TL;DR: The Spitzer Space Telescope, NASA's great Observatory for infrared astronomy, was launched 2003 August 25 and is returning excellent scientific data from its Earth-trailing solar orbit as mentioned in this paper.

TL;DR: In this paper, the extinction ratio between two of the filters, e.g., AJ/AK, is required to calculate A[λ]/AK from those measured ratios, which shows a flattening across the 3-8 μm wavelength range, roughly consistent with the extinction measurements derived by Lutz and coworkers for the sight line toward the Galactic center.

TL;DR: The NASA Exoplanet Archive as mentioned in this paper is a database and toolset for the exoplanet community, containing properties of all published exoplanets, Kepler planet candidates, threshold-crossing events, data validation reports and target stellar parameters, light curves from the Kepler and CoRoT missions and from several ground-based surveys, and spectra and radial velocity measurements from the literature.

TL;DR: In this paper, a new census of the stellar and substellar members of the young cluster IC 348 is presented, which contains a total of 288 members, 23 of which are later than M6 and thus are likely to be brown dwarfs.

TL;DR: In this article, the spectral energy distribution slopes in the IRAC spectral range were used to classify the Orionis cluster into three classes: non-excess stars, stars with optically thick disks (such as classical T Tauri stars), and stars with evolved disks.
