A video about the discovery and study of WISE 0855 (rendered using the American Museum of Natural History's Digital Universe) is available at:https://www.youtube.com/watch?v=qT3pvWleFoU.As the Juno mi...
The planet-star interaction is manifested in many ways. It was found out that a close-in exoplanet causes small but measurable variability in the cores of a few lines in the spectra of several stars w...
The presence of elements heavier than helium in white dwarf atmospheres is often a signpost for the existence of rocky objects that currently or previously orbited these stars. We have measured the ab...
We report the detection of four new extrasolar planets in orbit around the moderately active stars HD 63765, HD 104067, HIP 70849, and HD 125595 with the HARPS Echelle spectrograph mounted on the ESO ...
Searching for extrasolar planets around stars of different metallicity may provide strong constraints to the models of planet formation and evolution. In this paper we present the overall results of a...
Brown Dwarf and extrasolar planet atmospheres form clouds which strongly influence the local chemistry and physics. These clouds are globally neutral obeying dust-gas charge equilibrium which is, on s...
Although our solar system features predominantly circular orbits, the exoplanets discovered so far indicate that this is the exception rather than the rule.
A picture is worth a thousand words, or so University of California, Berkeley, astronomer Paul Kalas found out when he published a Hubble Space Telescope image of a Jupiter-sized planet orbiting the s...
An All-Sky Extrasolar Planet Survey with Multiple Object, Dispersed Fixed-delay Interferometers
An All Sky Extrasolar Planet Survey with new generation multiple object Doppler instruments at Sloan telescope。
Prospects for brown dwarf and extrasolar planet research with the GTC and the LMT。
The possible belts for extrasolar planetary systems。
Extrasolar planets:theory and observations。
With the high signal-to-noise ratio spectra, we obtained Si abundances of 22 extrasolar planet host stars, and discussed some constraints on the planet formation. Using our silicon abundance results...
