We present the discovery of sub-stellar mass companions to three stars by the ongoing Penn State - Toruń Planet Search (PTPS) conducted with the 9.2 m Hobby-Eberly Telescope.

Dwarf elliptical galaxies are the most common galaxy type in nearby galaxy clusters, yet they remain relatively poorly studied objects and many of their basic properties have yet to be quantified. In this contribution we present the preliminary results of a study of 4 Virgo and 1 field galaxy obtained with the SAURON integral field unit on the

This R&D project implements a new way of perception of the three-dimensional surrounding space, based exclusively in sounds and thus especially useful for the blind. The innate capability of locating sounds, the externalization of sounds played with headphones and the machine capture of the 3D environment are the technological pillars used for this

To investigate the origins of S0 galaxies, we present a new method of analysing their stellar kinematics from discrete tracers such as planetary nebulae. This method involves binning the data in the radial direction so as to extract the most general possible non-parametric kinematic profiles, and using a maximum-likelihood fit within each bin in

It has been known for sometime that the Milky Way is a barred disk galaxy. More recently several studies inferred from star count observations that the Galaxy must contain a separate, new, flat long bar component, twisted relative to the barred bulge. Here we use a simulation with a boxy bulge and bar to suggest that these observations can be
