The dispersion in pulsar -ray efficiency

Daniel Íñiguez-Pascual, Daniele Viganò, Diego F. Torres

The observational efficiency of pulsars, defined as the ratio of the observationally derived isotropic-equivalent luminosity, , where is the average…

Magnetar Outburst Models with Cooling Simulations

D. De Grandis, N. Rea, K. Kovlakas +6

Magnetar outbursts are among the most noteworthy manifestations of magnetism in neutron stars. They are episodes in which the X-ray luminosity of a strongly magnetised neutron star…

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…

Synchro-curvature description of γ-ray light curves and spectra of pulsars: concurrent fitting

Daniel Íñiguez-Pascual, Diego F. Torres, Daniele Viganò

We present a concurrent fitting of spectra and light curves of the whole population of detected gamma-ray pulsars. Using a synchro-curvature model we compare our theoretical output…

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…
