Formation and material supply of an active-region filament associated with newly emerging flux

With the observations of Solar Dynamics Observatory(SDO)/Atmospheric Imaging Assembly (AIA) 304 $\rm \mathring{\rm A}$ and New Vacuum Solar Telescope (NVST) H α bands, we present the formation of an active-region filament in active region NOAA 11903 during the period from 02:00 to 10:00 ut on 2013 November 25. A series of jets occurring in the vicinity of the south-western footpoint of the filament directly ejected cool and hot plasmas to filament height and supplied material for the filament. Some newly emerging flux is found in the vicinity of the south-western footpoint of the filament during these jets. In this paper, we mainly focus on the material supply for the formation of the filament. The plasma mass uploaded by the jets and the mass of the filament are estimated, which manifest the fact that the mass carried by the jets can supply sufficient material for the formation of the filament. We found two types of jets; one is H α jet, and the other is EUV jet. The significant finding is that some cool jets seen in the H α band but not in the SDO/AIA bands could also eject the cool material for the filament. These results suggest that cool plasma in the low atmosphere can be directly injected into the upper atmosphere and become the filament material by two types of jets. Moreover, the newly emerging flux with the non-potential field plays an important role in the appearance of the jets and the magnetic structure of the filament.
