V1025 Her & V1071 Her: BVRI photometry, light curve solutions and absolute parameters estimation

Authors
Abstract:
We present BVRI observations of two not previously studied eclipsing binary stars. A significant number of times of minima was determined and therefore new more accurate ephemeredes were produced. Neither photometric elements nor spectral types for these two variable stars were known, thus a first approximation of their effective temperature and absolute magnitude was made by means of standard stars absolute photometry and using appropriate Teff, Mv – color index empirical relations.
