The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
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…
The discovery space of ELT-ANDES. Stars and stellar populations
Ian U. Roederer, Julián D. Alvarado-Gómez, Carlos Allende Prieto +31
The ArmazoNes high Dispersion Echelle Spectrograph (ANDES) is the optical and near-infrared high-resolution echelle spectrograph envisioned for the European Extremely Large Telesco…
3D magneto-hydrodynamical simulations of stellar convective noise for improved exoplanet detection. I. Case of regularly sampled radial velocity observations
S. Sulis, D. Mary, L. Bigot
Convective motions at the stellar surface generate a stochastic colored noise source in the radial velocity (RV) data. This noise impedes the detection of small exoplanets. Moreove…
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…
A large sample of calibration stars for Gaia: log g from Kepler and CoRoT
O. L. Creevey, F. Thévenin, S. Basu +6
Asteroseismic data can be used to determine surface gravities with precisions of < 0.05 dex by using the global seismic quantities Deltanu and nu_max along with Teff and [Fe/H]. Su…
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…
