| Abstract I will present a few relevant topics for upcoming Chinese-Chilean collaborations. Including, (1) A quick overview of the current state of the state of Chilean Astronomy, (2) a first attempt at East Antarctica site testing for Astronomy, and (3) the first detection of Calcium in an exoplanetary atmosphere. The latter was product of a new pipeline that performs an automated search for the exoatmospheric presence of several elements without any a-priori assumptions on its existence or strength. We analyzed thousands of lines in the full spectral range of this optical echelle spectrograph using a robust method to correct for the telluric contamination. We recover previous detections of Sodium and Halpha, and present the first strong detection of Calcium in an Extrasolar Atmosphere as well as the tentative detection of other elements. The Calcium detection is in disagreement with theoretical thermal-equilibrium models. |
