Peculiar outbursts of a black hole X-ray transient, V4641 Sgr
Abstract
We have kept optical monitoring of a peculiar black hole X-ray binary, V4641 Sgr. Based on our observations, we show that its unprecedented activity can be divided into 5 phases. In this paper, we report their observational properties.
