In this paper, we present a study of the abundances of Si, Ca, Sc, Ti, V, Cr, Mn, Co, and Ni in a large set of stars known to harbor giant planets, as well as...

PublicationFine structure in the local interstellar medium.
The authors examine, using K I and Na I absorptions, a generally conical volume out to some 200 pc from the Sun placing constraints on a number of the...

PublicationFluorine in the Solar Neighborhood: No Evidence for the Neutrino Process
Asymptotic giant branch (AGB) stars are known to produce “cosmic” fluorine, but it is uncertain whether these stars are the main producers of fluorine in the...

PublicationGaia Early Data Release 3. The Gaia Catalogue of Nearby Stars
Aims: We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue...

PublicationHabitable Planets Eclipsing Brown Dwarfs: Strategies for Detection and Characterization
Given the very close proximity of their habitable zones, brown dwarfs (BDs) represent high-value targets in the search for nearby transiting habitable planets...

PublicationHalo Streams in the Seventh Sloan Digital Sky Survey Data Release
We have detected stellar halo streams in the solar neighborhood using data from the seventh public data release of the Sloan Digital Sky Survey (SDSS), which...

PublicationHigh-resolution observations of interstellar NA I and K I absorptions towards giants within 200 PC from the sun
The first results of a program of observations designed to probe the structure and kinematics of the Local Interstellar Medium (LISM) using the Queen's...

PublicationInflow of Gas to the Solar Neighborhood during Evolution of the Galactic Disk
We discuss several lines of evidence indicating that gas is flowing into the solar neighborhood and go on to offer a theoretical framework to explain this...

PublicationMG II observed in the local interstellar medium - The local cloud
Observations of interstellar absorptions superposed on the chromospheric Mg II emissions of nearby cool stars have been used to explore the structure of the...
