Circumstellar disk and ambient gas surrounding the protostar, L1489 IRS
Circumstellar disk and ambient gas surrounding the protostar, L1489 IRS (white cross), from an ALMA cycle-0 observation with an integration time of 74 minutes at a resolution of 1" (blue ellipse at the bottom right corner). The color scale shows the 1.3mm continuum emission. Streams of gas falling onto the disk (blue and red contours) are detected in C18O (2-1) emission, feeding both mass and angular momentum to the disk system. Prior to this observation, the infalling gas motion was not clearly resolved.
