Thousands of transiting exoplanets have been discovered to date, thanks in great part to the Kepler space mission. As in all populations, and certainly in the case of exoplanets, one finds unique objects with distinct characteristics. Here we will describe the properties and behaviour of a small group of 'disintegrating' exoplanets discovered over

The low-surface brightness (LSB) Universe is one of the latest frontier in observational astronomy. However, uncovering the precious information contained in ultra-deep imaging is technically challenging. In this contribution, we will present one of the fundamental tools of LSB astronomers: the extended Point Spread Function (PSF). Having an

We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and metallicity. The models fit the density distributions, kinematic, and age and metallicity maps from integral field unit (IFU) spectroscopy observations. We validate the method and demonstrate

We report the discovery of a giant planet candidate transiting a white dwarf star. The planet candidate orbits its host star every 1.4 days, is about the size of Jupiter, and has a mass less than about 14 M Jup. The planet candidate orbits close enough to the white dwarf that it must have formed farther out to avoid destruction when the host star
