Magnetic, chemical and rotational properties of the Herbig Ae/Be binary system HD 72106
Recently, magnetic fields have been detected in a handful of pre-main sequence Herbig Ae and Be (HAeBe) stars. This hints at an evolutionary connection between magnetic HAeBe stars and Ap and Bp stars. Ap/Bp stars are ...
The surface brightness distribution of Virgo cluster galaxies
We have acquired near-IR H and optical $g$,$r$,$i$,$z$ imaging for a sample of 299 Virgo cluster galaxies down to a limiting magnitude of B$_T$=16.0 mag. The low sensitivity of near-IR wavelengths to dust extinction is ...
A numerical study of galaxy mass density profiles
An understanding of the shape and nature of galaxy density profiles remains a major challenge to galaxy structure studies. The physical mechanisms thought to control these profiles include star formation rates and dynamical ...
