Vignesh is interested in understanding the formation and evolution of atmospheres in small, young exoplanets. He obtained his doctoral degree for his ground-based transit observational work with Dr. Bunei Sato and Dr. Teruyuki Hirano from Tokyo Institute of Technology, Japan in 2021. He continued his work on high-resolution spectroscopic analysis of small exoplanets (IRD/Subaru Telescope) in National Astronomical Observatory of Japan (NAOJ, Mitaka) in Tokyo until September 2022. He moved to McGill University in November 2022 to continue probing the atmospheres of exoplanets through the newly installed Near Infra-Red Planet Searcher (NIRPS) spectrograph on the ESO 3.6-m telescope.
Vignesh also focuses his attention on the novel methods to correct telluric lines in the near infrared (NIR) spectra. This would help astronomers to robustly remove the telluric lines in their spectra. His research would provide an extensive picture on the formation and evolution of exoplanet atmospheres.
