I am interested in the formation and evolution of the Solar System. As a geologist/spectroscopist, I am interested in surfaces of planets, comets and asteroids, but I also study the volatiles of comets with my expertise in VIS/NIR spectroscopy. I have divided my research in two directions: 1- Differentiated bodies like the Moon and Mercury to understand the thermal evolution of these bodies through their volcanic history, 2- Small bodies like comets and asteroids because they are more pristine than big planets and can constrain the origin of the Solar System.

II study magnetic fields on the sun and aim to contribute in answering the following questions: What causes the formation of sunspots, the triggering of solar flares and coronal mass ejections? What is the distribution of the small-scale magnetic field on the solar surface and what defines its origin, emergence, evolution and disappearance? What are the relevant physical mechanisms governing the dynamics of the magnetized gas?

For my work I use polarimetric data and filtergrams from ground based instruments such as SOLIS (Synoptic Optical Long-term Investigations of the Sun) as well as from satellites dedicated to solar physics such as the HINODE observatory. I specialize in the technique of Stokes Inversion to infer the magnetic field vector and also use results of realistic MHD codes to compare to observations and find out more about the underlying fundamental physics of the observed phenomena.

My main scientific interests include the search and study of transiting extrasolar planets within the context of the CoRoT space mission. I am involved in the spectroscopic follow-ups of the planet-hosting star candidates detected by CoRoT, in order to confirm the planetary nature of the transiting objects, derive the orbital parameters, and finally determine the physical properties of the star-planet system.

Combining the CoRoT photometric database with spectroscopy, I study: the stellar population in the CoRoT fields; differential rotation in active low-mass stars; eclipsing binaries with pulsating components or very low-mass stars.

I also study the star formation process in small cometary clouds and in the immediate surroundings of isolated Herbig Ae/Be stars.

My research focuses on planetary atmospheres, including topics as diverse as photochemistry, airglow, atmospheric escape, radiative transport, spectroscopy and polarization. I consider myself a theorist/modeler, but I am keen to apply my knowledge and tools in the design/interpretation of observations. Planets of the Solar System I have worked with include Earth, Mars, Venus, and Jupiter. Since 1995, it has become evident that the possibilities of planet types are vast and, so, I am very interested in the emerging field of exoplanetary atmospheres. My graduate work on the evaporation of HD 209458b is still used in the investigation of hot Jupiters and other exoplanets under strong irradiation conditions.

Keywords

• Nightglow in the Venus atmosphere
• Lightning in the Solar System

My research focuses on studying the properties of compact stellar systems, i.e. globular clusters, galaxies' nuclei , ultra compact dwarf galaxies, using space and ground based imaging and spectroscopy (from optical to NIR wavelengths). Such stellar systems form at the peak epoch(s) of star formation in a galaxy. Therefore, a firm knowledge of, e.g. their age, metallicity, structural parameters, spatial distributions, provides a robust tool to reconstruct host galaxy formation history (mergers, tidal interactions).

My scientific interest is star formation and I have currently two main research activities: i) within the context of the Planck mission, prepare for the use of HFI and LFI data to derive a census of ultra-compact HII regions and massive young stellar objects in the mm and submm; ii) Using XMM and Chandra data, study the X-ray emission of YSOs, investigating the influence of X-ray emission on the circumstellar environment. So far, I have analysed X-ray data for L1551 in Tau, Serpens, S106 and Rho-Oph.

My research is focused on small bodies in the solar system, like Kuiper Belt objects, Centaurs, comets, Trojans, or asteroids. They are believed to be the remnants of planet formation. Strategically, understanding the origin and evolution of these objects is a key step towards explaining the processes at work during the formation and evolution of the solar system. At this point, we still don't know which observed physical and orbital characteristics of the small bodies, after 4.5 Gyr of physico-dynamical evolution in a time-varying radiative and collisional environment, will ultimately provide the best clues to their origin. The problem is tractable though, and can be addressed in suitable steps.

Dynamical studies have highlighted possible links between small body populations, yet there is no compelling evidence that the solar system evolved according to any of the current scenarii because there are still many things we don't understand about the physical connections between these small body populations. Part of my work aims at constraining some of their physical properties, in particular the surface composition, through visible and near-infrared spectroscopy performed on the world's largest telescopes. I am particularly interested in the volatile and organic content of KBOs, Centaurs, Trojans, comets and asteroids, and the similarities/differences between these populations. The other aspect of my work is related to the thermal history of icy objects. I try to understand with numerical simulations how ice can survive on some objects, how the composition and other physical properties can evolve with time, why/how some objects display comet-like activity, etc.

Keywords

• solar system formation
• small bodies, comets, asteroids, KBOs
• surface composition, volatiles, ices
• cometary activity, cryovolcanism
• thermal evolution modelling
• physical link between populations, evolution

My main research topic is star and planet formation, specifically the structure and evolution of circumstellar disks around young stars. I focus much of my work on young eruptive stars (FUors and EXors). These are pre-main sequence objects with temporarily increased accretion rate resulting in powerful brightenings in the whole optical-infrared regime. My goal is to understand the physics behind the accretion process and the effect of the increased heating on the disk. I am also interested in variability of young stellar objects in general at various wavelengths from the optical to the millimeter, and what it can tell us about disk structure. Part of my work focuses on debris disks, and the relationship of debris dust and planet formation. I am experienced in several observational techniques from imaging and spectroscopy through polarimetry to interferometry.

• primordial and debris disks
• accretion process during star formation
• eruptive phenomenon during pre-main sequence

The majority of my research concerns the development of theoretical and statistical techniques broadly related to gravity. In particular, I study the various ways stars interact with each other in dense stellar environments. I often apply these methods to observations of dense star clusters, where the stellar densities can become so high that direct collisions can even occur between stars.

My main scientific work is concerning star formation. At the moment the focus is on aspects which can be addressed with the Herschel data: disks around young stars, circumstellar matter and far-infrared variability. I am gradually moving toward topics which will benefit from the Gaia data of young stellar clusters: membership, dynamics and initial luminosity or mass function. The binding element between Herschel and Gaia studies is concentration on close by targets in the Gould Belt system.

My research focuses on the the structure and dynamics of the terrestrial magnetotail, particularly the properties of and asymmetries in the particle distributions in the magnetotail plasma sheet. Examining these distributions allows us to understand how mass and energy enter the magnetosphere from the solar wind and ionosphere, which particle acceleration processes are the most effective in the magnetotail and ultimately how the seed population for the ring current and radiation belts is formed. I am also working on how the particle acceleration that happens in the magnetotail and closer to the Earth results in the bright visible aurora. I use data from ESA's Cluster and Double Star missions in my research.
