VizieR Online Data Catalog: LkHα 330 SPHERE/VLT and ALMA images (Pinilla+, 2022)
Abstract
We obtained observations of LkHα 330 at the Very Large Telescope located at Cerro Paranal, Chile, using the SPHERE instrument, a high-contrast imager with an extreme adaptive optics system under program IDs 098.C-0760(B) and 100.C-0452(A) (PI: M. Benisty). In this paper, we report new polarimetric observations taken on 2017-10-05 and 2017-10-11 and obtained in the near-infrared (J- (1.2um) and H- (1.65um), respectively) with the IRDIS instrument. For all the IRDIS observations presented in this paper, we use a 185 mas diameter coronagraph (NALCYJH_S) to enhance the signal-to-noise ratio in the outer disk regions. The plate scale is 12.26mas and 12.25mas per pixel, for the J- and H- band data, respectively.
