Calculations of the Far‐Wing Line Profiles of Sodium and Potassium in the Atmospheres of Substellar‐Mass Objects

At the low temperatures achieved in cool brown dwarf and hot giant planet atmospheres, the less refractory neutral alkali metals assume an uncharacteristically prominent role in spectrum formation. In particular, the wings of the Na-D (5890 \AA) and K I (7700 \AA) resonance lines come to define the ... View More
