Detection of the planet using model templates of the full planet, H2O and CO using cross-correlation (top row) and the likelihood ratio (bottom row). The radial velocity is shown here in the barycentric restframe. In the top panel we also show the cross-correlation value for a reference spectrum, which was taken at the same separation on the other side of the star. In the bottom panels we indicate the location of the star and the planet and the expected velocity of the planet. -- astro-ph.IM

β Pictoris b Through The Eyes Of The Upgraded CRIRES+

by Keith CowingNovember 24, 2023November 24, 2023

Context: High-resolution spectrographs fed by adaptive optics (AO) provide a unique opportunity to characterize directly imaged exoplanets. Observations with such instruments allow us to probe the atmospheric composition, spin rotation, […]

Implementation of the FIM inside the IFS arm of SPHERE. On the left drawing, the SPHERE components are labelled in black, while the FIM components are labelled in red. The inset in the top right shows the components of the core optics bench. The light path in the system is fully illustrated in Vigan et al. (2022b, their Fig. 3). The picture on the right shows the FIM at the end of the installation in SPHERE. The IFS Lyot wheel is visible in the bottom left of the picture. -- astro-ph.EP

First Light of VLT/HiRISE: High-resolution Spectroscopy Of Young Giant Exoplanets

by Keith CowingNovember 17, 2023

A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer their formation processes […]
