Jun 10, 2015 at 10:06 comment added ProfRob Ah that "Walter"! I'll check it out - I am interested in young moving groups and similar kinematic structures.
Jun 10, 2015 at 9:50 comment added Walter @RobJeffries Look at my article and any quoting it.
Jun 9, 2015 at 6:05 comment added ProfRob Can you provide something that backs up the item about velocity clumps in the solar neighbourhood are due to resonance with the bar - genuinely interested.
