Hi there πŸ‘‹

I'm Adina. I'm an Assistant Professor in the Department of Physics and Astronomy at Michigan State University. My research aims to understand the interaction between baby stars and planets! In particular, I am using X-ray, UV, optical, and infrared observations of young stars and their planets to understand how planets evolve.

πŸ’Ύ Available Software Packages

  • nirHiss - a package for reducing and extracting JWST NIRISS/SOSS Time Series observations
  • stella - a convolutional neural network framework to detect stellar flares in time-series photometry
  • eleanor - a package for extracting high-precision light curves from NASA's Transiting Exoplanet Survey Satellite

πŸ“ Open-Source and Reproducible Manuscripts

  • Feinstein et al. (2025) - Precovery of 3I/ATLAS from TESS Suggests Possible Distant Activity.
  • Feinstein et al. (2024) - Evolution of Flare Activity in GKM Stars Younger Than 300 Myr over Five Years of TESS Observations.

πŸ”­ I’m currently working on

  • Characterizing stellar flares in the ultraviolet and infrared to understand their impacts on close-in exoplanets

πŸ’­ I'm currently thinking about

  • Using stellar flare rates as a new metric to constrain stellar ages
  • Breaking degeneracies in starspots from starspot crossing events
  • Disentangling chemical signatures of a star from planet
