Abstract:
Present knowledge of the solar spectrum is limited because it is very
difficult to observe the integrated solar spectrum at high resolution.
The reflected solar light from asteroids has been shown to provide a
relatively straightforward integrated and unmodified solar spectrum.
We exploit this methodology to improve our knowledge of solar
photospheric line positions both in terms of line number and precision
with respect to the available solar line atlas.
Description:
The DAOSPEC program is used to measure solar line positions
automatically in high signal-to-noise spectra of Ceres obtained with
HARPS at the 3.6m ESO telescope, they are compared with the Allende
Prieto line list and the difference in RV is reported.
