Hibernation Revived by Weak Magnetic Braking [PDF]
, 2006 Cataclysmic variables undergo periodic nova explosions during which a finite mass of material is expelled on a short timescale. The system widens and, as a result, the mass-transfer rate drops.

The Origin of the Mass-Metallicity relation: an analytical approach [PDF]
, 2010 The existence of a mass-metallicity (MZ) relation in star forming galaxies at all redshift has been recently established. We aim at studying some possible physical mechanisms contributing to the MZ relation by adopting analytical solutions of chemical ...

Propulsion and launching analysis of variable-mass rockets by analytical methods
Propulsion and Power Research, 2013 In this study, applications of some analytical methods on nonlinear equation of the launching of a rocket with variable mass are investigated. Differential transformation method (DTM), homotopy perturbation method (HPM) and least square method (LSM) were

Falling chains as variable mass systems: theoretical model and experimental analysis
, 2012 In the present paper we revisit, theoretical and experimentally, the fall of a folded U-chain and of a pile-chain. The model calculation implies the division of the whole system into two subsystems of variable mass, allowing to explore the role of ...

The role of heavy quarks in light hadron fragmentation [PDF]
, 2016 We investigate the role of heavy quarks in the production of light flavored hadrons and in the determination of the corresponding non perturbative hadronization probabilities.

Low Speed Orientation Control Using Variable Mass System: Application In Solar Panel
Journal of Sustainable Development of Energy, Water and Environment Systems, 2023 This study offers a mechanism to control low-speed orientation using semi-active control. The semi-active system consists of a variable mass system and a torsional spring. The torque generated by a variable mass system controls the platform’s
