Planet transit and stellar granulation detection with interferometry: Using the three-dimensional stellar atmosphere S tagger -grid simulations

Chiavassa, A; Ligi, R.; Magic, Zazralt; Collet, Remo; Asplund, Martin; Mourard, D.

Description

Context. Stellar activity and, in particular, convection-related surface structures, potentially cause bias in planet detection and characterisation. In the latter, interferometry can help disentangle the signal of the transiting planet. Aims. We used realistic three-dimensional (3D) radiative hydrodynamical (RHD) simulations from the Stagger-grid and synthetic images computed with the radiative transfer code Optim3D to provide interferometric observables to extract the signature of stellar...[Show more]
