Orbital motion and dynamical mass of the complex periodic variable binary system 2MASS J05082729-2101444
S. Curiel, G. N. Ortiz-León, V. J. S. Béjar +22
We used very long baseline interferometry to constrain the orbit of the binary system 2MASS J05082729-2101444. We observed the system with the VLBA in three epochs at a frequency o…
Searching for radio emission from stellar wind-magnetosphere interaction or co-rotation breakdown in brown dwarfs
Rebeca Pirvu Malanda, Simranpreet Kaur, Daniele Viganò +11
With the improvements in radio interferometry sensitivity, the quest for coherent radio emission from exoplanets and ultra-cool dwarfs, which is indicative of their magnetic fields…
Polarized, variable radio emission from the scallop-shell binary system DG CVn
Simranpreet Kaur, Daniele Viganò, Jackie Villadsen +9
DG CVn is an eruptive variable star and represents the closest member of the known sample of complex periodic variables, or scallop-shell stars. Over the years, this M dwarf binary…
Rossby number regime, convection suppression, and dynamo-generated magnetism in inflated hot Jupiters
Albert Elias-López, Matteo Cantiello, Daniele Viganò +3
Hot Jupiters (HJs) are commonly thought to host the strongest dynamo-generated magnetic fields among exoplanets, up to one order of magnitude larger than Jupiter. Thus, they have o…
Planetary Dynamos in Evolving Cold Gas Giants
Albert Elias-López, Fabio Del Sordo, Daniele Viganò +4
Magnetic fields remain one of the least understood aspects of exoplanetary systems. A deeper understanding of planetary dynamos and the evolution of surface magnetic properties thr…
First detection of variable radio emission originating from the infant planetary system V1298 Tau
M. Damasso, O. Morata, S. Kaur +13
V1298 Tau is a very young and magnetically active star which hosts a benchmark multi-planetary system to study planet formation and evolutionary history at the earliest stages. We…
