Phenomenology and periodicity of radio emission from the stellar system AU Microscopii

Sanne Bloot, Joseph R. Callingham, Harish K. Vedantham +6

Stellar radio emission can measure a star's magnetic field strength and structure, plasma density and dynamics, and the stellar wind pressure impinging on exoplanet atmospheres. Ho…

Radio emission as a stellar activity indicator

Timothy W. H. Yiu, Harish K. Vedantham, Joseph R. Callingham +1

Radio observations of stars trace the plasma conditions and magnetic field properties of stellar magnetospheres and coronae. Depending on the plasma conditions at the emitter site,…

Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b

Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18

The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…

No strong radio absorption detected in the low-frequency spectra of radio-loud quasars at z > 5.6

A. J. Gloudemans, A. Saxena, H. Intema +7

We present the low-frequency radio spectra of 9 high-redshift quasars at using the Giant Metre Radio Telescope band-3, -4, and -5 observations (300-1200…

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…

Polarised radio pulsations from a new T dwarf binary

H. K. Vedantham, Trent J. Dupuy, E. L. Evans +6

Brown dwarfs display Jupiter-like auroral phenomena such as magnetospheric H emission and coherent radio emission. Coherent radio emission is a probe of magnetospheric accelerat…
