Using the motion of S2 to constrain vector clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +53

The dark compact object at the centre of the Milky Way is well established to be a supermassive black hole with mass , but the nature…

15NH3 in the atmosphere of a cool brown dwarf

David Barrado, Paul Mollière, Polychronis Patapis +40

Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identic…

The Chemical Inventory of the Inner Regions of Planet-forming Disks -- The JWST/MINDS Program

Inga Kamp, Thomas Henning, Aditya M. Arabhavi +40

The understanding of planet formation has changed recently, embracing the new idea of pebble accretion. This means that the influx of pebbles from the outer regions of planet-formi…
