Exoplanet Proxima b will be an important laboratory for the search for extraterrestrial life for the decades ahead. Here we discuss the prospects of detecting carbon dioxide at 15 um using a spectral filtering technique with the Medium Resolution Spe

Ground-based near-infrared observations of water vapour in the Venus troposphere

Autor: Chamberlain, S., Bailey, J. A., Crisp, D., Meadows, V. S.

We present a study of water vapour in the Venus troposphere obtained by modelling specific water vapour absorption bands within the 1.18 \mu m window. We compare the results with the normal technique of obtaining the abundance by matching the peak of

The Near-IR Spectrum of Titan Modeled with an Improved Methane Line List

Autor: Bailey, Jeremy, Ahlsved, Linda, Meadows, V. S.

We have obtained spatially resolved spectra of Titan in the near-infrared J, H and K bands at a resolving power of ~5000 using the near-infrared integral field spectrometer (NIFS) on the Gemini North 8m telescope. Using recent data from the Cassini/H

Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmospheres and surfaces with spectroscopy. Rocky planets within their sta

Abiotic formation of O2 and O3 in high-CO2 terrestrial atmospheres

Autor: Segura, A., Meadows, V. S., Kasting, J. F., Crisp, D., Cohen, M.

Publikováno v: Astron.Astrophys.472:665-679,2007

Previous research has indicated that high amounts of ozone (O3) and oxygen (O2) may be produced abiotically in atmospheres with high concentrations of CO2. The abiotic production of these two gases, which are also characteristic of photosynthetic lif
