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…
