Infrared photometry of UV Piscium

open access: yesAstrophysics and Space Science, 1987
The eclipsing binary system UV Psc was observed in the near-infrared (JHK), and a wave-like distortions have been observed similar to those in the visible. The out-of-eclipse observations have shown real large amount of scatter. This cannot be attributed to the existence of spots on one of the components, which can explain the wave-like distorition of ...

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

open access: yesThe 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 ...

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

open access: yesThe 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 ...

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

open access: yesThe 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

Estimating the luminosities of protostars with limited infrared photometry

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT The luminosities of protostars provide one of the only indirect methods of measuring their masses and mass accretion rates in their earliest stages of evolution. Accurate measurements of protostellar luminosities traditionally requires assembling complete spectral energy distributions (SEDs) from the near-infrared through ...

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

open access: yes, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Infrared photometry and polarimetry of blazars [PDF]

open access: yes, 1985
A sample of blazars has been studied with infrared photometry and polarimetry in the J,H & K wavebands, using the U.K.I.R.T. in Hawaii. The objects observed for this thesis are part of an ongoing monitoring programme, for which a total of 35 objects ...

Spitzer Photometry of WISE-Selected Brown Dwarf and Hyper-Lumninous Infrared Galaxy Candidates

open access: yes, 2012
We present Spitzer 3.6 and 4.5 micrometer photometry and positions for a sample of 1510 brown dwarf candidates identified by the Wide-field Infrared Survey Explorer (WISE) all-sky survey.

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

open access: yesThe 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.
