The Frequency of Wide Companions to Planet-Host Stars: A New Wide Brown Dwarf Companion
The aim of the project is to improve our knowledge of the multiplicity of planet-host stars at wide physical separations. We cross-matched approximately 6,200...
We analyzed far-UV (FUSE), UV (HST, IUE) and optical spectra of hot massive stars in the Milky Way with non-LTE, line-blanketed models with sphericity and...
The fundamental parameters of the central stars of eight WR ring nebulae
We describe work that has recently been completed on deriving the fundamental parameters of eight WR stars through the photoionization modelling of their...

The Fundamental Plane of E Galaxies in Compact Groups
We present a study focusing on the nature of compact groups through the study of their elliptical galaxies. We determine central velocity dispersions (σo) for...
We report recent results from the photometric follow-up study we are conducting in the context of the SAURON project. We use ground-based MDM V -band and...
The global properties of early-type galaxies are fairly well described through a linear relation (the Fundamental Plane, FP [2],[3]) in the space defined by...
