Time evolution of magnetic activity cycles in young suns: The curious case of kappa Ceti

S. Boro Saikia, T. Lueftinger, C. P. Folsom +15

A detailed investigation of the magnetic properties of young Sun-like stars can provide valuable information on our Sun's magnetic past and its impact on the early Earth. We determ…

Discovery of optical flickering from the symbiotic star EF Aquilae

R. K. Zamanov, S. Boeva, Y. M. Nikolov +9

We report optical CCD photometry of the recently identified symbiotic star EF Aql. Our observations in Johnson V and B bands clearly show the presence of stochastic light variation…

Modelling the environment around five ultracool dwarfs via the radio domain

Y. T. Metodieva, A. A. Kuznetsov, A. E. Antonova +3

We present the results of a series of short radio observations of six ultracool dwarfs made using the upgraded VLA in S (2--4GHz) and C (4--7GHz) bands. LSR J1835+3259 exhibits a 1…

Magnetospherically driven optical and radio aurorae at the end of the stellar main sequence

G. Hallinan, S. P. Littlefair, G. Cotter +12

Aurorae are detected from all the magnetized planets in our Solar System, including Earth. They are powered by magnetospheric current systems that lead to the precipitation of ener…
