SPITZER SPACE TELESCOPE MID-IR LIGHT CURVES OF NEPTUNE [PDF]

open access: yesThe Astronomical Journal, 2016
ABSTRACT We have used the Spitzer Space Telescope in 2016 February to obtain high cadence, high signal-to-noise, 17 hr duration light curves of Neptune at 3.6 and 4.5 μm. The light curve duration was chosen to correspond to the rotation period of Neptune.

Y Dwarf Trigonometric Parallaxes from the Spitzer Space Telescope [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract Y dwarfs provide a unique opportunity to study free-floating objects with masses <30 M Jup and atmospheric temperatures approaching those of known Jupiter-like exoplanets. Obtaining distances to these objects is an essential step toward characterizing their absolute physical properties.

Obscured and Unobscured Active Galactic Nuclei in the Spitzer Space Telescope First Look Survey [PDF]

open access: green, 2004
Selection of active galactic nuclei (AGNs) in the infrared facilitates the discovery of AGNs whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess the fraction of AGNs with mid-

In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope [PDF]

open access: greenSPIE Astronomical Telescopes + Instrumentation, 2004
The Infrared Array Camera (IRAC) is one of three focal plane instruments on board the Spitzer Space Telescope. IRAC is a four-channel camera that obtains simultaneous broad-band images at 3.6, 4.5, 5.8, and 8.0 μm in two nearly adjacent fields of view ...

Spitzer Space Telescope Observations of Low Mass X-ray Binaries [PDF]

open access: green, 2008
We present preliminary results from our archival Spitzer Space Telescope program aimed at characterizing the mid-IR properties of compact objects, both isolated and in binary systems, i.e.

Spitzer Space Telescope Infrared Observations of the Binary Neutron Star Merger GW170817 [PDF]

open access: yesAstrophysical Journal, 2018
We present Spitzer Space Telescope 3.6 and 4.5 micron observations of the binary neutron star merger GW170817 at 43, 74, and 264 days post-merger. Using the final observation as a template, we uncover a source at the position of GW170817 at 4.5 micron ...

Absolute Flux Calibration of the IRAC Instrument on the Spitzer Space Telescope using Hubble Space Telescope Flux Standards [PDF]

open access: bronze, 2011
The absolute flux calibration of the James Webb Space Telescope will be based on a set of stars observed by the Hubble and Spitzer Space Telescopes. In order to cross-calibrate the two facilities, several A, G, and white dwarf (WD) stars are observed ...

A Survey for New Members of Taurus with theSpitzer Space Telescope [PDF]

open access: yesThe Astrophysical Journal, 2006
We present the results of a search for new members of the Taurus star-forming region using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope}. With IRAC images of 29.7 deg^2 of Taurus at 3.6, 4.5, 5.8, and 8.0 um, we have identified sources with red mid-infrared colors indicative of disk-bearing objects and have obtained optical and ...

Mid‐Infrared Spectra of Classical AGNs Observed with theSpitzer Space Telescope [PDF]

open access: bronze, 2005
Full low-resolution (65 < R < 130) and high-resolution (R ~ 600) spectra between 5 and 37 μm obtained with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope are presented for eight classical active galactic nuclei (AGNs) that have been ...
