TL;DR: The first extensive catalog of galactic embedded clusters is compiled, finding that the embedded cluster birthrate exceeds that of visible open clusters by an order of magnitude or more indicating a high infant mortality rate for protocluster systems.

TL;DR: In this paper, the authors report the results of the first sensitive L-band survey of the intermediate-age (2.5-30 Myr) clusters NGC 2264, NGC 2362, and NGC 1960.

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: Sensitive near-infrared measurements of the light from background stars as it is absorbed and scattered by trace amounts of dust are used to probe the internal structure of the dark cloud Barnard 68 with unprecedented detail and find the cloud's density structure to be very well described by the equations for a pressure-confined, self-gravitating isothermal sphere that is critically stable according to the Bonnor–Ebert criteria.

TL;DR: In this article, a method for mapping the distribution of dust through a molecular cloud using data obtained in large-scale, multi-wavelength, infrared imaging surveys is described, which combines direct measurements of near-infrared color excess and certain techniques of star counting to derive mean extinctions and map the dust column density distribution through a cloud at higher angular resolutions and greater optical depths.
