Near-infrared photometry and optical spectroscopy of IRAS sources in the Small Magellanic Cloud

, 1997
Near-infrared photometry is obtained of 30 IRAS sources in the direction of the Small Magellanic Cloud selected to be possible AGB stars. Low resolution 4000 to 10 000 A spectroscopy is presented for 10 of them, plus two AGB stars in the LMC.

Taxonomic Classification of Asteroids via Broadband Near-Infrared Photometry

, 2010
For faint asteroids, it is not practical to obtain near-infrared spectra. However, it may be possible to use broadband photometry to infer spectral classifications and study composition.

Infrared photometry of UV Piscium

Astrophysics 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 ...

From Earths to Super-Earths: Five New Small Planets Transiting M Dwarf Stars

The Astronomical Journal
Earth-sized planets transiting M dwarf stars present one of the best opportunities with current facilities for studying the atmospheric and bulk compositions of terrestrial worlds. Here, we statistically validate five new transiting Earth and super-Earth

A METHOD FOR DETERMINING THE PHYSICAL PARAMETERS OF HOT SUPERGIANTS BASED ON SPECTRAL ENERGY DISTRIBUTION ANALYSIS

Physical Sciences and Technology
This study determines the physical parameters of B- and A-type hot supergiants through the construction and analysis of their spectral energy distributions (SEDs).

Subaru High-z Exploration of Low-luminosity Quasars (SHELLQs). XXI. Candidate Red Quasars at z ≥ 6 from Near-infrared Photometry

The Astrophysical Journal
We present an analysis of near-infrared photometry of 59 quasars at 5.83  −24 mag) of the sample. This luminosity trend may support the idea that red quasars represent an evolutionary stage preceding unobscured quasars, often invoked in the merger-driven

Estimating the luminosities of protostars with limited infrared photometry

Monthly 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 ...
