We present VI -band photometry for stars in the metal-rich globular cluster NGC 6496 .
Our time-series data were cadenced to search for long period variables ( LPVs ) over a span of nearly two years , and our variability search yielded the discovery of thirteen new variable stars , of which six are LPVs , two are suspected LPVs , and five are short period eclipsing binaries .
An additional star was found in the ASAS database , and we clarify its type and period .
We argue that all of the eclipsing binaries are field stars , while 5-6 of the LPVs are members of NGC 6496 .
We compare the period-luminosity distribution of these LPVs with those of LPVs in the Large Magellanic Cloud and 47 Tucanae , and with theoretical pulsation models .
We also present a VI color magnitude diagram , display the evolutionary states of the variables , and match isochrones to determine a reddening of E ( B - V ) = 0.21 \pm 0.02 mag and apparent distance modulus of 15.60 \pm 0.15 mag .
