Long-term evolution of exoplanet systems
Proceedings of the International Astronomical Union, 2022 AbstractIn this Review, I discuss recent developments on the long-term dynamical evolution of exoplanet systems, focusing on how distinctive dynamical processes may have shaped the orbital architectures of observed populations. I include three applications that highlight part of my own work. First, I examine the high-eccentricity tidal migration of hot

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.

, 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 ...

Understanding exoplanet formation, structure and evolution in 2010 [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractIn this short review, we summarize our present understanding (and non-understanding) of exoplanet formation, structure and evolution, in the light of the most recent discoveries. Recent observations of transiting massive brown dwarfs seem to remarkably confirm the predicted theoretical mass-radius relationship in this domain.

The Exoplanet Population Observation Simulator. II -- Population Synthesis in the Era of Kepler [PDF]
, 2019 The collection of planetary system properties derived from large surveys such as Kepler provides critical constraints on planet formation and evolution.

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 Evolution of Atmospheric Escape of Highly Irradiated Gassy Exoplanets
Proceedings of the International Astronomical Union, 2021 AbstractAtmospheric escape has traditionally been observed using hydrogen Lyman-α transits, but more recent detections utilise the metastable helium triplet lines at 1083nm. Capable of being observed from the ground, this helium signature offers new possibilities for studying atmospheric escape.

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.

The Possible Evolution of an Exoplanet’s Atmosphere
Eos, 2021 Scientific sleuths explore data gathered trillions of kilometers away and put forth different, and often conflicting, ideas to reconstruct the gaseous envelope on a distant rocky exoplanet, GJ 1132 b.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]
Journal of Astronomy and Space Sciences, 2016 A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet
