  1. 2235. Observing the Dynamics of the Martian Atmosphere (I)
    William Ward (University of New Brunswick)

    Invited Speaker / Conférencier(ère) invité(e)

    The Martian atmosphere exhibits more dynamical variability than the terrestrial atmosphere with large amplitude tides and gravity waves in addition to the seasonal dust storms. To date, there have not been dedicated wind measurements from orbit around Mars and there is some evidence that the winds do not match expectations from models. As with the terrestrial atmosphere, airglow is one means...

  2. 2180. WaMI: The Waves Michelson Interferometer (G)*
    Samuel Kristoffersen
    12/06/2018, 16:00
    Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    The Waves Michelson Interferometer (WaMI) is designed to make wind measurements of the atomic oxygen green line (557.7 nm) emission, a molecular oxygen line at 1264 nm, and a hydroxyl line at 1315 nm. These emissions provide a capability for probing the dynamics of the middle atmospheres of the terrestrial planets. The special feature of the design of this instrument is that the back mirror is...

  3. 1989. Search for Vertical Stratification of Element Abundances in Chemically Peculiar stars
    Prof. Viktor Khalack (Université de Moncton)
    12/06/2018, 16:15
    Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)
    Oral (Non-Student) / Orale (non-étudiant(e))

    A portion of upper main-sequence stars, called chemically peculiar (CP) stars, show significant abundance anomalies mainly due to atomic diffusion of chemical elements within the stellar atmospheres of these stars. Slowly rotating CP stars may have hydrodynamically stable atmospheres where a competition between the gravitational and radiative forces launches the mechanism of atomic diffusion...

  4. 2085. Search for Vertical Abundance Stratification of Chemical Elements in HD176232 (U)*
    Mathieu Perron-Cormier (Université de Moncton)
    12/06/2018, 16:30
    Atmospheric and Space Physics / Physique atmosphérique et de l'espace (DASP-DPAE)
    Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

    Two high resolution and high signal to noise ratio spectra of HD176232 have been analyzed to study the chemical abundances in atmosphere of this star using the ZEEMAN2 code. These spectra were recently obtained with the spectropolarimeter ESPaDOnS at the Canada-France-Hawaii telescope (CFHT) in the frame of the project VeSElkA. The project’s objective is the search for signatures of vertical...
