An introductory review of the thermal structure of subduction zones: I—motivation and selected examples

Progress in Earth and Planetary Science, 2023
The thermal structure of subduction zones is fundamental to our understanding of physical and chemical processes that occur at active convergent plate margins.

Eccentricity Evolution of Extrasolar Multiple Planetary Systems due to the Depletion of Nascent Protostellar Disks

, 2002
Most extrasolar planets are observed to have eccentricities much larger than those in the solar system. Some of these planets have sibling planets, with comparable masses, orbiting around the same host stars.

The effects of fly-bys on planetary systems [PDF]

, 2010
Most of the observed extrasolar planets are found on tight and often eccentric orbits. The high eccentricities are not easily explained by planet-formation models, which predict that planets should be on rather circular orbits.

THE OCCURRENCE OF POTENTIALLY HABITABLE PLANETS ORBITING M DWARFS ESTIMATED FROM THE FULL KEPLER DATASET AND AN EMPIRICAL MEASUREMENT OF THE DETECTION SENSITIVITY [PDF]

, 2015
We present an improved estimate of the occurrence rate of small planets orbiting small stars by searching the full four-year Kepler data set for transiting planets using our own planet detection pipeline and conducting transit injection and recovery ...

Habitable Moist Atmospheres on Terrestrial Planets near the Inner Edge of the Habitable Zone around M Dwarfs [PDF]

, 2017
Terrestrial planets in the habitable zones (HZs) of low-mass stars and cool dwarfs have received significant scrutiny recently. Transit spectroscopy of such planets with the James Webb Space Telescope (JWST) represents our best shot at obtaining the ...

Imaging Extrasolar Giant Planets [PDF]

, 2016
High-contrast adaptive optics (AO) imaging is a powerful technique to probe the architectures of planetary systems from the outside-in and survey the atmospheres of self-luminous giant planets.

Survival of habitable planets in unstable planetary systems

, 2016
Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces these scatterings may also cause habitable planets in interior orbits to ...

275 Candidates and 149 Validated Planets Orbiting Bright Stars in K2 Campaigns 0–10 [PDF]

, 2018
Since 2014, NASA’s K2 mission has observed large portions of the ecliptic plane in search of transiting planets and has detected hundreds of planet candidates.

Radial Migration of Gap-opening Planets in Protoplanetary Disks. I. The Case of a Single Planet [PDF]

Astrophysical Journal, 2018
A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk–planet interaction and migrates with the gap in the disk.
