The primary purpose of the position is to contribute to the confirmation and characterization of transiting planet candidates identified by NASA’s Transiting Exoplanet Survey Satellite (TESS). At the developmental trainee level, assignments combine the performance of productive work with orientation and supervised on-the-job training in areas such as computer programming, developing and analyzing algorithms, data reduction and analysis, and documenting and organizing results.

Assignments are expected to allow the trainee to carry out progressively more difficult and responsible tasks.

Duties:

  1. Participate in coordinating observations by TFOP Sub Group 1 (seeing limited light curve follow-up). This will involve a review of new photometric observations daily as they are uploaded to ExoFOP and recommending any changes needed to the observing priorities and planet candidate It may also involve regular scheduling and review of observations from the Las Cumbres Observatory (LCO) and other SAO-affiliated observatories. It will also involve searches of ExoFOP, the SG1 tracking spreadsheet, and the literature for previous follow-up light curve results.
  2. Participate in the data reduction of LCO photometric observations. This will involve the analysis of LCO images to extract precise time-series differential photometric data using software tools such as AstroImageJ, uploading results to ExoFOP, and submitting them to the TFOP SG1 team.
  3. Participate in maintaining the TFOP SG1 TOI List Google spreadsheet. This will involve updating dispositions, observing priorities, and TOI parameters on the SG1 TOI list. These updates will be from the joint analysis of available TESS data validation reports, TESS FFI data, and TFOP SG1 follow-up light It will also involve updating the SG1 TOI List with new TOI releases.
  4. Support publication of the TFOP SG1 results. This will involve a joint assessment of all available SG1 data for potential inclusion in the joint modeling of the planetary system, communicating with lead and other key authors, and writing the supporting SG1 observations descriptions using LaTeX (typically on Overleaf).
  5. Write, modify, test, maintain, and document software as needed to support the above duties. Identify needs for improved procedures and software and participate in implementation and Modify existing codes in response to approved needs. Write well-organized and maintainable new code as required to support the above duties. Document code and any modifications.
  6. Perform other related duties as assigned.
