Very Large Telescope three micron spectra of dust-enshrouded red giants in the Large Magellanic Cloud

Jacco Th. van Loon, Jonathan R. Marshall, Martin Cohen +4

We present ESO/VLT spectra in the 2.9--4.1 micron range for a large sample of infrared stars in the Large Magellanic Cloud (LMC), selected on the basis of MSX and 2MASS colours to…

Biosignatures from Earth-Like Planets Around M Dwarfs

Antigona Segura, James F. Kasting, Victoria Meadows +5

Coupled one-dimensional photochemical-climate calculations have been performed for hypothetical Earth-like planets around M dwarfs. Visible, near-infrared and thermal-infrared synt…

"PAH" emission bands in selected planetary nebulae: a study of the behaviour with gas phase C/O ratio

Martin Cohen, Michael J. Barlow

Airborne and space-based low-resolution spectroscopy in the 1980s discovered tantalizing quantitative relationships between the gas phase C/O abundance ratio in planetary nebulae (…

Absolute Calibration of the Infrared Array Camera on the Spitzer Space Telescope

William T. Reach, S. T. Megeath, Martin Cohen +10

The Infrared Array Camera (IRAC) on the Spitzer Space Telescope is absolutely calibrated by comparing photometry on a set of A stars near the north ecliptic pole to predictions bas…

Formation and Evolution of Planetary Systems: Cold Outer Disks Associated with Sun-like stars

Jinyoung Serena Kim, Dean C. Hines, Dana E. Backman +24

We present the discovery of debris systems around three solar mass stars based upon observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, ``t…
