Identifying and Characterizing Infrared Excesses in the Spitzer Kepler Survey (SpiKeS)

The Astrophysical Journal
We report our search for infrared excesses in the Spitzer/Infrared Array Camera survey of the Kepler field at 3.6 and 4.5 μ m. The Spitzer Kepler Survey contains ∼190,000 targets, which we reduce to ∼117,000 targets after applying multiple filters to ...

Infrared photometry of the 1982-4 eclipse of Epsilon Aurigae [PDF]

, 1985
The infrared photometry of epsilon Aur performed prior to and during the ingress phase of the recent eclipse allowed the first solid determination of the temperature of the secondary object.

Photometric Mapping of Carbonaceous/Siliceous Dust and Water Ice in the ISM with JWST: Applications to the Dense Sightlines

The Astronomical Journal
We introduce a new photometric mapping method for the James Webb Space Telescope (JWST) to measure the spatial distribution of carbonaceous dust, siliceous dust, and water ice by using absorption features arising from the grains in the dense interstellar

Two Methods of Near Infrared Reflectance Spectroscopy for Determining the Digestibility and Energy Value of Feeds [PDF]

, 1997
Two groups of rations with known in vivo digestibility and energy values were used in this study. These rations were composed of Italian ryegrass only (lRO. n = 45), and combination of Italian ryegrass and concentrates (lRC, n = 58).

The Baryonic Tully–Fisher Relation. I. WISE/Spitzer Photometry

The Astronomical Journal
We present Wide-field Infrared Survey Explorer (WISE) W1 photometry of the Spitzer Photometry and Accurate Rotation Curves sample. The baseline of near-IR fluxes is established for use by stellar mass models, a key component to the baryonic Tully–Fisher ...

Infrared photometry of the nuclei of early-type radio galaxies

, 1986
The authors have obtained near- and mid-infrared photometry of the nuclei of both strong and weak radio galaxies. The implication of these data are that a relatively small percentage, ≅15 per cent, of radio ellipticals have strong infrared emission ...

A Highly Magnetic Ultramassive White Dwarf with a 23 minute Rotation Period

The Astrophysical Journal
We present a physical characterization of Tsinghua University-Ma Huateng Telescope for Survey (TMTS) J00063798+3104160 (J0006), a rapidly rotating, ultramassive white dwarf (WD) identified in high-cadence light curves from the TMTS.

The Lunar Opposition Effect: Dual-mechanism Partitioning and Shallow-regolith Constraints from GaoFen-4 Photometry

The Planetary Science Journal
The lunar opposition effect (OE) probes shallow regolith structure and multiple-scattering behavior, but its physical interpretation is limited by difficulties separating shadow-hiding (SHOE) and coherent-backscatter (CBOE) components and comparing ...
