	6	Spectroscopic study of Be-shell stars:4 Her and 88 Her显示文摘We present an optical spectroscopic study based on 41 spectra of 4 Her and 32 spectra of 88 Her,obtained over a period of 6 months.We estimate the rotational velocity of these stars from Hel lines in the blue spectral region(4000-4500 ?).We find that these stars are likely to be rotating at a fractional critical rotation of^0.80.We measure the average I_p/I_c ratio to quantify the strength of the Hα line and obtain1.63 for 4 Her and 2.06 for 88 Her.The radius of the Ha emission region is estimated to be R_d/R_*~5.0,assuming a Keplerian disk.These stars are thus found to be fast rotators with a relatively small Ha emission region.We detect V/R variation of the Ha spectral line during the observed period.We re-estimate the periods for both stars and obtain a period of ~46 d and its harmonic of 23.095 d for 4 Her,and a period of^86 d for 88 Her.As these two cases are shell stars with binaries and have low Ha EW with the emission region closer to the central star,the V/R variation and a change in period may be an effect of the binary on the circumstellar disk.
