OVERVIEW

INTRODUCTION
The Smithsonian Astrophysical Observatory (SAO) is at the forefront, internationally, of the scientific exploration of the universe. SAO combines its resources with those of the Harvard College Observatory to form the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA is the best-known astrophysics center in the world. Its programs range from ground-based astronomy and astrophysics research to space-based research, the engineering and development of major scientific instrumentation for space launch and use in large ground-based facilities, and research designed to improve science education. The research objectives of SAO are carried out primarily with the support of Government and Smithsonian Institution funds, with additional philanthropic support. Government funds are in the form of Federal appropriations or the form of contracts and grants from other agencies. In contrast, Institution funds are available to SAO through grants from the Institution's Restricted Funds, Special Purpose Funds, Bureau Activities, Business Activities, and non-Federal contracts and grants.

SUMMARY
This is the position of Astronomer, Optical and Infrared Astronomy Division, Smithsonian Astrophysical Observatory (SAO). The primary purpose of this position is to confirm and characterize systems with transiting planet candidates identified by NASA’s Transiting Exoplanet Survey Satellite (TESS). The work will involve extensive analysis of photometric and spectroscopic observations of TESS Objects of interest (TOIs) and preparation of the results for publication in papers and presentations at meetings. The incumbent will also formulate and conduct original programs of independent astronomical research, with an emphasis on studies of exoplanets.

MAJOR DUTIES

• Duties listed are at a Full Performance Level IS-11.
• Participate in the Transiting Exoplanet Survey Satellite (TESS)--a NASA Explorer Class mission- -as a member of the TESS Science Office at SAO, with a focus on the work of the TESS Followup Observing Program Working Group (TFOPWG) in confirming and characterizing transiting planet candidates identified by the mission. Identifies Targets of Interest (TOIs) that are promising potential targets for transit spectroscopy with space missions such as ARIEL and JWST.
• Perform and interpret advanced data reduction, statistical analysis, and modeling using specialized astronomical software, in particular EXOFAST
• Prepare technical reports, peer-reviewed manuscripts, conference abstracts, and presentations summarizing research findings.
• Conduct combined analyses of the spectroscopic and photometric results to derive masses and radii for TOI host stars and their low-mass companions using a tool such as EXOFASTv2. Updates the ephemeris for transit events to support follow-up observations such as transit spectroscopy with the above space missions.
• Performs related duties as assigned.
