On Possible Extension of the Vilnius Photometric System Into the Ultraviolet and the Near Infrared
Abstract
The Vilnius seven-color medium band photometric system was chosen as the most effective one for the future Russian astrometric and photometric space project STRUVE (the former name was AIST). The location of telescopes in space allows to add to the Vilnius system three more ultraviolet passbands with medium wavelengths at 282, 247 and 218 nm and with half-widths of 15, 28 and 40 nm, respectively. The main goals of this extension of the system are: better possiblities for classification of stars earlier than F, especially, early B and O-type stars, peculiar stars of types Bp, Ap, Am, Be, etc., and further investigation of features of the interstellar extinction law in the ultraviolet.
