Context: A new generation of instruments (e.g., JWST, ELTs, PLATO, Ariel) is providing atmospheric spectra and mass/radius measurements for large exoplanet populations, challenging planetary models used to interpret these findings. Aims: We develop a new model, the Heat Atmosphere Density Evolution Solver (HADES), by coupling an atmosphere and...

Recent observations by the B-star Exoplanet Abundance Study (BEAST) illustrate the existence of substellar companions around very massive stars. Here, we present the detection of two lower mass companions to a relatively nearby (148.7 −1.3 +1.5 pc), young (17 −4 +3 Myr), bright ( V = 6.632 ± 0.006 mag), 2.58 ± 0.06 M ⊙ B9V star HIP 81208...
