“Inside the Snowline: What Infrared Spectra Reveal About Disks Around Young TRAPPIST-1-like Stars”

Small rocky planets are abundant around late M-type stars and many of them are now key targets for atmospheric characterization with JWST. Are these planets similar or different than those around Sun-like stars? I will present infrared spectroscopy of disks around young TRAPPIST-1 analogues spanning ages from a few to tens of millions of years. These spectra show that the gas inside the snowline commonly exhibits elevated C/O ratios. I will discuss models capable of reproducing these observations and explore the implications for the composition and atmospheres of planets forming in these environments.

Planetary Lunch Seminar —

Colloquia topics span the range of research interests of the department’s planetary sciences research program, and the talks are intended to appeal to any graduate students, postdocs, research scientists, and faculty with a background in planetary science. Speakers include members of the MIT community and visitors.
