Abstract:
We present the results of a neutral hydrogen survey conducted with the
100-m radiotelescope at Effelsberg of 44 northern objects in the
polar-ring galaxy atlas of Whitmore et al. (1990AJ....100.1489W 1990AJ....100.1489W).
These observations were performed to complement the Green Bank
observations of polar-ring galaxies (Paper I, 1994AJ....107...99R 1994AJ....107...99R). We
detected 29 of these above our detection limit of a few mJy. The
relative content of neutral hydrogen (MHI/LB) of the early-type
galaxies (E, S0) in this sample is significantly higher than for
galaxies of the same morphological types from comparison samples, i.e.
for elliptical galaxies MHI/LB=0.17±0.09 and for S0 galaxies
MHI/LB=0.75±0.13 which is about 6 times the mean value from the
comparison samples for the same morphological types.
