Katie (Teixeira) Painter

I am a fourth-year astronomy graduate student at the University of Texas at Austin. I work with Prof. Brendan Bowler to search for and characterize exoplanets around nearby stars using various observational techniques, including astrometric accelerations, precision radial velocities, and high-contrast imaging. I am currently using these techniques to constrain the presence of giant planets around potential target stars for NASA's Habitable Worlds Observatory in order to prioritize which are likely to host stable Earth-sized planets in their habitable zones.

If you are interested in my work, please take a look at my CV and feel free to contact me.

Research Interests

I am generally interested in placing the Solar System in the context of other exoplanet systems in the Galaxy. I am interested in exploring what conditions are necessary for planets like Earth to exist.

Previous Work

In my previous research, I worked in atmospheric theory of rocky planets and exoplanet demographics using transit data. I focused on planets orbiting M dwarfs in my master's and undergraduate projects.

The Carbon-Deficient Evolution of Trappist-1c

Working with Prof. Caroline Morley in my master's, I designed a coupled, time-dependent simulation code to model the atmospheric evolution of small rocky planets around M dwarfs, well-suited to track the CO2 component of a Venus-like planet’s atmosphere. This code includes atmospheric escape and outgassing. I input data from JWST 15 μm MIRI observations of TRAPPIST-1c into my model to track the history of CO2 in its atmosphere.
