Erratum: “Study of the optical variability of T Tau in the period 1962–2003” [Astron. Lett. 31 (2), 109 (2005)] (original) (raw)

We present the results of our long-term U BV R observations of the star T Tauri performed at Mt. Maidanak Observatory from 1986 until 2003. These data, together with previous photoelectric observations of other authors, suggest that the long-term variations of the light curve are not periodic, but have a cycle with a time scale of 6-9 yr. The light curve also exhibits slower variations with time scales of ∼30-40 yr. We confirm the existence of periodic brightness variations with a period of P = 2 d .798 over many years; this process is peculiar in that the phase and shape of the phase curve change from season to season. We analyze the color behavior of the star. We found evidence of a strong flare occurred on October 5, 1999, when the brightness of the star reached 9 m . 22. This is the strongest flare recorded during its photoelectric observations. c 2005 Pleiades Publishing, Inc.
