ABSTRACT: Elias 29 is a Class I star of the young star forming site of the Rho Ophiuchi Dark Cloud.In X-rays it shows a prominent fluorescent line at 6.4 keV which origin is still to be clearly understood. The excitation of fluorescence of cold material could be due to hard X-ray photons especially produced during flares or to high energy electrons. I will report on a recent joint and simultaneous XMM + NuSTAR of about 300 ks meant to investigate X-rays from soft to hard band (approx. 0.3-80 keV). In particular, I will discuss the analysis of a bright flare of modest duration (20 ks), the fluorescent emission and its variability and the hard X-ray emission in the NuSTAR band (10-80 keV).

Lo studente Vincenzo Sapienza presenta il suo lavoro di tesi per la Laurea Triennale.

Partendo da analisi di tipo sociologico e statistico del XX secolo, saranno discusse le difficoltà incontrate dalle donne nella carriera scientifica e le potenzialità del loro contributo allo sviluppo della scienza.
