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).

Prova Tesi V. Sapienza

Tickets

Mar 1 @ 15:00 – 16:00

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

Egli si e` occupato dell’analisi e dell’interpretazione di due flares di stelle di tipo WTT appartenenti alla regione di Rho Ophiuchi. Ha derivato le caratteristiche della loop del flare e di altre grandezze fisiche del fenomeno applicando le diagnostiche sviluppate in Reale (2007). Il lavoro e` stato svolto sotto la supervisione di I. Pillitteri e del prof. G. Peres (relatore presso UNIPA)
