On the Impact and Utility of Single-Exomoon Modeling for Multi-Moon Systems [PDF]

open access: yesarXiv
The search for exomoons in time-domain photometric data has to-date generally consisted of fitting transit models that are comprised of a planet hosting a single moon. This simple model has its advantages, but it may not be particularly representative, as most of the major moons in our Solar System are found in multi-moon satellite systems.

Determining the Eccentricity of the Moon's Orbit without a Telescope, and Some Comments on "Proof" in Empirical Science [PDF]

open access: yesarXiv, 2010
Prior to the invention of the telescope many astronomers worked out theories of the motion of the Moon. The purpose of such theories was to be able to predict the position of the Moon in the sky. These geometrical models implied a certain range of distance of the Moon.

Simulations on Levitation and Spatial Distribution of Charged Dust on the Moon Surface

open access: yesThe Planetary Science Journal
The levitation of charged dust, which may cause serious hazards to astronauts and lunar rovers, has been one of the most significant challenges in lunar exploration.

Rapid Access to Conjugated Z,Z,Z‐Trienes

open access: yesAngewandte Chemie International Edition, Accepted Article.
Intercepting reactions has recently emerged as an innovative approach in organic synthesis, allowing chemists to harness reactive intermediates to access structures and functionalities that conventional methods cannot easily achieve. By deliberately manipulating reaction pathways, this strategy provides a unique avenue to explore unusual reactivities ...

The origin of the Moon [PDF]

open access: yes
The fractionation of the chemical compositions of the moon and the earth and the thermal history of the moon for formation of the moon from an earth-orbiting swarm of bodies during the accumulation of the earth are ...

Improved Orthorectification and Empirical Reduction of Topographic Effects in Monostatic Mini-RF S-band Observations of the Moon

open access: yesThe Planetary Science Journal
The Miniature Radio Frequency instrument (Mini-RF) on the Lunar Reconnaissance Orbiter obtained widespread synthetic aperture radar observations of the Moon in the S band (12.6 cm), including nearly complete coverage at both lunar poles.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

The Eclipse of the Moon [PDF]

open access: yesNature, 1891
I VENTURE to send some notes upon last night's eclipse of the moon, taken by me here up to 11.35 p.m., when the sky became rather suddenly and entirely overcast.

Composition and Provenance of the Chang′e-6 Lunar Samples: Insights from the Simulation of the Impact Gardening Process

open access: yesThe Astrophysical Journal Letters
In 2024 June, China’s Chang′e-6 (CE-6) mission successfully returned 1935.3 grams of samples from the lunar farside for the first time. The origin and composition of the unique samples could offer valuable insights into fundamental questions on the Moon ...
