Accreting White Dwarfs as Supersoft X-ray Sources

open access: yes, 2009
I review various phenomena associated with mass-accreting white dwarfs (WDs) in the view of supersoft X-ray sources. When the mass-accretion rate is low (\dot M_{acc} < a few \times 10^{-7} M_\sun yr^{-1}), hydrogen nuclear burning is unstable and nova ...

s-Process Nucleosynthesis in Advanced Burning Phases of Massive Stars

open access: yes, 2006
We present a detailed study of s-process nucleosynthesis in massive stars of solar-like initial composition and masses 15, 20,25, and 30 Msun. We update our previous results of s-process nucleosynthesis during the core He-burning of these stars and then ...

The primordial and evolutionary abundance variations in globular-cluster stars: a problem with two unknowns

open access: yes, 2015
We demonstrate that among the potential sources of the primordial abundance variations of the proton-capture elements in globular-cluster stars proposed so far, such as the hot-bottom burning in massive AGB stars and H burning in the convective cores of ...

A synergistic approach for thermal characteristic analysis of hibiscus rosa-sinensis/carbon nano-tubes/epoxy based hybrid composites using soft computing techniques

open access: yesMaterials Research Express
This study examines the thermal properties and combustion behavior of HRS/CNT hybrid polymer composites, focusing on how variations in CNT weight percentage, CNT diameter, sonication time, and composite thickness affect thermal conductivity, degradation ...

Study of the Pure Deuterium Fuel Burning Rate in Z-Pinch Devices with Magneto-Inertial Confinement

open access: yesEnergies
The burning rate of pure deuterium (D-D) fuel in Z-pinch devices with magneto-inertial confinement was studied in this paper. The system of particle and energy balance equations for D-D fuel burning with a mixed D-T-3He fusion cycle (D-D, D-T, and D-3He ...
