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…
