| 内容記述 | Optical and infrared photometry has been obtained for the two stars (RNO 90 and RNO 91) illuminating reflection nebulae in the small, filamentary dust cloud L 43. Spectrograms of RNO 90 in the blue and red have also been obtained, which show that it is a T Tauri star. Both stars have strong infrared excesses, placing them firmly in the 'dust' position of the H - K, K - L diagram. The absorption reversals superimposed on the Balmer lines from H-alpha to H-delta in RNO 90 display an interesting effect. They appear to move progressively redward from a position near the blue edge of the emission line at H-alpha to a nearly central location at H-delta. L 43 is located near the star-forming end of the Sco OB2 association, but is relatively isolated from the major center of activity, the Rho Oph cloud. There are a large number of similar-looking small clouds in its vicinity, only one of which is known to have an associated T Tauri star (AS 209). The complexity of this, the nearest star-forming region in an OB association, is illustrated. |
