They are thought to play a crucial role in coronal heating and in the transfer of mass and energy through different atmospheric layers, including into the solar wind. Small-scale jets are generally classified into two types: (i) Standard jets, characterized by inverted Y-shaped structures, and (ii) Blow-out jets, which have broader spires and are often linked to mini-filament eruptions. In this work, we analyzed standard polar coronal hole jets using high-resolution data from the High Resolution Imager (HRI) onboard Solar Orbiter (SoLO). Our observations revealed a filament-like structure interacting with a jet, and we tracked the evolution of the jet and the filament material. The jets were also visible in the cooler temperature channels of the Atmospheric Imaging Assembly (AIA) and the Interface Region Imaging Spectrograph (IRIS), indicating the presence of both cooler and hotter plasma. The jets' energy is in the nanoflare range, typically associated with jets reaching heights of up to 5-10 Mm, but in this case, the jets extended up to 30 Mm above the limb. Additionally, we have analyzed the base of the jets to look for propagating blobs contributing to the dynamics of the jet. |
