Job Announcement Text: 

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. It takes benefit of the 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.

This position is focused on the S01 SPICA program aiming at obtaining direct interferometric measurements of stars known to hosting exoplanets. This program is closely related to the ESA PLATO mission for which CHARA/SPICA aims at producing reliable interferometric measurements before the operation (extraction of non-seismic parameters of stars in the PLATO Input Catalog) and during the operation through follow-up programs. About 50 stars have been identified as targets for CHARA/SPICA and we expect more in the coming years with the advent of new discoveries. The goal is to develop reliable methods for the determination of ages and masses of Stars and Planets and to provide reliable and model-independent determination of radius and temperature. Managing this observing program will be one of the main topics of this position, together with the co-investigators of the ISSP survey. The second main aspect will be to interpret these interferometric determinations together with known parameters from the literature and with the use of existing stellar evolution models. This method will be used for others CHARA/SPICA programs based also on angular diameter measurements.
