TL;DR: In this paper, high-sensitivity IRAS co-added survey data, coupled with new high sensitivity near-IR observations, are used to investigate the nature of embedded objects over an 4.3sq-pc area comprising the central star-forming cloud of the Ophiuchi molecular complex.

TL;DR: In this article, the two spiral arms appear to start at the ends of a bar in the nuclear region and extend beyond the star-forming ring, and the star forming ring is very circular except for a region near M32 where it splits.

TL;DR: In this article, a survey of NGC 2244 from 3.6 to 24 μm with the Spitzer Space Telescope is presented, which gives a detailed look at disk survivability within the hot-star-dominated environment in this cavity.

TL;DR: In this article, a survey of NGC 2244 from 3.6 to 24 micron with the Spitzer Space Telescope is presented, showing that the central cavity surrounding the multiple O and B stars contains a large amount of cool dust visible only at 24micron.

TL;DR: In this article, a survey of the 30 Myr old cluster NGC 2547 for planetary debris disks using Spitzer was conducted, showing that the inner 0.1-1 AU parts of disks around solar-type stars clear out very thoroughly by 30 Myr of age.
