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 focal box offers increased capabilities for the ASTEP+ project. The opto-mechanical design of the camera was described in a previous paper.1 Here, we focus on the...

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 have periods of 56.0067 ± 0.0003 days and 84.2597 +0.0010-0.0008 days, which implies a period ratio very close to that of the first-order 3:2 mean motion resonance,...
