Automated Determination of Stellar Parameters from Simulated Dispersed Images for DIVA
P. G. Willemsen, C. A. L. Bailer-Jones, T. A. Kaempf +1
We have assessed how well stellar parameters (T_eff, logg and [Fe/H]) can be retrieved from low-resolution dispersed images to be obtained by the DIVA satellite. Although DIVA is p…
