The supernova remnant SN 1006 is a powerful source of high-energy particles and evolves in a tenuous and uniform environment. The X-ray image of SN 1006 reveals an indentation in the southwestern part of the shock front and the HI maps show an isolated cloud (hereafter southwestern cloud) whose morphology fits perfectly in the indentation. We performed spatially resolved spectral

 

 

One interesting question regarding the interaction between stars and planets and the birth of life is how the planetar atmosphere shields the stellar radiation. In particular, we expect that high energy radiation less penetrates into the planetary atmosphere. One implication is that, in principle, the planet should appear larger in a stellar transit observed in high energy bands. Venus transits

In un intreccio di letteratura, cinema, storia, astronomia e strumenti scientifici, verranno presentati i risultati di uno studio che prende le mosse da lavori precedenti condotti in collaborazione con Donata Randazzo e di recente estesi con alcuni contributi esterni ad OAPa, che spaziano fino ad una … inattesa conclusione.
