title: Evolution of Luminous Non-Stable Stars
reg no: ETF5003
project type: Estonian Science Foundation research grant
subject: 1.4. Astronomy
status: completed
institution: Tartu Observatory
head of project: Tõnu Kipper
duration: 01.01.2002 - 31.12.2005
description: In 2002:

1) The spectral observations of the program stars with the 1.5 m telescope at the Tartu Observatory and
the Russian 6 m telescope. Photometric observations with the 0.6 m telescope.
2) Compilation of spectral atlases of representative objects for the spectral region 8500-8750 angstroms
proposed for GAIA mission.
3) Experiments with the spectral resolutions proposed for GAIA in order to choose optimal ones for the radial
velocity curves.
4) The studies of the possibilities for using WR stars as indicators of the extragalactic distances.
5) The spectroscopic studies of some nonvariable hydrogen deficient carbon stars (HdC) as background
objects for FG Sge, Sakurai's object and R CrB stars.
