The Estimation of the Electron Density ne with a Narrow-Band Photometric System Calibrated by Model Atmospheres

  • M. Gerbaldi (a1) (a2) and N. Morguleff (a1)

Extract

A spectrophotometer was originally designed by Barbier (1960) for the study of early-type stars. The band passes were chosen to measure the features of the hydrogen spectrum. To the first definition of the system (Barbier and Morguleff 1964), two more bands were added, specifically devoted to the peculiar stars of type Ap and Am (Gerbaldi 1972). The interpretation of these observations has already been given separately. We will concentrate here on the calibration of this spectrophotometric system in terms of Teff, log g and electron density ne.
