Ogloza, W.; Conidis, G. J.; Gazeas, K. D. +1 more

Three short period (P ∼ 1 day) variable stars from the Hipparcos catalogue targets were observed after suspected misclassification as Beta Lyr eclipsing systems (Perryman et al. 1997), as no secondary component had been noticed in the inspection of their Broadening Functions (BFs) (Rucinski 2002). FH Cam is found to be a multiple star system with …

Photometric observations and frequency analysis of the Delta Scuti star IP UMa

Gavras, P.; Sinachopoulos, D.; Ducourant, Chr.

IP UMa is a Delta Scuti star discovered by Hipparcos. 2642 observations of this target were acquired with the 20cm telescope of the Nea Lesbos Observatory in 10 nights from June 2 to July 9, 2009 using the Bessel V filter. These data confirmed the pulsation frequency of the star listed in the Hipparcos Catalogue (10 c/d).
