Pre-main Sequence Brackett Emitters in the APOGEE DR17 Catalog: Line Strengths and Physical Properties of Accretion Columns
Hunter Campbell, Elliott Khilfeh, Kevin R. Covey +21
Very young (t 10 Myrs) stars possess strong magnetic fields that channel ionized gas from the interiors of their circumstellar discs to the surface of the star. Upon imp…
Stellar population of the Rosette Nebula and NGC 2244: application of the probabilistic random forest
