NAI Fellow Hannah Jang-Condell will leave DTM on 1 September for a Michelson Fellowship at the University of Maryland and NASA Goddard Space Flight Center. For the last three years, Jang-Condell has been studying planetary formation theory, focusing on disk-planet interactions. One of her main projects has been to model the effect of stellar heating on the surfaces of disks perturbed by forming planets. She has worked with Alan Boss’s disk instability models, in addition to creating her own models of planets forming by core accretion. From these models, Jang-Condell was able to predict observable signatures of planets forming in disks, and in particular, she determined how to distinguish between core accretion and disk instability. Jang-Condell has also worked to put limitations on the possibility of planet formation in close binary systems. She showed that a possible planet in the multiple-star system HD 188753 could not have formed in situ, and indeed, with follow-up observations of the system, the planet’s existence failed to be confirmed.
