Analytical solutions for radiation-driven winds in massive stars - II. The δ-slow regime
(OXFORD UNIV PRESS, 2021-04-29)
Accurate mass-loss rates and terminal velocities from massive stars winds are essential to obtain synthetic spectra from radiative transfer calculations and to determine the evolutionary path of massive stars. From a ...
Mechanical and structural assessment of CuZr metallic glasses rejuvenated by thermal-pressure treatments
(ELSEVIER, 2021-09-06)
Thermal-pressure treatments have proved to bring metallic glasses (MGs) to rejuvenated states. However the knowledge regarding their effect on the mechanical properties and atomic structure is still limited. Here, molecular ...
