Probing Massive Star Nucleosynthesis with Data on Metal-Poor Stars and the Solar System [PDF]
EPJ Web of Conferences, 2022 Metal-poor stars were formed during the early epochs when only massive stars had time to evolve and contribute to the chemical enrichment. Low-mass metal-poor stars survive until the present and provide fossil records of the nucleosynthesis of early ...

THE PHYSICAL MEANING OF THE TITIUS-BODE FORMULA
Odessa Astronomical Publications, 2016 It is proposed an special hypothesis of the formation of symmetric objects in space with the help of the interference of standing waves which act in the process of evolution of the primordial gas-dust cloud including the formation of the Solar system ...

The dynamics of Wolf numbers based on nonlinear dynamo with magnetic helicity: comparisons with observations [PDF]
, 2016 We investigate the dynamics of solar activity using a nonlinear one-dimensional dynamo model and a phenomenological equation for the evolution of Wolf numbers. This system of equations is solved numerically. We take into account the algebraic and dynamic

The formation of the solar system
, 2015 The solar system started to form about 4.56 Gyr ago and despite the long intervening time span, there still exist several clues about its formation. The three major sources for this information are meteorites, the present solar system structure and the ...
