Abstract:
The photometric and spectroscopic observations of IRAS 18062+2410 =
V886 Her, a candidate for protoplanetary objects, in 1996-1997 are
presented. The star exhibits rapid light variations with an amplitude
up to 0.3mag in V. A high-resolution spectrum of IRAS shows absorption
lines of H, HeI, OI, FeII, SiII, NaI and other species, including
[OII], [NII], and [FeII] that belong to the stellar envelope.
