VizieR Online Data Catalog: KELT-9 radial velocity with LBT/PEPSI (Pai Asnodkar+, 2022)

We observed two transits of KELT-9 b with the high-resolution echelle spectrograph Polarimetric and Spectroscopic Instrument (PEPSI) on the Large Binocular Telescope (LBT) (two 8.4m mirrors, effective aperture of 11.8m) in Arizona. PEPSI has a blue arm (nominally 3830-5440Å) and a red arm (nominally 5440-9070Å) with six cross-dispersers for full optical coverage. In this work, we use high-resolution data from the blue arm taken with cross-disperser 3 (~4750-5430Å, R=50000) exclusively because of negligible telluric contamination.

In this work, we apply the classical techniques used to analyze SB2s to the KELT-9 system using observations from PEPSI spectrograph on LBT and the HARPS-N spectrograph on the Telescopio Nazionale Galileo (TNG). We utilize the original Tillinghast Reflector Echelle Spectrograph (TRES) data (Gaudi+, 2017Natur.546..514G) as well as additional velocities from higher-precision spectrographs.
