The extended atmosphere and circumstellar environment of the cool evolved star VX Sagittarii as seen by MATISSE
A. Chiavassa, K. Kravchenko, M. Montargès +50
Context. VX Sgr is a cool, evolved, and luminous red star whose stellar parameters are difficult to determine, which affects its classification. Aims. We aim to spatially resolve t…
Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE
V. Hocdé, N. Nardetto, A. Matter +149
The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…
The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?
J. Varga, M. Hogerheijde, R. van Boekel +133
Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…
VLTI/MIDI atlas of disks around low- and intermediate-mass young stellar objects
J. Varga, P. Ábrahám, L. Chen +13
Context. Protoplanetary disks show large diversity regarding their morphology and dust composition. With mid-infrared interferometry the thermal emission of disks can be spatially…
Mid-infrared interferometric variability of DG Tau: implications for the inner-disk structure
J. Varga, K. É. Gabányi, P. Ábrahám +12
Context. DG Tau is a low-mass pre-main sequence star, whose strongly accreting protoplanetary disk exhibits a so-far enigmatic behavior: its mid-infrared thermal emission is strong…
Design and development of a freeform active mirror for an astronomy application
Zalpha Challita, Tibor Agócs, Emmanuel Hugot +10
The advent of extremely large telescopes will bring unprecedented light-collecting power and spatial resolution, but it will also lead to a significant increase in the size and com…
