Inflated hot Jupiters: Inferring average atmospheric velocity via Ohmic models coupled with internal dynamo evolution
Daniele Viganò, Soumya Sengupta, Clà udia Soriano-Guerrero +4
The inflated radii observed in hundreds of hot Jupiters (HJ) represent a long-standing open issue. In this study, we quantitatively investigate this phenomenon within the framework…
Kilonova constraints for the LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: GW-MMADS observations
Lei Hu, Tomás Cabrera, Antonella Palmese +35
Gravitational wave (GW) neutron star mergers with an associated electromagnetic counterpart constitute powerful probes of binary evolution, the production sites of heavy elements,…
Non-ideal MHD simulations of hot Jupiter atmospheres
Clà udia Soriano-Guerrero, Daniele Viganò, Rosalba Perna +2
In Hot Jupiters (HJs), atmospherically induced magnetic fields are expected to play an important role in controlling the wind circulation and in determining their inflated radii. H…
The role of Ohmic dissipation of internal currents on Hot Jupiter radii
Taner Akgün, Clà udia Soriano-Guerrero, Albert Elias-López +3
The inflated radii observed in hundreds of Hot Jupiters represent a long-standing open issue. The observed correlation between radii and irradiation strength, and the occasional ex…
The infrared counterpart and proper motion of magnetar SGR0501+4516
A. A. Chrimes, A. J. Levan, J. D. Lyman +19
Soft gamma repeaters (SGRs) are highly magnetised neutron stars (magnetars) notable for their gamma-ray and X-ray outbursts. In this paper, we use near-infrared (NIR) imaging of SG…
Incidence of afterglow plateaus in gamma-ray bursts associated with binary neutron star mergers
Luca Guglielmi, Giulia Stratta, Simone Dall'Osso +3
One of the most surprising gamma-ray burst (GRB) features discovered with the Swift-X ray telescope (XRT) is a plateau phase in the early X-ray afterglow light curves. These platea…
