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 "decadesof innovative studiesof the heliosphere and the local interstellarmedium; for his models of stellar chromospheres, for productiveobserving programs on multiple satellites and for establishing the deuterium-to-hydrogen ratioin 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!
Astrophysicist Jeff Linsky and his colleagues recently created a sophisticated mathematical model of the outer atmosphere of the small M-dwarf star called GJ832. The new model fits well with spectral observations of the star made with the Hubble Space Telescope (HST). This accomplishment bodes well for two reasons: First, it provides a tool for better understanding M-dwarf stars––the most common type of star in our galaxy.
