Scientific paper

A 2-micron continuum source with one of the six dense cores in NGC 2024 found by Mezger at al. (1988) has been detected and interpreted as cold, isothermal protostars. The new source is highly reddened (H-K greater or equal to 3.8) and quite faint (S(K) = 8.3 x 10 to the -15th/sq Wm per micron) and provides clear evidence that at least one of these cores contains a hot, embedded young star. Accompanying the point-like near-IR source is a compact unipolar nebula which has features common to the IR reflection nebulae associated with outflows from young sources.
