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…
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…
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…
Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J050827292101444
Simranpreet Kaur, Daniele Viganò, Víctor J. S. Béjar +18
Scallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are sta…
Variable, circularly polarized radio emission from the Young Stellar Object [BHB2007]-1: another ingredient of a unique system
Simranpreet Kaur, Josep M. Girart, Daniele Viganò +7
The young stellar object [BHB2007]-1 has been extensively studied in the past at radio, millimeter, and infrared wavelengths. It shows a gap in the disk and previous observations c…
Vorticity and magnetic dynamo from subsonic expansion waves II: Dependence on magnetic Prandtl number, forcing scale, cooling time
Albert Elias-López, Fabio del Sordo, Daniele Viganò
The amplification of astrophysical magnetic fields takes place via dynamo instability in turbulent environments. The presence of vorticity is crucial for the dynamo to happen. Howe…
The CARMENES search for exoplanets around M dwarfs. A long-period planet around GJ 1151 measured with CARMENES and HARPS-N data
J. Blanco-Pozo, M. Perger, M. Damasso +37
Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet science. Recently, a tantalisi…
Population synthesis of isolated Neutron Stars with magneto--rotational evolution
Miguel Gullón, Juan A. Miralles, Daniele Viganò +1
We revisit the population synthesis of isolated radio-pulsars incorporating recent advances on the evolution of the magnetic field and the angle between the magnetic and rotational…
