ASCA observation of the low-luminosity Seyfert 1.5 galaxy NGC 5033

We present the results of an ASCA observation of the low-luminosity Seyfert 1.5 galaxy NGC 5033. A point-like X-ray source with a luminosity of 2.3 x 10(41) erg s(-1) in the 2-10 keV band (at 18.7 Mpc; Tully 1988, AAA 045.002 .054) was detected at the nucleus. The X-ray light curve shows variability on a timescale of similar to 10(4) s With an amplitude of similar to 20%. T he X-ray continuum is represented by a weakly absorbed (N-H approximate to 9 x 10(20) cm(-2)) power-law with a photon index of 1.72 +/- 0.04, which is quite similar to Seyfert 1 galaxies with higher luminosities. An Fe K alph a emission line is detected at 6.40(-0.06)(+0.08) keV (redshift corrected) and the equivalent width is 290 +/- 100 eV. The line width is unresolved. T he narrower line width and larger equivalent width compared to Seyfert Is i mply that fluorescent Fe K alpha emission from matter further out from the center than the accretion disk significantly contributes to the observed Fe K alpha line. We suggest that fluorescent Fe K alpha emission from the put ative torus contributes to the observed Fe K alpha line.
