Detection of methane in the martian atmosphere: evidence for life?
Using the Fourier Transform Spectrometer at the Canada–France–Hawaii Telescope, we observed a spectrum of Mars at the P-branch of the strongest CH4 band at 3.3 µm with resolving power of 180,000 for
Deuterium on Mars: The Abundance of HDO and the Value of D/H
The enrichment of deuterium on Mars implies that hydrogen escaped more rapidly from Mars in the past than it does now, consistent with a dense and warm ancient atmosphere on the planet.
Carbon Monoxide on Jupiter: Evidence for Both Internal and External Sources
Abstract Thirteen lines of the CO band near 4.7 μm have been observed on a jovian hot spot at a resolution of 0.045 cm−1. The measured line profiles indicate that the CO mole fraction is 1.0±0.2 ppb
The nature of the Galactic Center source IRS 13 revealed by high spatial resolution in the infrared
High spatial resolution observations in the 1 to 3.5 μm region of the Galactic Center source known historically as IRS 13 are presented. They include ground-based adaptive optics images in the H, Kp
Hot and cold gas toward young stellar objects
High-resolution M band spectra are presented for the seven embedded IR sources W3 IRS 5, S140 IRS1, NGC 7538 IRS 1, NGC 7538 IRS 9, GL 2136, LkH-alpha 101, and MWC 349A, and the data are combined
Kinematic and structural analysis of the Minispiral in the Galactic Center from BEAR spectro-imagery
Integral field spectroscopy of the inner region of the Galactic Center, over a field of roughly 40 �� ×40 �� was obtained at 2.06 µ m( He) and 2.16 µ m( Brγ) using BEAR, an imaging Fourier Transform
Ground‐based near‐infrared observations of the Venus nightside: 1.27‐μm O2(a 1Δ g ) airglow from the upper atmosphere
Near-infrared spectroscopic observations of Venus taken in 1975 revealed O2(a1Δg) airglow from both the dayside and nightside of the planet with emission rates exceeding 1 mega-Rayleigh (1 MR = 1012
New results on the helium stars in the galactic center using BEAR spectro-imagery
Integral eld spectroscopy of the central parsec of the Galactic Center was obtained at 2.06 mu sing BEAR, an imaging Fourier Transform Spectrometer, at a spectral resolution of 74 km s 1 . Sixteen
Detection of diffuse interstellar bands in the infrared
THE diffuse interstellar bands (DIBs) are spectral absorption features caused by interstellar matter but not identified with any known atomic or molecular lines. Since 1975, when 39 such bands were
High resolution near-infrared spectro-imaging of NGC 7027
We present near-infrared spectro-imaging of the young planetary nebula NGC 7027 between 2.10 and 2.20  μ m with high spatial (0.5″) and high spectral ($\rm 8.7 \, km \, s^{-1}$) resolution. The
