Offer Description The Interferometric Survey of Stellar Parameters (ISSP) ERC-Adv grant, started on 1 Sep 2021 for 5 years, aims at realizing and exploiting an ambitious and homogenous survey of the angular diameters of a thousand stars as faint as magnitude 8 in the visible and as small as 0.2 milliseconds of arc. It takes benefit of the recently commissioned CHARA/SPICA instrument installed on the CHARA Array, Mount Wilson Observatory (USA, CA). The survey is built to address key questions about the relation between planets and stars and to offer to the broader community a unique and primary source of direct information on a representative and large sample of stars all over the HR diagram. The ISSP team is opening this postdoc position to support the scientific programs of the survey through a dedicated effort on the fringe tracking facility and image reconstruction.
This position is focused on the imaging part of the survey, mainly related to the subprograms S05 (limb darkening), S06 (binary), S07 (fast rotators) and S08 (disks and winds). The goal is to open the possibility of image reconstruction combining R-band data (SPICA-VIS), H-band data (MIRCx) and K-band data (MYSTIC), using the three instruments simultaneously with the 15 baselines of CHARA. To reach the required performance for the different programs, we need to have a fully operational fringe tracker, called SPICA-FT, and that can be operated routinely every night.
