The present study of the nature of the stars LkHα 112, LkHα 115, LkHα 118, and LkHα 119 is based on low-dispersion IDS spectra and photometric measurements in the wavelength range between 0.33 and 3.8 μm. These stars are located in the direction of the extremely young open cluster NGC 6530 (Walker, 1957). The purpose of this study is, in general, to know whether they belong to the group of intermediate mass pre-main sequence objects, also known as Herbig Ae/Be stars, and, in particular, what special characteristics they possess. The result is as follows. The stars are very young; probably only LkHα 112 and LkHα 115 are members of the above-mentioned class of objects. The membership of LkHα 118 and LkHα 119 in this group is doubtful.
