A semi-analytical surrogate model for giant planet evolution: bypassing ordinary differential equation solvers with localised thermodynamics, softplus asymptotes, and B-spline photometry
Christian Wilkinson, Jonas Wehrung-Montpezat, Benjamin Charnay +7
Context. Evolutionary models translate the observable luminosity, temperature, and colours of giant planets and brown dwarfs into mass and age. Generating their cooling tracks norm…

Deep high-resolution L band spectroscopy in the Pictoris planetary system
Markus Janson, Jonas Wehrung-Montpezat, Ansgar Wehrhahn +4
The beta Pictoris system, with its two directly imaged planets beta Pic b and beta Pic c and its well characterised debris disk, is a prime target for detailed characterisation of…
