PublicaciónThe kinematic behaviour of optical recombination lines and collisionally excited lines in Galactic planetary nebulae*†
The kinematics of the plasma in 14 planetary nebulae (PNe) is analysed by measuring the expansion velocities (Vexp) of different ions as derived from their...

PublicaciónThe kinematic structure of the unusual outflow source SH 2-71
We have undertaken high resolution spectroscopy and IR photometry of the extended planetary nebula Sh 2-71. As a consequence, we note evidence for a discoidal...

PublicaciónThe kinematics of local thick discs do not support an accretion origin⋆
Thick discs are nearly ubiquitous components of the discs of present-day galaxies. It has been proposed that a fraction of their stars have been accreted. Here...
