Long-term photometric behavior of the eclipsing cataclysmic variable
  V729 Sgr
  We present the analysis results of an eclipsing cataclysmic variable (CV)
V729 Sgr, based on our observations and AAVSO data. Some outburst parameters
were determined such as outburst amplitude ($A_{n}$) and recurrence time
($T_{n}$), and then the relationship between $A_{n}$ and $T_{n}$ is discussed.
A cursory examination for the long-term light curves reveals that there are
small-amplitude outbursts and dips present, which is similar to the behaviors
seen in some nova-like CVs (NLs). More detailed inspection suggests that the
outbursts in V729 Sgr may be Type A (outside-in) with a rise time $\sim1.76$ d.
Further analysis also shows that V729 Sgr is an intermediate between dwarf nova
and NLs, and we constrain its mass transfer rate to $1.59\times10^{-9} <
\dot{M}_{2} < 5.8\times10^{-9}M_{\odot}yr^{-1}$ by combining the theory for Z
Cam type stars with observations. Moreover, the rapid oscillations in V729 Sgr
were detected and analyzed for the first time. Our results indicate that the
oscillation at $\sim 25.5$ s is a true DNO, being associated with the accretion
events. The classification of the oscillations at $\sim 136$ and $154$ s as
lpDNOs is based on the relation between $P_{lpDNOs}$ and $P_{DNOs}$. Meanwhile,
the QPOs at the period of hundreds of seconds are also detected.
