Water is predicted to be among the most abundant (if not the most abundant) molecular species after hydrogen in the atmospheres of close-in extrasolar giant planets ('hot Jupiters'). Several attempts have been made to detect water on such planets, but have either failed to find compelling evidence for it or led to claims that should be taken with caution.(More)
The Infrared Array Camera (IRAC) is one of three focal plane instruments on the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broadband images at 3.6, 4.5, 5.8, and 8.0 m. Two nearly adjacent 5A2 ; 5A2 fields of view in the focal plane are viewed by the four channels in pairs (3.6 and 5.8 m; 4.5 and 8 m). All four detector(More)

We have conducted a photometric monitoring program of 3 field late-L brown dwarfs (DENIS-P J0255-4700, 2MASS J0908+5032 and 2MASS J2244+2043) looking for evidence of non-axisymmetric structure or temporal variability in their photospheres. The observations were performed using Spitzer/IRAC 4.5 µm and 8 µm bandpasses and were designed to cover at least one(More)
We investigate the density structure of the interstellar medium using new high-resolution maps of the 8 µm, 24 µm, and 70 µm surface brightness towards a molecular cloud in the Gum Nebula, made as part of the Spitzer Space Telescope Galactic First Look Survey. The maps are correlated with 100 µm images measured with IRAS. At 24 and 70 µm, the spatial power(More)
Hi-GAL, the Herschel infrared Galactic Plane Survey, is an Open Time Key Project of the Herschel Space Observatory. It will make an unbiased photometric survey of the inner Galactic Plane by mapping a two-degree wide strip in the longitude range | l |< 60 • in five wavebands between 70µm and 500µm. The aim of Hi-GAL is to detect the earliest phases of the(More)
Context. The evolution of a young protocluster depends on the relative spatial distribution and dynamics of both stars and gas. Aims. We study the distribution and properties of the gas and stars surrounding the luminous (10 4 L⊙) protocluster IRAS 18511+0146. Methods. IRAS 18511+0146 and the cluster associated with it has been investigated using the(More)
