About Me

Hi, I am Shih-Yun Tang 湯士昀, a graduate student from Taiwan studying at the Northern Arizona University (NAU) Department of Astronomy and Planetary Science. I am working with Dr. Lisa Prato at the Lowell Observatory on using NIR and optical spectra to search for the youngest exoplanets around T Tauri stars. Meanwhile, I am also working with Prof. Tyler Robinson at NAU to model ultracool objects’ atmosphere using the 1D radiative-convective model. Lastly, as my side project, I am also working with Prof. Xiaoying Pang on using Gaia data to study stellar groups in the solar neighborhood.

I completed my B.A. and M.S. in Physics at the National Central University (NCU), Taiwan. My first research project was to characterize the stellar and substellar members in the Coma Berenices star cluster with Prof. Wen-Ping Chen as an undergraduate. Later, as my Master's thesis, I was among the first to discover the tidal tails of the Coma Berenices star cluster.
