Measuring ultracool properties from the UKIDSS Large Area Survey
(EDP Sciences, 2013)
We discuss the properties and of ultracool and brown dwarfs that can be measured from current large area surveys and how fundamental parameters, such as the mass function and formation history can be measured, describing ...
Benchmark cool companions : Ages and abundances for the PZ Tel system
(2012-03)
We present new ages and abundance measurements for the pre-main sequence star PZ Tel. PZ Tel was recently found to host a young and low-mass companion. Using FEROS spectra we have measured atomic abundances (e.g. Fe and ...
