  1. Parameter estimation in imaging Fabry-Perot Doppler spectroscopy

    Minin, SergeUniversity of Illinois at Urbana-Champaign2012

    Fabry-Perot spectroscopy has been used for many decades to observe optical phenomena in the Earth's upper atmosphere. The techniques have been evolving in recent years, with the major technical advancement being use of a CCD in the focal plane of the instrument. This dissertation rigorously …

  2. New techniques for sub-Doppler spectroscopy of molecular ions

    Siller, BrianUniversity of Illinois at Urbana-Champaign2013

    … new methods for performing high-resolution sub-Doppler spectroscopy of molecular ions in the laboratory. Molecular ions are of interest to a variety of fields, from astrochemistry to fundamental physics to the study of chemical reactive intermediates. The limiting factor in developing a deeper …

  3. High resolution Doppler spectroscopy of a transiting ultra-hot Jupiter at optical wavelengths

    Merritt, StephanieQueen's University Belfast2021

    … for characterisation through transmission spectroscopy. Recently, ultra-hot Jupiters (UHJs) have emerged as a distinct class of their own, with their huge dayside temperatures (over 22,00 K) driving entirely different chemistry than their cooler cousins, differing from that predicted by …

  6. Chemical physics and astrochemistry of H3+ and sub Doppler mid infrared spectroscopy of molecular ions

    Crabtree, Kyle N.University of Illinois at Urbana-Champaign2013

    … such insight can only be derived if laboratory spectroscopy of these ions has been performed. However, for many ionic species, insufficient laboratory data are available, and this is primarily because of difficulties in producing sufficient quantities of ions for traditional spectroscopic …

    Gandhi, Siddharth NandkumarUniversity of Cambridge2020

    … chemical detections using both high-resolution Doppler spectroscopy as well as low-resolution transit spectroscopy. I firstly computed the molecular and atomic cross sections of various species prevalent in the atmospheres of such exoplanets in order to compute their spectra. The absorption …
