TL;DR: The HERMES high-resolution spectrograph project as discussed by the authors is based on the white-pupil beam folding for high resolution spectroscopy with a spectral resolution of 85'000 (63'000) for the low-resolution fiber.

TL;DR: The HERMES high-resolution spectrograph project as mentioned in this paper is based on the white-pupil beam folding for high resolution spectroscopy with a spectral coverage from 377 to 900nm in a single exposure.

TL;DR: PHOEBE as discussed by the authors is an open source modeling code for computing theoretical light and radial velocity curves that addresses both problems by incorporating missing physics and by increasing the computational fidelity, including triangulation as a superior surface discretization algorithm, meshing of rotating single stars, light travel time effects, advanced phase computation, volume conservation in eccentric orbits, and improved computation of local intensity across the stellar surfaces.

TL;DR: The detection of numerous gravity modes in a young star with a mass of about seven solar masses is reported, and the mean period spacing allows the extent of the convective core to be estimated and the clear periodic deviation from the mean constrains the location of the chemical transition zone to be at about 10 per cent of the radius.
