Neutron Star masses and radii

Neutron Star masses and radii. NS Masses. Stellar masses are directly measured only in binary systems Accurate NS mass determination for PSRs in relativistic systems by measuring PK corrections Gravitational redshift may provide M/R in NSs by detecting a known spectral line,

The last days of massive stars

The last days of massive stars. Outer layers expand as helium core contracts Helium fuses to form carbon, carbon fuses with helium to make oxygen, and heavier and heavier nuclei get built until iron (Fe) is made

THE FINAL FRONTIER.

SPACE. THE FINAL FRONTIER. STARS. A RARE IMAGE. This is a very rare image, as they do not last for long. For many stars these radiant explosions only happen for a brief period in the life. (example on the left). HD 148937.
