Building the 'JMMC Stellar Diameters Catalog' using SearchCal

Lafrasse, Sylvain Mella, Guillaume Bonneau, Daniel

The JMMC Calibrator Workgroup has long developed methods to ascertain the angular diameter of stars, and provides this expertise in the SearchCal software. SearchCal dynamically finds calibrators near science objects by querying CDS hosted catalogs according to observational parameters. Initially limited to bright objects (K magnitude ≤ 5.5),...

Pseudomagnitudes and differential surface brightness: Application to the apparent diameter of stars

Chelli, Alain Duvert, Gilles Bourgès, Laurent

The diameter of a star is a major observable that serves to test the validity of stellar structure theories. It is also a difficult observable that is mostly obtained with indirect methods since the stars are so remote. Today only ~600 apparent star diameters have been measured by direct methods: optical interferometry and lunar occultations....
