Exoplanet status report: Observation, characterization and evolution of exoplanets and their host stars

Solar System Research, 2010
After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science during the past decade. The characterization of exoplanets can only be carried out in a well coordinated interdisciplinary way which connects ...

The Habitable Zone and Extreme Planetary Orbits [PDF]

, 2012
The Habitable Zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties.

A Stellar Mass Dependence of Structured Disks: A Possible Link with Exoplanet Demographics [PDF]

, 2021
Gaps in protoplanetary disks have long been hailed as signposts of planet formation. However, a direct link between exoplanets and disks remains hard to identify.

The evolution of hot Jupiters revealed by the age distribution of their host stars. [PDF]

Proc Natl Acad Sci U S A, 2023
Significance Hot Jupiters are the first exoplanet population discovered around main-sequence stars. However, their origin and evolution remain puzzled.

Tidal Evolution of Exoplanets

, 2010
Tidal effects arise from differential and inelastic deformation of a planet by a perturbing body. The continuous action of tides modify the rotation of the planet together with its orbit until an equilibrium situation is reached. It is often believed that synchronous motion is the most probable outcome of the tidal evolution process, since synchronous ...

A Search for wide visual companions of exoplanet host stars - The Calar Alto Survey [PDF]

, 2006
We have carried out a search for co-moving stellar and substellar companions around 18 exoplanet host stars with the infrared camera MAGIC at the 2.2m Calar Alto telescope, by comparing our images with images from the all sky surveys 2MASS, POSS I and II.
