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 pc

- The dynamical state of stellar structure in star‐forming regions (2011, background): “…& Goodwin 2006; Goodwin & Bastian 2006) has recently been challenged by observational studies suggesting that stars form with a continuous distribution of densities, of which only the high-density tail eventually leads to bound stellar clusters (Bressert et al.2010; Gieles & Portegies Zwart 2011).”
- Kinematics in Young Star Clusters and Associations with Gaia DR2 (2018, background): “Studies of cluster density have shown that there is no density threshold that divides “clustered” and “distributed” star formation (e.g., Bressert et al. 2010; Gieles et al. 2012; Kuhn et al. 2015b), and uncertainties in measurements of system masses and kinematics limit dynamical modeling.”
- The big problems in star formation: The star formation rate, stellar clustering, and the initial mass function (2014, background): “In nearby clouds, we see that stars form in a highly inhomogeneous fashion, with the stellar surface density varying by orders of magnitude even within the limited range of star-forming environments found within ∼ 1 kpc of the Sun (Gutermuth et al. 2009; Bressert et al. 2010; Gutermuth et al. 2011).”
