HH 30

HH-30 (also V1213 Tauri) is an edge-on protoplanetary disk that is surrounded by jets and a disk wind. HH-30 is located in the dark cloud LDN 1551 in the Taurus Molecular Cloud. The HH-30 disk is the prototype of an edge-on disk, due to its early discovery with Hubble. Discovery HH 30 was published by George Herbig in 1974 in the "Draft Catalog of Herbig–Haro Objects" and notes: "HH-30 (4h 28m 44s) is a small, almost stellar spot 2' south of XZ and HL Tau. There is a fainter nebulosity immediately northeast. The small fuzzy spot of very similar appearance at 35" in 250° from HL Tau is not a HH Object, but a star having Hα in emission." In 1996 it became clear that the object is an edge-on protoplanetary disk with jets. The central star The star is hidden behind the dust of the disk. The spectral type was measured around M0 with the Keck Observatory, corresponding to a temperature...
