Old but still warm: Far-UV detection of PSR B0950+08
, 2017 We report on a Hubble Space Telescope detection of the nearby, old pulsar B0950+08 ($d\simeq 262$ pc, spin-down age 17.5 Myr) in two far-ultraviolet (FUV) bands.

A temperature-dependent nonlinear neutron transport problem
Journal of Mathematical Analysis and Applications, 1979 The effect of a temperature-dependent feedback on the behavior of a nuclear reactor was studied in several papers [IA] by using the time-dependent diffusion approximation. Feedback was assumed to act only through the multiplication factor. In the papers of Belleni-Morante and co-workers [5-81, the time evolution of a reactor was studied taking into ...

Rotating proto-neutron stars: spin evolution, maximum mass and I-Love-Q relations
, 2014 Shortly after its birth in a gravitational collapse, a proto-neutron star enters in a phase of quasi-stationary evolution characterized by large gradients of the thermodynamical variables and intense neutrino emission.

Pulse-phase resolved spectroscopy of continuum and reflection in SAX J1808.4-3658
, 2010 We perform phase-resolved spectroscopy of the accreting millisecond pulsar, SAX J1808.4-3658, during the slow-decay phase of the 2002 outburst. Simple phenomenological fits to RXTE PCA data reveal a pulsation in the iron line at the spin frequency of the

Neutron scattering at high temperature and levitation techniques
Journal of Physics: Conference Series, 2014 Studies of the liquid state present an obvious fundamental interest and are also important for technological applications since the molten state is an essential stage in various industrial processes (e.g. glass making, single crystal growing, iron and steel making).

Neutron Capture by 208Pb at Stellar Temperatures
The Astrophysical Journal, 1977 Neutron capture cross section data for isotopically enriched /sup 208/Pb were taken at the Oak Ridge electron linear accelerator time-of-flight facility and analyzed for nuclear resonance capture parameters up to 825 keV. Two new capture resonances at energies (43.29 and 47.26 keV) near stellar interior temperatures were found.
