About Courtney Dressing

I am a fourth-year graduate student in the Astronomy Department at Harvard University. My research interests include exoplanets, habitability, and astrobiology. I received a master's degree in astronomy and astrophysics from Harvard University and a bachelor's degree in astrophysical sciences from Princeton University. At Princeton, I worked with Jill Knapp to study the magnetic activity of M dwarfs with white dwarf companions and with Dave Spiegel to model the habitability of terrestrial exoplanets. For my senior thesis, I worked with Ed Turner, Michael McElwain, and the SEEDS (Strategic Explorations of Exoplanets and Disks with Subaru) collaboration to directly image young Jovian exoplanets using the Subaru telescope. At Harvard, I am working with Dave Charbonneau to study the properties, frequency, and detectability of small planets orbiting small stars.


  1. Possible clarification? If a 2 M_o star has a M/L ~ 0.16 and a 0.5 M_o has a M/L ~ 6.5, then a galaxy containing many more low mass stars (ie 0.5M_o stars) would have a HIGHER M/L than a galaxy with more high mass stars. The last sentence in the first paragraph of methods suggests otherwise.

    • That’s absolutely correct. Thank you very much for catching that typo!

  2. How are you?
    which is model useing to find M/L?
