Occurrence and core-envelope structure of 1--4x Earth-size planets around Sun-like stars [PDF]
, 2014 Small planets, 1-4x the size of Earth, are extremely common around Sun-like stars, and surprisingly so, as they are missing in our solar system. Recent detections have yielded enough information about this class of exoplanets to begin characterizing ...

Geochemistry, Geophysics, Geosystems, 2022 In prior work we found that precise approximation of the continuity constraint is crucial for accurate propagation of tracer data when advected through a background incompressible velocity field (Sime et al., 2021, https://doi.org/10.1029/2020gc009349 ...

Hot Exoplanetary Atmospheres in 3D
Remote Sensing, 2023 Hot giant exoplanets are very exotic objects with no equivalent in the Solar System that allow us to study the behavior of atmospheres under extreme conditions.

The Search for other Earths: limits on the giant planet orbits that allow habitable terrestrial planets to form [PDF]
Astrophys.J. 643 (2006) L131-L134, 2006 Gas giant planets are far easier than terrestrial planets to detect around other stars, and are thought to form much more quickly than terrestrial planets. Thus, in systems with giant planets, the late stages of terrestrial planet formation are strongly affected by the giant planets' dynamical presence. Observations of giant planet orbits may therefore

Metallicity of solar-type stars with debris discs and planets [PDF]
, 2012 Around 16% of the solar-like stars in our neighbourhood show IR-excesses due to debris discs and a fraction of them are known to host planets. We aim to determine in a homogeneous way the metallicity of a sample of stars with known debris discs and ...

Celebrating 30 years of science from the James Clerk Maxwell Telescope [PDF]
Royal Society Open Science, 2017 The James Clerk Maxwell Telescope (JCMT) has been the world’s most successful single-dish telescope at submillimetre wavelengths since it began operations in 1987. From the pioneering days of single-element photometers and mixers, through to the state-of-

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.

The Astrophysical Journal, 2014 Hot Jupiters formed through circularization of high-eccentricity orbits should be found at orbital separations $a$ exceeding $twice$ that of their Roche limit $a_{\rm R}$. Nevertheless, about a dozen giant planets have now been found well within this limit ($a_{\rm R}

About the Foroughi Cup and about the seven planets in the Ancient World [PDF]
Archaeoastronomy and Ancient Technologies, 2018 The Foroughi Cup is an artefact of the 8th century BC of Aramaic cultural context, inside which images of stars and constellations are reproduced. In this study of ours we start from the conclusions reached by Amadasi Guzzo and Castellani in their two ...

The California-Kepler Survey. I. High-resolution Spectroscopy of 1305 Stars Hosting Kepler Transiting Planets [PDF]
, 2017 The California-Kepler Survey (CKS) is an observational program developed to improve our knowledge of the properties of stars found to host transiting planets by NASA’s Kepler Mission.
