Abstract:
Massive stars are of interest as progenitors of supernovae, i.e.
neutron stars and black holes, which can be sources of gravitational
waves. Recent population synthesis models can predict neutron star and
gravitational wave observations but deal with a fixed supernova rate
or an assumed initial mass function for the population of massive
stars. Here we investigate those massive stars, which are supernova
progenitors, i.e. with O- and early B-type stars, and also all
supergiants within 3kpc. We restrict our sample to those massive
stars detected both in 2MASS and observed by Hipparcos, i.e. only
those stars with parallax and precise photometry. To determine the
luminosities we calculated the extinctions from published multi-colour
photometry, spectral types, luminosity class, all corrected for
multiplicity and recently revised Hipparcos distances. We use
luminosities and temperatures to estimate the masses and ages of these
stars using different models from different authors.
