Prachi Chavan

I’m a PhD student working in planetary sciences with Bin Yang and Lucas Cieza. My research goal is to analyze the observations of protoplanetary disks and Solar System objects contributing to our understanding of planetary system formation and celestial body evolution.

Current position: PhD student


  1. I am doing a multi-frequency analysis of protoplanetary discs (PPDs) in the Ophiuchus star-forming region from ALMA observations focusing on constraining dust properties and test dust evolution models. These findings will provide important insights into early planet formation processes and contribute essential benchmark information for interpreting disk studies at different wavelengths.
  2. I’m also working on Pallas family of asteroids using near-infrared spectroscopy that aims to explore the unique characteristics of this family, including blue spectral slopes, high inclination, and composition. By studying their nature and origins, we gain valuable insights into the early Solar System and the evolution of celestial bodies.
  3. I plan to do cometary dust observations in future to investigate the particle size distribution and mineral composition providing valuable insights into the processes that shaped our Solar System considering they are the oldest and least altered objects.
