The magnetic field strength of a methane dwarf measured from its radio spectral cutoff
Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1
Brown dwarfs and gas-giant planets are expected to emit coherent radio emission via the electron cyclotron maser instability (ECMI) mechanism powered by non-thermal electrons in th…
Cradle of Life: From the Formation of Stars to Habitable Worlds with the SKAO
Eleonora Bianchi, Joseph R. Callingham, the Cradle of Life working group
The paper outlines how the Square Kilometre Array Observatory will be used to study the physical and chemical processes of star and planet formation, detect prebiotic molecules, ch…
Coherent and Incoherent Emission from the Ordered Magnetospheres of Low-Mass Stars, UCDs, and Massive Stars
Francesco Cavallaro, Paolo Leto, Barnali Das +15
Massive early-type (B/A) stars and ultracool dwarfs (UCDs) represent two distinct regimes in which ordered, large-scale magnetospheres are observed. In rapidly rotating massive sta…
The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
Constraining properties of dust formed in Wolf-Rayet binary WR 112 using mid-infrared and millimeter observations
Donglin Wu, Yinuo Han, Peredur M. Williams +9
Binaries that host a carbon-rich Wolf-Rayet (WC) star and an OB-type companion can be copious dust producers. Yet the properties of dust, particularly the grain size distribution,…
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…
