Coronal ejective events, as well as the regular solar wind, expel plasma from the Sun into the interplanetary medium. The link between the solar sources and the interplanetary consequences of these two phenomena will be reviewed in this talk. Interplanetary coronal mass ejections (ICMEs) are considered to be the interplanetary counterparts of coronal mass ejections (CMEs). The association between both phenomena is determined taking into account the CME source region position on the Sun, the time delay expected between the CME initiation and "in situ" observations, and/or by comparing the orientation of the coronal and interplanetary \in situ" magnetic elds. Several recent studies have analysed this connection in a more quantitative way, combining multi-wavelength remote sensing and \in situ" data, together with magnetic eld modelling in both domains. On the other hand, the sources of the slow solar wind have been searched for by determining the topological origin of active region outows in solar spectrometer data and their traces in \in situ" measurements. We will discuss the trends found in both kinds of studies and how these analyses can help us to constrain our modeling, both at the coronal level and in the interplanetary space.
