Structure of Early-Type Galaxies
Astrophysics and Space Science, 2001We outline the results of a two-dimensional (2D) fit to the light distribution of early-type galaxies belonging to a complete volume-limited sample and discuss briefly the significant correlations among the structural parameters. In particular we reconfirm that the lack of structural homology is probably a characteristic of hot stellar systems.

Supernovae in early-type galaxies
Astrophysics and Space Science, 1989It is argued that all SNI come from short-lived stars and do not occur in a typical, isolationist, gas-free early-type galaxy. SNI occur only in those galaxies which accrete gas and form stars. SN properties of E/SOs are, therefore, determined by environmental factors.

Soft merging in early-type galaxies.
1997Statistical, photometric, and kinematical arguments suggest that encounters, accretion, and merging of galaxies are likely the key mechanisms for the formation of present-day ellipticals. While major merger events leave strong and clearly measurable signatures, those left by minor (or "soft") ones are usually rather tricky to observe.

Early-type dwarf (dE) galaxies exhibit a puzzling variety of observable properties. Are they at all a single class of objects? Could some of them be “primordial” galaxies, while others were created by environmental processes? Here I provide a brief overview of early-type dwarfs, focusing on galaxy clusters, where dEs are the dominant galaxy population ...

The Kinematics of Early Type Galaxies
1989Recent observations of the kinematics of the central regions of M 31, M 32 and NGC 4594 at high spatial resolution have revealed steep central velocity gradients and high velocity dispersions that have been interpreted as indicating the presence of large central masses. Axisymmetric, constant mass-to-light ratio models can account for the steep rise in

Isolated early-type galaxies are very rare, yet offer important leverage in terms of testing galaxy formation models free of environmental processes. They also act as a valuable control sample. Here I briefly summarise past samples of isolated early-type galaxies and a new well-defined sample.
