Neutron st
ars are one of the densest strongly-interacting many-body systems in our u
niverse. A main challenge in describing the structure and dynamics of neut
ron stars steams from our limited understanding of the nuclear interaction
at high-densities (i.e. short-distances) and its relation to the underlay
ing quark-gluon substructure of nuclei.
\n
\nIn this talk I will
present new results from high-energy electron scattering experiments that
probe the short-ranged part of the nuclear interaction via the hard break
up of Short-Range Correlations (SRC) nucleon pairs. As the latter reach de
nsities comparable to those existing in the outer core of neutron stars\,
they represent &rsquo\;neutron stars droplets&rsquo\; who&rsquo\;s study c
an shed new light to the dynamical structure of neutron stars. Special emp
hasis will be given to the effect of SRCs to the behavior of protons in ne
utron-rich nuclear systems and how it can impact the cooling rates and equ
ation of state of neutron stars.  \;Pursuing a more fundamental unders
tanding of such interactions\, I will present new measurements of the inte
rnal quark-gluon sub-structure of nucleons and show how its modification i
n the nuclear medium relates to SRC pairs and short-ranged nuclear interac
tions. \;
\n
\nGiven time I will also discuss the developmen
t of new effective theories for describing short-ranged correlations\, the
way in which they relate to experimental observables\, and the emerging u
niversality of short-distance and high-momentum physics in nuclear systems
