Mid-infrared photometry of the T Tauri triple system with kernel phase interferometry

no code implementations21 Dec 2020 J. Kammerer, M. Kasper, M. J. Ireland, R. Köhler, R. Laugier, F. Martinache, R. Siebenmorgen, M. E. van den Ancker, R. van Boekel, T. M. Herbst, E. Pantin, H. -U. Käufl, D. J. M. Petit dit de la Roche, V. D. Ivanov

We aim to measure the brightness of all three components of the T Tauri system (T Tau N, T Tau Sa, T Tau Sb) in the mid-infrared in order to obtain photometry around the $\sim 9. 7~\mu m$ silicate feature.

Design, pointing control, and on-sky performance of the mid-infrared vortex coronagraph for the VLT/NEAR experiment

no code implementations15 Dec 2020 A. -L. Maire, E. Huby, O. Absil, G. Zins, M. Kasper, C. Delacroix, S. Leveratto, M. Karlsson, G. Ruane, H. -U. Käufl, G. Orban de Xivry, P. Pathak, L. Pettazzi, P. Duhoux, J. Kolb, E. Pantin, A. J. Eldorado Riggs, R. Siebenmorgen, D. Mawet

Here, we present the design of the mid-IR vortex coronagraph for the new Earths in the $\alpha$ Cen Region (NEAR) experiment with the VLT/VISIR instrument and assess the performance of the QACITS estimator for the centering control of the star image onto the vortex coronagraph.
