Abstract:
HD 19467 observations were performed with the VLT exoplanet imager SPHERE
and the VLT adaptive optics camera NaCo to further characterize the
spectral and orbital properties of the known T-type brown dwarf companion.
Description:
The SPHERE and NaCo high-contrast images processed with angular
differential imaging are provided. The SPHERE and NaCo/Lp images were
processed with TLOCI-ADI (see Galicher et al., 2018A&A...615A..92G 2018A&A...615A..92G)
and are normalized to the stellar peak (contrast with respect to the
star). The NaCo/Mp image was processed with PCA (see Cheetham et al.,
2019A&A...622A..80C 2019A&A...622A..80C).
