  This booklet contains a collection of contributions to the meeting of the
JEts and Disks at INAF (JEDI) group, which took place at the Capodimonte
Observatory during 9-10 April 2015. Scope of the meeting was to bring together
the JEDI researchers of the Italian Istituto Nazionale di Astrofisica (INAF)
working in the field of circumstellar disks and jets in young stars, to discuss
together the different agents affecting the structure and the evolution of
disks, namely accretion, jets and winds. More information on the JEDI group and
its activities can be found at
