Abstract:We present K_s_-band light curves for 299 Cepheids in the Small Magellanic Cloud (SMC) of which 288 are new discoveries that we have identified using multi-epoch near-infrared photometry obtained by the VISTA survey of the Magellanic Clouds system (VMC). The new Cepheids have periods in the range from 0.34 to 9.1d and cover the magnitude interval 12.9<=

We have developed a technique to identify variable stars using only
the multi-epoch near-infrared photometry obtained by the VMC survey
and have specifically tailored it to the identification of Cepheids.
The technique exploits colour-magnitude and colour-colour
diagrams, and PL relations defined by known SMC Cepheids, along with
template parameter selections and visual inspection of the light curve
to identify bona fide Cepheids. The technique was applied to external
regions of the SMC for which complete VMC Ks-band observations are
available and no comprehensive identification of variable stars from
other surveys exists yet. We have identified and present Ks-band light
curves for 299 SMC Cepheids.
