Özet

We present the results of a photometric campaign of the dwarf nova V1040 Cen. The light curve shows two normal outbursts with recurrence time approximate to 40 days and amplitude approximate to 2.5 mag. Quiescence data show oscillations with periods in the range approximate to 0.1 days (2.4 h) to approximate to 0.5 days (12 h) of unknown origin. We measured the orbital period of V1040 Cen to be P(orb) = 0.060458(80) days (1.451 +/- 0.002 h). Based on the M(V)-P(orb) relation we found the distance of V1040 Cen to be 137 +/- 31 pc. In this paper we also report the detection of eleven new variable stars in the field of the monitored dwarf nova.
