the giants pipeline

---

an open-source Python package to search for exoplanets around evolved stars

This package is currently under development. Please reach out if you experience any issues.

• TESS Giants Transiting Giants. I. A Noninflated Hot Jupiter Orbiting a Massive Subgiant (Saunders et al. 2022)
• TESS Giants Transiting Giants. II. The Hottest Jupiters Orbiting Evolved Stars (Grunblatt et al. 2022)

To install the giants pipeline:

!git clone https://github.com/nksaunders/giants.git
!cd giants; pip install .

To produce a de-trended light curve and a transit-search summary plot:

import giants
target = giants.Target(ticid=176956893)
target.fetch_and_clean_data(sectors=[1,2])
target.create_summary_plot()

By default, this will query MAST and use all available sectors to produce a light curve (this can take a few minutes for some targets!). If you would like to specify which sectors to use, pass in a list of sectors numbers to the fetch_and_clean_data function, as shown above.

This will produce the following output:

You can also save the light curve for future use when producing the summary plot by passing in the save_data=True argument to create_summary_plot.
