TLDR
In this article, a global study of low mass, young stellar object (YSO) surface densities in nearby star forming regions based on a comprehensive collection of Spitzer Space Telescope surveys is presented.Abstract:
We present a global study of low mass, young stellar object (YSO) surface densities (�) in nearby (< 500 pc) star forming regions based on a comprehensive collection of Spitzer Space Telescope surveys. We show that the distribution of YSO surface densities in the solar neighbourhood is a smooth distribution, being adequately described by a lognormal function from a few to 10 3 YSOs per pc 2 , with a peak at � 22 stars pcread more

On the fraction of star formation occurring in bound stellar clusters
TL;DR: In this article, the authors present a theoretical framework in which bound stellar clusters arise naturally at the high-density end of the hierarchy of the interstellar medium (ISM) and due to short free-fall times, these high density regions achieve high local star formation efficiencies, enabling them to form bound clusters.

The big problems in star formation: The star formation rate, stellar clustering, and the initial mass function
TL;DR: A review of the current state of the field of star formation can be found in this article, focusing on three central questions: What controls the rate at which gas in a galaxy converts to stars? What determines how those stars are clustered, and what fraction of the stellar population ends up in gravitationally-bound structures?

Embedded Clusters in Molecular Clouds
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.
