Hard X-ray flux from low-mass stars in the Cygnus OB2 Association

M. Caramazza, J. J. Drake, G. Micela +1

Context. The Cygnus OB2 association, the central engine of the Cygnus X star-forming region, is the subject of an extensive INTEGRAL Key Project that will accumulate 6Ms of observa…

Multi-wavelength observing of a forming solar-like star

S. G. Gregory, E. Flaccomio, C. Argiroffi +7

V2129 Oph is a 1.35 solar mass classical T Tauri star, known to possess a strong and complex magnetic field. By extrapolating from an observationally derived magnetic surface map,…

Results from DROXO. II. - [Ne II] and X-ray emission from Rho Ophiuchi young stellar objects

E. Flaccomio, B. Stelzer, S. Sciortino +3

The infrared [Ne II] and [Ne III] fine structure lines at 12.81um and 15.55um are predicted to trace the circumstellar disk gas subject to X-ray heating and ionization. We investig…

On the classification of flaring states of blazar

E. Resconi, D. Franco, A. Gross +2

The time evolution of the electromagnetic emission from blazars, in particular high frequency peaked sources (HBLs), displays irregular activity not yet understood. In this work we…
