I'm a PhD Student

  • Name: Adina D. Feinstein
  • Job: Graduate Student
  • Residence: United States
  • Hometown: Muttontown

Hi! I am a first year graduate student in the Astronomy & Astrophysics Department at the University of Chicago. I received my undergraduate degree in Astrophysics from Tufts University. Outside of academics, I have an addiction to baking, love crocheting, writing short stories, and sitting out by Lake Michigan. My work focuses on stellar and exoplanet astrophysics.

My Skills


Folded-port InfraRed Echellette (FIRE) Spectrograph

Magellan Telescope, Las Campanas Observatory

SpeX Spectrograph

NASA Infrared Telescope Facility

My Experience

  • Graduate Research Assistant

    Advisors: Benjamin Montet & Jacob Bean

    - Creating an open-source data analysis pipeline to produce light curves for roughly 25 million stars in the Transiting Exoplanet Survey Satellite (TESS) Full-Frame Images (FFIs)
    - Publicly available light curves are tailored towards finding exoplanet transits and will be hosted on the MAST serves at the Space Telescope Science Institute as High Level Science Products (HLSP)
    - Updates on the open-source pipeline can be found on my github: https://github.com/afeinstein20/eleanor

  • Undergraduate Research Assistant

    Advisor: Danilo Marchesini

    - Constructed catalogs of gravitational lensing magnifications using publicly available lensing models for Hubble Frontier Fields cluster pointins; Completed a statistical analysis of systematic and random errors; Catalogs can be found here: https://cosmos.phy.tufts.edu/~danilo/HFF/Home.html
    - Conducted a brief study on the evolution of high mass (log(M/M_Sun) >= 11) high redshift (2 < z < 6) galaxies using the Ultra Deep Survey with the VISTA telescope (UltraVISTA) Survey

  • Summer Research Assistant

    Advisor: Joshua Schlieder

    - Determined spectral types and ages of red dwarfs in the solar neighborhodd using SpeX, a medium resolution 0.7-5.3 micron spectrograph mounted on the NASA Infrared Telescope Facility
    - Calculated basic planet and stellar parameters from Kepler/K2 light curves and stellar spectra
    - Conducted planet confirmation follow-up analysis for a temperature 1.9 R_Earth planet identified by citizen scientists using the Exoplanet Explorers tool on the Zooniverse platform
