Abstract: | Spectral observations of the subfuor (exor) V 1143 Ori during the outburst of 1992-93 are reported. Data on the behavior of the Ca II infrared triplet before and during the outburst are presented for the first time. The amplitudes of the outbursts during 1982-94 show that their maxima do not vary greatly on the average. Between outbursts, when the star is in the minimum of its active period, the spectrum of V 1143 Ori is typical of a WTTS and during an outburst, of a CTTS. |
