Scientific paper

In this poster we present the detection of four new variable stars in NGC4755. NGC4755-116 is most probably a double mode Cepheid with two low frequencies at 0.17 and 0.24/d. NGC4755-405 can be considered as a new beta Cephei star with two pulsation frequencies. For NGC4755-215 we found one frequency and for NGC4755-316 three pulsation frequencies which are slightly too long for beta Cephei stars.
