Retrieval of atmospheric CO2 vertical profiles from ground-based near-infrared spectra [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
We evaluate vertical profile retrievals of CO2 from 0.02 cm−1 resolution ground-based near-infrared solar absorption spectra with the GFIT2 algorithm, using improved spectroscopic line lists and line shapes.

GOSAT-2014 methane spectral line list

open access: yesJournal of Quantitative Spectroscopy and Radiative Transfer, 2015
Abstract The updated methane spectral line list GOSAT-2014 for the 5550–6240 cm −1 region with the intensity cutoff of 5×10 –25  cm/molecule at 296 K is presented. The line list is based on the extensive measurements of the methane spectral line parameters performed at different temperatures and pressures of methane without and with buffer gases N 2

Temperature-dependent molecular absorption cross sections for exoplanets and other atmospheres [PDF]

open access: yes, 2012
Exoplanets, and in particular hot ones such as hot Jupiters, require a very significant quantities of molecular spectroscopic data to model radiative transport in their atmospheres or to interpret their spectra. This data is commonly provided in the form

The Optical Spectral Line List of RR Telescopii

open access: yesThe Astrophysical Journal Supplement Series, 1997
The symbiotic nova RR Telescopii has been observed with the 1.5 m telescope of the Cerro Tololo Inter-American Observatory (CTIO), using the 1.5 m bench-mounted echelle spectrograph in conjunction with a Tektronix CCD. It displays a rich emission-line spectrum, ranging in excitation from O I to [Ni VIII].

An upper limit for water dimer absorption in the 750 nm spectral region and a revised water line list [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Abstract. Absorption of solar radiation by water dimer molecules in the Earth's atmosphere has the potential to act as a positive feedback effect for climate change. There seems little doubt from the results of previous laboratory and theoretical studies that significant concentrations of the water dimer should be present in the atmosphere, yet ...

An improved ultraviolet spectral line list for the symbiotic star RR Telescopii

open access: yesThe Astrophysical Journal Supplement Series, 1993
We have remeasured wavelengths and intensities of International Ultraviolet Explorer (IUE) spectra of the symbiotic star, RR Tel. The main work is centered on the long 820 minute exposure high-resolution spectrum obtained on 1983 June 18. The list is intended to serve as a source of improved intensities and wavelengths for the ultraviolet spectrum of ...

ANALYSIS OF THE SPECTRAL ENERGY DISTRIBUTION OFTHE COOLEST RCrB TYPE CARBON STAR DY Per

open access: yesOdessa Astronomical Publications, 2008
We analysed the spectral energy distribution of the evolved carbon star DY Per by spectral synthesis technique. The red giant shows the photometric features of R CrB type stars.

An Updated Line List for NUV Spectral Synthesis in Evolved Stars: Redetermination of the Beryllium Abundance in the Solar Photosphere [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract Motivated by the desire to measure beryllium abundances in red giant stars, we have constructed a new line list for synthesizing spectra in the near-ultraviolet. Using the Sun, Arcturus, and Pollux as benchmark stars, we explore potential sources of missing continuous opacity and line absorption.
