Constraints on physics of neutron stars from X-ray observations [PDF]

, 2013
I summarize some constraints on the physics of neutron stars arising from X-ray observations of the surfaces of neutron stars, focusing on using models of low-magnetic-field neutron star atmospheres to interpret their X-ray spectra.

Neutron skins and neutron stars

Physical Review C, 2012
Background: The neutron skin of a heavy nucleus as well as many neutron-star properties are highly sensitive to the poorly constrained density dependence of the symmetry energy. Purpose: To provide for the first time meaningful theoretical errors and to assess the degree of correlation between the neutron-skin thickness of ${}^{208}$Pb and several ...

Effects of neutron exposure on the embryonic development of European sea bass (Dicentrarchus labrax), a candidate fish species for space aquaculture: simulated conditions on the ISS and during a lunar mission

Frontiers in Space Technologies
One of the scenarios for manned space exploration involves the presence of a community on a lunar base that is partially autonomous in terms of food production.

Observation of Ground-State Two-Neutron Decay [PDF]

, 2012
Neutron decay spectroscopy has become a successful tool to explore nuclear properties of nuclei with the largest neutron-to-proton ratios. Resonances in nuclei located beyond the neutron dripline are accessible by kinematic reconstruction of the decay ...
