Quantifying Physical Properties of Starspots #1

Hello, I'm a student from UT joining this project for summer 2022. To answer the above question, here are some tasks I'll need to accomplish:

As a reminder, here is the abstract for this project:

Exoplanet atmospheres research has grown immensely in the last 5 years, owing to the success of transit spectroscopy. A major barrier remains. Stellar contamination from unocculted starspots (and faculae) produces wavelength-dependent transit depths that mimic genuine exoplanet signals. The problem is especially acute in young, heavily spotted stars. In this IGRINS 2021A program, we will quantify the total starspot coverage fraction for a sample of ~15-25 young (5-300 Myr) GKM stars. We will use probabilistic spectral decomposition (Gully-Santiago et al. 2017) to measure the starspot temperature contrast and areal filling factor, the key metrics controlling stellar contamination. Contemporaneous TESS lightcurves will inform the phase of rotational modulation and constrain longitudinal surface structure symmetries.

Ok I added a README.md file in the acdc/data/IGRINS/ directory. It has a link to a UTBox folder, and instructions to follow in order to unzip the file into the right place.

Ok, I added the $\LaTeX$ templates in the path acdc/paper/paper1/

In order to generate the pdf, simply type:

make

from a terminal in the acdc/paper/paper1/ directory.
