The Spitzer Atlas of Stellar Spectra
The Spitzer Atlas Stellar Spectra
font style='font-size:12px;'>
2011/1/11
We present the Spitzer Atlas of Stellar Spectra (SASS), which includes 159 stellar spectra (5 to 32 mic; R~100) taken with the Infrared Spectrograph on the Spitzer Space Telescope. This Atlas gathers ...
Warm Spitzer Photometry of the Transiting Exoplanets CoRoT-1 and CoRoT-2 at Secondary Eclipse

2010/11/10
We measure secondary eclipses of the hot giant exoplanets CoRoT-1 at 3.6 and 4.5 μm, and CoRoT-2 at 3.6 μm, both using Warm Spitzer. We find that the Warm Spitzer mission is working very well for exop...
Galactic Cepheids with Spitzer: II. Search for Extended Infrared Emission
Cepheids — infrared stars — stars mass loss

2010/11/16
A deep and detailed examination of 29 classical Cepheids with the Spitzer Space Telescope has revealed three stars with strong nearby extended emission detected in multiple bands which appears to be p...
Spitzer observations of supernova remnants: II. Physical conditions and comparison with HH7 and HH54
molecular — ISM abundance — ISM clouds molecular processes shock waves
font style='font-size:12px;'>
2010/11/9
We have studied the shock-excited molecular regions associated with four supernova remnants (SNRs) — IC443C, W28, W44 and 3C391 — and two Herbig-Haro objects,HH7 and HH54, using Spitzer ’s Infrared Sp...
The Supernova Impostor Impostor SN 1961V: Spitzer Shows That Zwicky Was Right (Again)
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2011/1/7
SN 1961V, one of Zwicky's defining Type V supernovae (SN), was a peculiar transient in NGC 1058 that has variously been categorized as either a true core collapse SN leaving a black hole (BH) or neutr...
A Spitzer IRS Study of Debris Disks Around Planet-Host Stars
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP)
font style='font-size:12px;'>
2011/1/6
Since giant planets scatter planetesimals within a few tidal radii of their orbits, the locations of existing planetesimal belts indicate regions where giant planet formation failed in bygone protoste...
Dust in the diffuse emission of the galactic plane - The Herschel/Spitzer SED fitting
Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2011/1/4
The first Herschel Hi-Gal images of the galactic plane unveil the far-infrared diffuse emission of the interstellar medium with an unprecedented angular resolution and sensitivity. In this paper, we p...
Nearby early-type galaxies with ionized gas VI. The Spitzer-IRS view
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/29
We present low resolution Spitzer-IRS spectra of 40 ETGs, selected from a sample of 65 ETGs showing emission lines in their optical spectra. We homogeneously extract the mid-infrared (MIR) spectra, an...
Spitzer IRS 16 micron Observations of the GOODS Fields
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/28
We present Spitzer 16 micron imaging of the Great Observatories Origins Deep Survey (GOODS) fields. We survey 150 square arcminutes in each of the two GOODS fields (North and South), to an average 3 s...

font style='font-size:12px;'>
2010/12/28
Gamma-ray burst (GRB) host galaxies have been studied extensively in optical photometry and spectroscopy. Here we present the first mid-infrared spectrum of a GRB host, HG031203. It is one of the near...
