On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]
, 2015 PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).

Revised Mass and Orbit of ε Eridani b: A 1 MJup Planet on a Near-circular Orbit
The Astronomical JournalThe mature Jovian planet ε Eridani b ( ε Eri b) orbits one of the closest Sun-like stars at a moderate separation of 3.5 au, presenting one of the best opportunities to image a true analog to a solar system planet.

Spectropolarimetric signatures of Earth-like extrasolar planets
, 2007 We present results of numerical simulations of flux F and degree of polarization P of light that is reflected by Earth–like extrasolar planets orbiting solar type stars. Our results are presented as functions of the wavelength (from 0.3 to 1.0 ?m, with 0.

Single-mode fiber length for wavefront filtering
, 2008 Stellar nulling interferometry offers the possibility of direct imaging of extrasolar planets necessary for the detection of extra-terrestrial life. Achieving optimum performance from the interferometers requires that the wavefronts of light reaching the

Migration and Extrasolar Terrestrial Planets: Watering the Planets
, 2012 International audienceSimulations of the compositions of extrasolar terrestrial planets have shown that migration of giant planets assists in producing "Earth-like" terrestrial planets and delivering water and other volatiles to terrestrial planets ...

Life at the end of worlds : modelling the biosignatures of microbial life in diverse environments at the end of the habitable lifetimes of Earth-like planets [PDF]
, 2014 This thesis investigates how increased global mean temperatures on Earth, induced by the increase in the luminosity of the Sun as it ages, change the types of habitable environments on the planet at local scales over the next 3 Gyr.

Discovery and Dynamics of the Nontransiting Planet Kepler-139f
The Astrophysical Journal LettersAmong the ways that an outer giant planet can alter the architecture of an inner planetary system is by tilting the orbits of the inner planets and reducing their mutual transit probabilities.

Characterization of Extrasolar Planets Using SOFIA [PDF]
, 2010 Topics include: the landscape of extrasolar planets, why focus on transiting planets, some history and Spitzer results, problems in atmospheric structure or hot Jupiters and hot super Earths, what observations are needed to make progress, and what SOFIA ...

The Gap–Giant Association: Are Planets Hiding in the Gaps?
The Astrophysical JournalA handful of stars are known to host both an inner system of multiple transiting planets and an outer giant planet. These systems all feature a prominent gap between the orbits of two of the transiting planets, distinguishing them from typical ...
