Abstract

We present results from optical photometric and spectroscopic observations of the pre-main sequence star V 1184 Tau. The star is associated with the Bok globule CB 34 and it was considered as a FUOR candidate in previous studies. Our CCD photometric data () obtained from October 2000–April 2002 show non-periodic changes in the brightness with amplitude of about 0.6 (V). In the period of observations, V 1184 Tau remained at the maximum brightness without increasing or decreasing. Two medium dispersion optical spectra of V 1184 Tau were obtained in 2001. Significant changes in the profile and strength of the emission peak in the Hα line were found. The [OI] line (λ 6003) is also seen in emission while the sodium doublet is still in a deep absorption. The comparison of our photometric and spectroscopic results suggests that V 1184 Tau has the characteristics of a WTTS.
