Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars

Galaxies
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on the JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significantly from spectra obtained ∼16–19 years earlier with the Infrared ...

Near to Mid-infrared Spectroscopy of (65803) Didymos as Observed by JWST: Characterization Observations Supporting the Double Asteroid Redirection Test

The Planetary Science Journal, 2023
The Didymos binary asteroid was the target of the Double Asteroid Redirection Test (DART) mission, which intentionally impacted Dimorphos, the smaller member of the binary system.

Review of Spitzer Space Telescope observations of small bodies [PDF]

Proceedings of the International Astronomical Union, 2005
The Spitzer Space Telescope (SST), aloft for over two years at time of writing, has so far devoted almost 600 hours of observing time to Solar System science, and small bodies make up a significant fraction of the objects that have been observed. For the first time we now have high accuracy mid-infrared data to study the fundamental mineralogical and

First images from a Warm Spitzer

, 2016
These are the first images of the Warm Spitzer mission, which mark a new phase of the telescope that operates more than five years. The photos were captured with two infrared channels working at a temperature of about 30 Kelvin.

Large Cold Dust Reservoir Revealed in Transitional SN Ib 2014C by James Webb Space Telescope Mid-infrared Spectroscopy

The Astrophysical Journal
Supernova (SN) 2014C is a rare transitional event that exploded as a hydrogen-poor, helium-rich Type Ib SN and subsequently interacted with a hydrogen-rich circumstellar medium (CSM) a few months postexplosion.

The Supernova Legacy of Spitzer Space Telescope

, 2019
The mid-infrared (mid-IR) range offers an obvious and advantageous choice in following the late-time evolution of supernovae (SNe). First, the peaks of their spectral energy distributions (SED) shift toward the IR after the photospheric phase; second, mid-IR observations are practically free of interstellar extinction, which is also an important factor

Prominent Mid-infrared Excess of the Dwarf Planet (136472) Makemake Discovered by JWST/MIRI Indicates Ongoing Activity

The Astrophysical Journal Letters
We report on the discovery of a very prominent mid-infrared (18–25 μ m) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the Mid-Infrared Instrument of the James Webb Space Telescope, along with previous ...
