$$\dot{M}_{BH} = \frac{4 \pi \rho G^2 M^2}{c_s^3} $$
For a low-mass star in a low-density medium and a high-mass star in a high-density medium,
the values are
$$\dot{M}_{BH} = 1.6\times10^{-7} \left(\frac{M}{M_\odot}\right)^2 \left(\frac{n}{10^4
\text{cm}^{-3}}\right) \mathrm{cm}^{-3}}\right) \left(\frac{c_s}{1
\text{km \mathrm{km s}^{-1}}\right)^{-3} \msun \peryr$$
$$\dot{M}_{BH} = 1.6\times10^{-4} \left(\frac{M}{10 M_\odot}\right)^2 \left(\frac{n}{10^5
\text{cm}^{-3}}\right) \mathrm{cm}^{-3}}\right) \left(\frac{c_s}{1
\text{km \mathrm{km s}^{-1}}\right)^{-3} \msun \peryr$$
The timescale for a 10\msun star to double its mass in a $n\sim10^5\percc$
medium is $\sim50$ kyr, but drops to only $5$ kyr for density
$n\sim10^6\percc$.

determined entirely by turbulence. In this description, the highest
overdensities in the turbulent medium become gravitationally unstable and
separate from the turbulent flow as they collapse into proto-stellar cores.
This idea has been a hot topic in the past few years, but
I will not address it
may be an overly
simplistic view.
Turbulence is appealing to theorists as it is a difficult problem to address
directly
with observations, but it may have great predictive power. If turbulence
is the dominant governing process of the ISM, then it is possible to derive a
reasonably robust star-formation theory based on the excursion set theory
successfully applied to cosmological structure formation
\citep{Hopkins2012b,Hennebelle2011a,Hopkins2012d}.
However, in reality, turbulence is just one of many processes governing the ISM
and star formation. Stellar feedback, in the form of radiation, winds,
supernovae, and outflows imposes a preferred driving scale on any individual
region, and in
many cases these processes will happen faster than turbulent
processes. The notion of \emph{initial conditions} for star formation,
while theoretically appealing, may prove too strong an oversimplification
when searching for a complete theory of star formation.
Throughout this
thesis. thesis, I consider and measure the drivers, effects and
properties of turbulence on a few different scales.
In the W5 and IRAS 05358 regions (Chapter \ref{ch:w5} and
\citet{Ginsburg2009}), I examined outflows as potential drivers of turbulence.
