An extended and refined grid of 3D STAGGER model atmospheres. Processed snapshots for stellar spectroscopy
Luisa F. Rodríguez Díaz, Cis Lagae, Anish M. Amarsi +6
Context: Traditional one-dimensional (1D) hydrostatic model atmospheres introduce systematic modelling errors into spectroscopic analyses of FGK-type stars. Aims: We present an upd…
Stellar granulation and interferometry
A. Chiavassa, L. Bigot
Stars are not smooth. Their photosphere is covered by a granulation pattern associated with the heat transport by convection. The convection-related surface structures have differe…
Fundamental properties of the Population II fiducial stars HD 122563 and Gmb 1830 from CHARA interferometric observations
O. L. Creevey, F. Thévenin, T. S. Boyajian +17
We have determined the angular diameters of two metal-poor stars, HD 122563 and Gmb 1830, using CHARA and Palomar Testbed Interferometer observations. For the giant star HD 122563,…
3D hydrodynamical model atmospheres: a tool to correct radial velocities and parallaxes for Gaia
A. Chiavassa, L. Bigot, F. Thevenin +4
Convection plays an essential role in the emerging intensity for many stars that will be observed by Gaia. Convective-related surface structures affect the shape, shift, and asymme…
