Full textLn the last decade, the field of the search and study of cold companions around solar neighborhood stars has greatly improved. The study of low mass stellar compani?ns and brown dwarf companions brings important constraints in the unclerstanding of stellar formation. The study of planetary sys¬tems allows us to understand the formation of our own solar system. Up to now, most systems were cliscovered with the radial velocities technique. This technique is an indirect method that prevents from analysing the photons of a cold companion. The next step consists in detecting and analysing the photons of such companions. Many projects of high contrast imaging instruments have been re¬cently cleveloped in orcier to fulfil this task. This thesis was inspired by the scientific preparation and the development of such a project : the SPHERE instrument that will be installed at the Very Large Telescope in Chile in 2012. Ln the first part, 1 introduce the astrophysical questions that motivate the search for star companions and de scribe the two observation techniques that 1 used during my PhD : high contrast imaging and radial velocities techniques. A state of art about the status of the search for low mass stellar compa¬nions, brown clwarf companions and planetary companions is also done. Ln the second part, 1 clescribe the observation, data reduction and analysis techniques 1 used. The third part presents a study on the brown dwarf desert around around solar type stars that were selected from a sample of stars with radial velocity drift. Ln the fourth part, 1 clevelop an observation work that consists in detecting the planetary or brown dwarf companions around red dwarfs. The last part is devoted to the description of the SPHERE instrument and to my own contribution into this instrumental project

Full textMy work takes place in the dynamic context of the direct detection of low mass companions (brown dwarfs, extrasolar planets). I intent to characterize their physical and chemical properties, and to understand the mechanisms that lead to their formation and drive their evolution. This requires using high contrast and high angular resolution techniques in order to resolve the close environment of the stars without being limited by their flux. I had the opportunity to participate to observational campaigns so as to detect new sources. I developed a set of data analysis tools designed to extract the spectra and the flux of the objects into photometric bands. Finally, I used this information to study the physical (radius, mass, age) and the atmospheric (composition, effective temperature, surface gravity) properties of these objects. The first part of this manuscript focus on the detection of young (age < 100 Myrs) low mass companions using imaging. I describe a set of reduction and analysis tools dedicated to the angular differential imaging technique. These tools have been used on data coming from the NaCo instrument located on the Very Large Telescope (Chile). They allowed re-detecting the extrasolar planet β Pictoris b. This companion is closer to its star than any of the extrasolar planets detected directly so far. This discovery brings the definite proof that giant planets can form in less than 12 million years within disks. I finally present a complementary analysis I conducted to initiate the characterization of this valuable object. The determination of the spectroscopic properties of young and low mass objects in the near infrared (1. 1-2. 5 µm) constitutes the second aspect of my work (and is reported in the last part of the manuscript). I started developing analysis and processing tools dedicated to data gathered on the adaptive optics assisted integral field spectrograph SINFONI. These efforts were used to analyze the spectrum of the planet/brown dwarf companion AB Pic b. This work was pursued to built a spectral library of young objects. This library brings a collection of reference spectra, necessary for the study of other young companions. It also brings new constraints on the latest generation of atmospheric models of cool objects. To conclude, I used the instrument NaCo and SINFONI to characterize the binary system TWA 22AB that could calibrate evolutionary models of low mass objects

Full textDespite the low deuterium abundance in the Universe (D/H ~ 1. 5x10-5), high abundances of deuterated molecules are detected in star forming regions, with a fractionation higher than the cosmic abundance of deuterium by several orders of magnitude. We study in this thesis the physical and chemical processes leading to the high molecular deuteration observed in low-mass protostellar environments. We present observations of deuterated molecules (namely methanol, formaldehyde and water) both in the gas and in the icy mantles of dust grains in the envelope surrounding such objects. Millimeter observations unveiled a high deuteration of methanol in the gas of the envelope. In particular, triply-deuterated methanol was detected with a fractionation CD3OH/CH3OH ~ 1% in IRAS16293-2422. The observed fractionations are consistent with the scenario of formation of methanol on dust grain surfaces. Deuterated methanol and formaldehyde were then searched for and detected on a sample of low-mass Class 0 protostars, suggesting that this high deuteration is common in this class of objects. Analysis of the gas-phase water emission in the IRAS16293-2422 envelope leads paradoxically to a fractionation one order of magnitude lower, in agreement with the upper limit on water deuteration in ices, derived by near-infrared observations towards slightly more evolved objects. The last chapter of the thesis presents a grain chemistry model that studies in details water fractionation
