Emerging trends in metallicity and lithium properties of debris disc stars
Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently studied. In this paperExpand
Correlations between the stellar, planetary, and debris components of exoplanet systems observed by Herschel
Context. Stars form surrounded by gas- and dust-rich protoplanetary discs. Generally, these discs dissipate over a few (3–10) Myr, leaving a faint tenuous debris disc composed of second-generationExpand
Connecting substellar and stellar formation: the role of the host star’s metallicity
Context. Most of our current understanding of the planet formation mechanism is based on the planet metallicity correlation derived mostly from solar-type stars harbouring gas-giant planets. Aims. ToExpand
Analysis of the Chemical Composition of the Atmospheres of Stars with Debris Disks and Planetary Systems
Spectroscopic studies of seven low mass stars in spectral classes F, G, and K are presented. Four of these (HD 1581, HD 10700, HD 17925, and HD 22484) have debris disks and for two of them (HD 22049Expand
Stellar clustering and orbital architecture of planetary systems
Revealing the mechanisms shaping the architecture of planetary systems is crucial for our understanding of their formation and evolution. In this context, it has been recently proposed that stellarExpand
Towards testing the tidal downsizing hypothesis for planet formation
TOWARDS TESTING THE TIDAL DOWNSIZING HYPOTHESIS FOR PLANET FORMATION
Planets, debris and their host metallicity correlations
Recent observations of debris discs, believed to be made up of remnant planetesimals, brought a number of surprises. Debris disc presence does not correlate with the host star's metallicity, and mayExpand
Investigating the planet–metallicity correlation for hot Jupiters
We investigate the giant planet-metallicity correlation for a homogeneous, unbiased set of 217 hot Jupiters taken from nearly 15 years of wide-field ground-based surveys. We compare the host starExpand

Various papers on the formation of stars and planets are presented. The general topics addressed include: molecular clouds and star formation, young stellar objects and circumstellar disks, chemistryExpand
Metallicity, debris discs and planets
We investigate the populations of main-sequence stars within 25 pc that have debris discs and/or giant planets detected by Doppler shift. The metallicity distribution of the debris sample is a veryExpand
DUSTY DEBRIS AROUND SOLAR-TYPE STARS: TEMPORAL DISK EVOLUTION
Using ISO-ISOPHOT, we carried out a survey of almost 150 stars to search for evidence of emission from dust orbiting young main-sequence stars, both in clusters and isolated systems. Over half of theExpand
Debris disks as signposts of terrestrial planet formation
There exists strong circumstantial evidence from their eccentric orbits that most of the known extra-solar planetary systems are the survivors of violent dynamical instabilities. Here we explore theExpand

A Spitzer Infrared Spectrograph Study of Debris Disks Around Planet-host Stars
Since giant planets scatter planetesimals within a few tidal radii of their orbits, the locations of existing planetesimal belts indicate regions where giant planet formation failed in bygoneExpand

On the Semimajor Axis Distribution of Extrasolar Gas Giant Planets: Why Hot Jupiters are Rare Around High-Mass Stars
Based on a suite of Monte Carlo simulations, I show that a stellar-mass-dependent lifetime of the gas disks from which planets form can explain the lack of hot Jupiters/close-in giant planets aroundExpand
Evolved stars suggest an external origin of the enhanced metallicity in planet-hosting stars
Aims. Exo-planets are preferentially found around high metallicity main sequence stars. We aim at investigating whether evolved stars share this property, and what this tells about planet formation.Expand
