The mass and helium discrepancy in massive stars: the case VELA X-1
A NLTE-analysis is presented of high S/N spectra of the optical component of the standard massive X-ray binary Vela X-1. In combination with the orbital...
The mass and helium discrepancy in massive stars: the case Vela X-1.
A NLTE-analysis is presented of high S/N spectra of the optical component of the standard massive X-ray binary Vela X-1. In combination with the orbital...
The mass content of the Sculptor dwarf spheroidal galaxy
We present a new determination of the mass content of the Sculptor dwarf spheroidal galaxy, based on a novel approach which takes into account the two distinct...
The Mass Distribution of White Dwarfs: An Unwavering Obsession
We discuss some of our current knowledge of the mass distribution of DA and non-DA stars using various methods for measuring white dwarf masses including...
The Mass Function at the End of the Main Sequence: The M35 Open Cluster
We present very deep RIc photometry of the M35 open cluster. We have covered 30' \times 30', equivalent to about a fourth of the total area of the cluster. The...
The mass function beyond the substellar limit in the Pleiades cluster
We present results of our search for free floating brown dwarfs in the Pleiades star cluster showing that the process of star formation does not stop at the...
