Description:
We present the second part of the Hamburg/SAO Survey for Emission-Line
Galaxies (HSS therein, SAO - Special Astrophysical Observatory,
Russia) which is based on the digitized objective-prism photoplates
database of the Hamburg Quasar Survey (HQS). The main goal of the
project is the search for emission-line galaxies (ELG) in order to
create a new deep sample of blue compact/HII galaxies (BCG) in a large
sky area. Another important goal of this work is to search for new
extremely low-metallicity galaxies. In this paper we present new
results of spectroscopy obtained with the 6m Russian telescope. The
main ELG candidate selection criteria applied are blue or flat enough
continuum (near 4000A) and the presence of strong or moderate emission
lines close to 5000A recognized on digitized prism spectra of galaxies
with the survey estimated B-magnitudes in the range 16 - 19.5. No
other criteria were applied. The spectroscopy resulted in detection
and quantitative spectral classification of 134 emission-line objects.
For 121 of them the redshifts are determined for the first time. For
13 ELGs known before emission line ratios are presented at first time.
108 of 134 emission-line objects are classified as BCG/HII galaxies
and 6 probable BCGs, 6 as QSOs, 1 as Seyfert galaxy, 1 as
super-association in a dwarf spiral galaxy, 2 as probable LINERs, 14
are low excitation objects - either of starburst nuclei (SBN), or
dwarf amorphous nuclei starburst galaxy (DANS) type -, and 1
nonclassified. 23 galaxies did not show significant emission lines.
The five most metal-deficient BCGs discovered have oxygen abundances
log(O/H)+12 in the range 7.4 to 7.7, similar to the most
metal-deficient BCGs known before.
