Direct imaging of exoplanets.
Most of the exoplanets known today have been discovered by indirect techniques, based on the study of the host star radial velocity or photometric temporal variations. These detections allowed the study of the planet populations in the first 5-8 AU from the central stars and have provided precious information on the way planets form and evolve at such separations. Direct imaging on 8-10 m class...
متن کاملFinding Terrestrial Exoplanets With Synthetic Radial Velocity Datasets
Within the past couple of years, our technology has become so precise that we have been able to unveil terrestrial planets inhabiting outside solar systems. Though we are currently unable to detect planets with Earth-like orbital properties, we can nonetheless contemplate what we might discover in the next few years. Utilizing the known distribution of extrasolar planets today and a variable me...
متن کاملFinding exoplanets orbiting young active stars – I. Technique
Stellar activity, such as starspots, can induce radial velocity (RV) variations that can mask or even mimic the RV signature of orbiting exoplanets. For this reason RV exoplanet surveys have been unsuccessful when searching for planets around young, active stars and are therefore failing to explore an important regime which can help to reveal how planets form and migrate. This paper describes a...
متن کاملAbundances in stars with exoplanets
Extensive spectroscopic studies of stars with and without planets have concluded that stars hosting planets are significantly more metal-rich than those without planets. More subtle trends of different chemical elements begin to appear as the number of detected extrasolar planetary systems continues to grow. I review our current knowledge concerning the observed abundance trends of various chem...
متن کاملLithium in stars with exoplanets⋆
We present a comparison of the lithium abundances of stars with and without planetary-mass companions. New lithium abundances are reported in 79 planet hosts and 38 stars from a comparison sample. When the Li abundances of planet host stars are compared with the 157 stars in the sample of field stars of Chen et al. (2001) we find that the Li abundance distribution is significantly different, an...
