Abstract

1. Detection of nonthermal optical flares in low mass X-ray binaries. Eleven low-mass X-ray binaries have been observed with the MA¬NIA (Multichannel Analysis of Nanoseconds Intensity Alteration) complex; X0420+32, A0620-00, X1728-169, X1813-14, X1957+11 in 1986 at the 6 m telescope of SAO [7], and 2S0921-630, 4U1543-475, 4U1636-536, 4U1559-487, MXB1735-44, 4U1822-371 in 1991 at the 2.15 m telescope of CASLEO (Argentina) [1]. Analysis of the data using the special y 2 d 2 function formalism [4], [6] has shown no brightness variations on time-scales of 10-7… 10 s for all objects except A0620-00 and MXB1735-44.
