We are obtaining spectra, spectral types and basic physical parameters for the nearly 3600 dwarf and giant stars earlier than M0 in the Hipparcos catalog within 40pc of the Sun. Here we report on results for 1676 stars in the southern hemisphere observed at Cerro Tololo Interamerican Observatory and Steward Observatory. These results include new, precise, homogeneous spectral types, basic physical parameters (including the effective temperature, surface gravity, and metallicity, [M/H]) and… Expand
Magnetic fields on young, solar-type stars
This thesis describes an investigation aimed at using spectropolarimetric observations of the magnetic fields of young solar-type stars to improve the understanding of the early development of solarExpand
Chromospheric activity of nearby Sun-like stars
Context.The chromospheric emission in the cores of the Ca IIH & K lines of late-type dwarfs is a well known indicator of magnetic activity that decreases with increasing stellar age.Aims.I use thisExpand
The HARPS search for southern extra-solar planets – XLV. Two Neptune mass planets orbiting HD 13808: a study of stellar activity modelling’s impact on planet detection
We present a comprehensive analysis of 10 years of HARPS radial velocities of the K2V dwarf star HD 13808, which has previously been reported to host two unconfirmed planet candidates. We use theExpand
Companions and Environments of Low-Mass Stars: From Star-Forming Regions to the Field
The lowest-mass stars, known as M-dwarfs, form target samples for upcoming exoplanet searches, and together with lower-mass substellar objects known as brown dwarfs, are among prime targets forExpand
The JCMT Gould Belt Survey: radiative heating by OB stars
Radiative feedback can influence subsequent star formation. We quantify the heating from OB stars in the local starforming regions in the JCMT Gould Belt survey. Dust temperatures are calculated fromExpand
Enhanced lithium depletion in Sun-like stars with orbiting planets
Li abundances are reported for an unbiased sample of solar-analogue stars with and without detected planets to find that the planet-bearing stars have less than one per cent of the primordial Li abundance, while about 50% of the solar analogueswithout detected planets have on average ten times more Li.

A Collage of Small Planets from the Lick–Carnegie Exoplanet Survey: Exploring the Super-Earth and Sub-Neptune Mass Regime*
Analysis of new precision radial velocity (RV) measurements from the Lick Automated Planet Finder (APF) and Keck HIRES have yielded the discovery of three new exoplanet candidates orbiting two nearbyExpand
Evolution of gas and dust in circumstellar environments: from protoplanetary discs to the formation of planets
Understanding the evolution of gas and dust in circumstellar discs is a major topic in present day astronomy, linked to one of the most interesting challenges: understanding the formation of planets.Expand
Stellar Chromospheric Activity
The Sun, stars similar to it, and many rather dissimilar to it, have chromospheres, regions classically viewed as lying above the brilliant photosphere and characterized by a positive temperatureExpand
Is multiplicity universal? : a study of multiplicity in the young moving groups
The young moving groups are collections of nearby (<200 pc), young (5-150 Myr) premain sequence stars; these stars offer us one of the best opportunities to characterise stellar multiplicity,Expand
