Friends Not Foes: Strong Correlation between Inner Super-Earths and Outer Gas Giants

open access: yesThe Astrophysical Journal Letters
The connection between outer gas giants and inner super-Earths reflects their formation and evolutionary histories. Past work exploring this link has suggested a tentative positive correlation between these two populations, but these studies have been ...

Weakening Tropical West Pacific Ascent Strength Reduces East Pacific Low Clouds via Lower Free‐Tropospheric Moisture Convergence

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Low clouds (LC) are the largest source of uncertainty in the climate response to increased CO2 ${\text{CO}}_{2}$ in global climate models. This is due to the multitude of factors that affect their behavior and how these are characterized across models.

Dynamic mineral clouds on HD 189733b. II. Monte Carlo radiative transfer for 3D cloudy exoplanet atmospheres : combining scattering and emission spectra [PDF]

open access: yes, 2017
G.L. and Ch.H. highlight the financial support of the European community under the FP7 ERC starting grant 257431.Context. As the 3D spatial properties of exoplanet atmospheres are being observed in increasing detail by current and new generations of ...

The Formation of Ultra-short-period Planets under the Influence of the Nearby Planetary Companions

open access: yesThe Astrophysical Journal
Ultra-short-period (USP) planets, defined as those with orbital periods shorter than 1 day, provide valuable insights into planetary evolution under strong stellar tidal interactions.

Out There No One Has a Right to Die

open access: yesBioethics, Volume 40, Issue 6, Page 565-572, July 2026.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...

Self-consistent atmosphere modeling with cloud formation for low-mass stars and exoplanets [PDF]

open access: yes, 2017
ChH highlight financial support of the European Community under the FP7 by the ERC starting grant 257431.Context.  Low-mass stars and extrasolar planets have ultra-cool atmospheres where a rich chemistry occurs and clouds form.

Phase Equilibria of Sub-Neptunes and Super-Earths

open access: yesThe Planetary Science Journal
We investigate the consequences of nonideal chemical interaction between silicate and overlying hydrogen-rich envelopes for rocky planets using basic tenets of phase equilibria.

Orbital Migration of Protoplanets in a Marginally Gravitationally Unstable Disk. II. Migration, Merging, and Ejection

open access: yesThe Astrophysical Journal, 2023
Protoplanets formed in a marginally gravitationally unstable (MGU) disk by either core accretion or disk instability will be subject to dynamical interactions with massive spiral arms, possibly resulting in inward or outward orbital migration, mergers ...

Haze Formation in Warm H2-rich Exoplanet Atmospheres

open access: yesThe Planetary Science Journal, 2020
Abstract New observing capabilities coming online over the next few years will provide opportunities for characterization of exoplanet atmospheres. However, clouds/hazes could be present in the atmospheres of many exoplanets, muting the amplitude of spectral features.
