Context: Several galaxies in the Virgo cluster are known to have large HI gastails related to a recent ram-pressure stripping event. The Virgo cluster hasbeen extensively observed at 1539 A in the far-ultraviolet for the GALEXUltraviolet Virgo Cluster Survey (GUViCS), and in the optical for the NextGeneration Virgo Survey (NGVS), allowing a study of the stellar emissionpotentially associated with the gas tails of 8 cluster members. On thetheoretical side, models of ram-pressure stripping events have started toinclude the physics of star formation. Aim: We aim to provide quantitativeconstraints on the amount of star formation taking place in the ram-pressurestripped gas, mainly on the basis of the far-UV emission found in the GUViCSimages in relation with the gas content of the tails. Methods: We haveperformed three comparisons of the young stars emission with the gas columndensity: visual, pixel-by-pixel and global. We have compared our results toother observational and theoretical studies. Results: We find that the level ofstar formation taking place in the gas stripped from galaxies by ram-pressureis low with respect to the available amount of gas. Star formation is lower byat least a factor 10 compared to the predictions of the Schmidt Law asdetermined in regular spiral galaxy disks. It is also lower than measured indwarfs galaxies and the outer regions of spirals, and than predicted by somenumerical simulations. We provide constraints on the star formation efficiencyin the ram-pressure stripped gas tails, and compare these with current models.
