A Reanalysis of the Composition of K2-106b: An Ultra-short-period Super-Mercury Candidate

open access: yesThe Astronomical Journal, 2023
We present a reanalysis of the K2-106 transiting planetary system, with a focus on the composition of K2-106b, an ultra-short-period, super-Mercury candidate. We globally model existing photometric and radial velocity data and derive a planetary mass and

How terrestrial planets traverse spin-orbit resonances: A camel goes through a needle's eye

open access: yes, 2012
The dynamical evolution of terrestrial planets resembling Mercury in the vicinity of spin-orbit resonances is investigated using comprehensive harmonic expansions of the tidal torque taking into account the frequency-dependent quality factors and Love ...

An Eastward Current Encircling Mercury

open access: yesGeophysical Research Letters, 2022
Mercury has a terrestrial‐like magnetosphere which is usually taken as a scaled‐down‐version of Earth's magnetosphere with a similar current system. We examine Mercury's magnetospheric current system based on a survey of Mercury's magnetic field measured

Selective Aggregation Experiments on Planetesimal Formation and Mercury-Like Planets

open access: yesGeosciences, 2018
Much of a planet’s composition could be determined right at the onset of formation. Laboratory experiments can constrain these early steps. This includes static tensile strength measurements or collisions carried out under Earth’s gravity and

Estimation of a planetary magnetic field using a reduced magnetohydrodynamic model [PDF]

open access: yesAnnales Geophysicae, 2017
Knowledge of planetary magnetic fields provides deep insights into the structure and dynamics of planets. Due to the interaction of a planet with the solar wind plasma, a rather complex magnetic environment is generated.

Addressing the statistical mechanics of planet orbits in the solar system

open access: yes, 2017
The chaotic nature of planet dynamics in the solar system suggests the relevance of a statistical approach to planetary orbits. In such a statistical description, the time-dependent position and velocity of the planets are replaced by the probability ...

Evolution of Mercury’s Volatile-bearing Crust within Raditladi Basin

open access: yesThe Planetary Science Journal
Mercury’s surface presents significant challenges for understanding planetary volatile distribution. Previous studies have identified features including hollows, flows, and chaotic terrains as associated with the presence of volatiles.

Water Group Exospheres and Surface Interactions on the Moon, Mercury, and Ceres

open access: yesSpace Science Reviews, 2021
Water ice, abundant in the outer solar system, is volatile in the inner solar system. On the largest airless bodies of the inner solar system (Mercury, the Moon, Ceres), water can be an exospheric species but also occurs in its condensed form.

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.
