Multi-band infrared imaging reveals dusty spiral arcs around the binary B[e] star 3 Puppis

M. Abello, J. Drevon, A. Meilland +24

3 Puppis is the brightest known B[e] star. Recent work classifies this A-type object as a supergiant, yet the impact of its binarity on the circumstellar environment (CE) remains h…

Observing exoplanets from Antarctica in two colours: Set-up and operation of ASTEP+

François-Xavier Schmider, Lyu Abe, Abdelkrim Agabi +12

On December 2021, a new camera box for two-colour simultaneous visible photometry was successfully installed on the ASTEP telescope at the Concordia station in Antarctica. The new…

The dusty circumstellar environment of Betelgeuse during the Great Dimming as seen by VLTI/MATISSE

E. Cannon, M. Montargès, A. de Koter +23

The 'Great Dimming' of the prototypical red supergiant Betelgeuse, which occurred between December 2019 and April 2020, gives us unprecedented insight into the processes occurring…

Locating dust and molecules in the inner circumstellar environment of R~Sculptoris with MATISSE

Julien Drevon, Florentin Millour, Pierre Cruzalèbes +49

AGB stars are one of the main sources of dust production in the Galaxy. However, it is not clear what this process looks like and where the dust is condensing in the circumstellar…

Observation Scheduling and Automatic Data Reduction for the Antarctic telescope, ASTEP+

Georgina Dransfield, Djamel Mekarnia, Amaury H. M. J. Triaud +13

The possibility to observe transiting exoplanets from Dome C in Antarctica provides immense benefits: stable weather conditions, limited atmospheric turbulence, and a night that la…

HD 28109 hosts a trio of transiting Neptunian planets including a near-resonant pair, confirmed by ASTEP from Antarctica

Georgina Dransfield, Amaury H. M. J. Triaud, Tristan Guillot +28

We report on the discovery and characterisation of three planets orbiting the F8 star HD~28109, which sits comfortably in \tess's continuous viewing zone. The two outer planets hav…
