Review of coronal jets, and the Jet-Heliosphere Connection

While solar coronal jets were first extensively observed in the Yohkoh era of the 1990s, observations of
them in SDO during the 2010s and onward have provided fresh insights into their causes and nature.
Most of them are caused by eruptions of minifilaments, with at least many of those eruptions being
triggered by magnetic flux cancelations in the photosphere. Similar activity on larger-size scales
manifests as typical solar eruptions that result in filament eruptions, flares, and CMEs. In addition,
there is evidence that such activity also occurs on smaller-than-jet size scales too, resulting in
hard-to-observe (inconspicuous) coronal jets, the features known as "jetlets," and possibly
smaller (spicule-sized) features. We focus on connections, and possible connections, of jets and
jet-like features to heliospheric phenomena such as narrow CMEs (aka "white-light jets"),
polar plumes, magnetic switchbacks, and solar wind outflows. This presentation is supported by
