electron cyclotron maser instability (ECMI) radio emission from a brown dwarf confirmed the presence of aurorally precipitating electro…

Evaluating Star-Planet Interactions with Zeeman Doppler Imaging: Case Study in YZ Ceti

J. Sebastian Pineda, Stefano Bellotti, Jackie Villadsen +3

The recent detections of radio emission from the nearby exoplanet host, YZ Ceti, suggest that the star is possibly interacting with its rocky innermost planet. These radio emission…

Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather

J. R. Callingham, B. J. S. Pope, R. D. Kavanagh +22

Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain…

Plausible association of distant late M dwarfs with low-frequency radio emission

A. J. Gloudemans, J. R. Callingham, K. J. Duncan +10

We present the serendipitous discovery of 8 distant ( 50 pc) late M dwarfs with plausible associated radio emission at 144 MHz. The M dwarf nature of our sources has been confir…

Radio Emission from Binary Ultracool Dwarf Systems

Melodie M. Kao, J. Sebastian Pineda

Well-characterized binary systems will provide valuable opportunities to study the conditions that are necessary for the onset of both auroral and non-auroral magnetospheric radio…

A Survey for H-alpha Emission from Late L dwarfs and T dwarfs

J. Sebastian Pineda, Gregg Hallinan, J. Davy Kirkpatrick +3

Recently, studies of brown dwarfs have demonstrated that they possess strong magnetic fields and have the potential to produce radio and optical auroral emissions powered by magnet…
