Secondary eclipse observations allow the characterisation of the dayside of hot Jupiter exoplanet atmospheres. The standard, state of the art way of getting these observations is by using IRAC on the Spitzer Space Telescope. This instrument was not designed to reach the precision required to conduct these observations. However, it is possible to push IRAC to detect the secondary eclipse.

Il restauro e la conservazione dei beni librari ed archivistici sono stati considerati per molto tempo attivita` da espletare solo in laboratorio e quasi esclusivamente a vantaggio dei pezzi piu` preziosi, importanti o rappresentativi delle collezioni. Negli ultimi anni invece si sono affermate attivita` di conservazione che beneficino un grande numero di beni. Si e`, inoltre, finalmente imposta l’idea che

A solar eruption after a flare on 2011 June 7 produced EUV-bright impacts of fallbacks far from the eruption site, observed with the Solar Dynamics Observatory. These impacts can be taken as a template for the impact of stellar accretion flows. Broad redshifted UV lines have been commonly observed in young accreting stars. Here we study the emission from the

In this talk I want to report on my research activity during the past two years at INAF-OAPa, which has been focused on the study of systems with hot Jupiters. In particular, I will show how hot Jupiters can affect the activity of their host stars, in two examples: HD 189733 and WASP-18. I will briefly report on results from

I shall review some phenomena possibly related to the magnetic interaction between late-type stars and close-in massive planets and discuss models proposed for their interpretation. I shall consider the possible effects of hot Jupiters on stellar chromospheric emission and on stellar rotation. On the other hand, magnetic reconnection between stellar and planetary magnetic fields may enhance the evaporation of the

High energy photons produced in the acceleration regions of strong shocks, such as supernova remnants (SNR) or bow shocks formed by runaway stars, are suggested to have a non-thermal origin. However, the efficiency of these processes is still debated. Here we aim to develop a non-thermal model by appealing to a mixed leptonic-hadronic scenario to explain the observational data obtained
