JILA Fellow Adjoint and the University of Colorado Boulder professor Dr. Jeffrey Linksy has been selected as a Fellow for the American Astronomical Society (AAS). Linksy was cited for "decades of innovative studies of the heliosphere and the local interstellar medium; for his models of stellar chromospheres, for productive observing programs on multiple satellites and for establishing the deuterium-to-hydrogen ratio in the local disk, among other scientific contributions, and for his decades of service to the astronomical community.” At JILA, Linksy's research involves the analysis of high-resolution stellar spectra, primarily in the ultraviolet, to measure the physical properties of stars, the atmospheres of exoplanets, gas in the local interstellar medium, and the abundance of deuterium in the Galaxy. Congratulations Dr. Linksy!
