Radio Interferometric Planet Search II: Constraints on sub-Jupiter-Mass Companions to GJ 896A
Interferometric Planet Constraints sub-Jupit
2011/10/10
We present results from the Radio Interferometric Planet (RIPL) search for compan- ions to the nearby star GJ 896A. We present 11 observations over 4.9 years. Fitting astrometric parameters to the dat...
HD 46375: seismic and spectropolarimetric analysis of a young Sun hosting a Saturn-like planet
seismic spectropolarimetric analysis Saturn-like planet
2010/11/15
Context. HD 46375 is known to host a Saturn-like exoplanet orbiting at 0.04 AU from its host star. Stellar light reflected by the planet was tentatively identified in the 34-day CoRoT run acquired in ...

Retrograde Hot Jupiters Secular Planet-Planet Interactions
2010/11/15
The search for extra-solar planets has led to the surprising discovery of many Jupiter-like planets in very close proximity to their host star1, the so-called “hot Jupiters.”

Theories of planet formation predict the birth of giant planets in the inner, dense, and
gas-rich regions of the circumstellar disks around young stars. These are the regions from which strong CO emi...
An analysis of the CoRoT-2 system: A young spotted star and its inflated giant planet

CoRoT-2b is one of the most anomalously large exoplanet known. Given its large mass, its large radius cannot be explained by standard evolution models. Interestingly, the planet's parent star is an ac...
