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 ...
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 ...
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 ...
