VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris
K. -H. Hofmann, A. Bensberg, D. Schertl +58
Context: FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk. The evolutionary stage of FS CMa is still debated. Perpendicular to t…
HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
Refined fundamental parameters of Canopus from combined near-IR interferometry and spectral energy distribution
A. Domiciano de Souza, J. Zorec, F. Millour +3
Canopus, the brightest and closest yellow supergiant to our Solar System, offers a unique laboratory for understanding the physics of evolved massive stars. The accurate and precis…
First MATISSE L-band observations of HD 179218. Is the inner 10 au region rich in carbon dust particles?
E. Kokoulina, A. Matter, B. Lopez +58
Carbon is one of the most abundant components in the Universe. While silicates have been the main focus of solid phase studies in protoplanetary discs (PPDs), little is known about…
I3T: Intensity Interferometry Imaging Telescope
Pierre-Marie Gori, Farrokh Vakili, Jean-Pierre Rivet +6
We propose a new approach, based on the Hanbury Brown and Twiss intensity interferometry, to transform a Cherenkov telescope to its equivalent optical telescope. We show that, base…
Extreme adaptive optics astrometry of R136. Searching for high proper motion stars
Zeinab Khorrami, M. Langlois, F. Vakili +9
We compared high-contrast near-infrared images of the core of R136 taken by VLT/SPHERE, in two epochs separated by 3.06 years. For the first time we monitored the dynamics of the d…
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…
High contrast and resolution near infrared photometry of the core of R136
Zeinab Khorrami, Maud Langlois, Paul C. Clark +8
We present the sharpest and deepest near infrared photometric analysis of the core of R136, a newly formed massive star cluster at the centre of the 30 Doradus star forming region…
