A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Rethinking “Prebiotic Chemistry”

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract In origins‐of‐life research, the term “prebiotic chemistry” is commonly used to describe processes thought to be related to or required for the emergence of life. However, it suffers from several potential drawbacks that have caused the present group of authors to rethink their usage of the term.

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

The rotation and Galactic kinematics of mid M dwarfs in the Solar Neighborhood

open access: yes, 2015
Rotation is a directly-observable stellar property, and drives magnetic field generation and activity through a magnetic dynamo. Main sequence stars with masses below approximately 0.35Msun (mid-to-late M dwarfs) are fully-convective, and are expected to

The Roads Traveled to Reach a Greenhouse Gas Flux Network

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Flux measurements of greenhouse gases provide information on the metabolic activity of ecosystems. And they are useful for parameterizing and validating remote sensing and biogeochemical models that are used to assess water and carbon fluxes across space and time.

Evry Leon Schatzman

open access: yes, 2014
This article describes the life and work of French astrophysicist Evry Schatzman (1920-2010). He was a pioneer in the study of white dwarfs during the 1940s and was one of the proponents of the wave heating theory of the solar corona.

Nuclear-Astrophysics Lessons from INTEGRAL

open access: yes, 2013
Measurements of high-energy photons from cosmic sources of nuclear radiation through ESA's INTEGRAL mission have advanced our knowledge: New data with high spectral resolution showed that characteristic gamma-ray lines from radioactive decays occur ...

An Asymmetric Galactic Stellar Disk Traced by OB-type Stars from LAMOST DR7

open access: yesResearch in Astronomy and Astrophysics
Using 9943 OB-type stars from LAMOST DR7 in the solar neighborhood, we fit the vertical stellar density profile with the model including a single exponential distribution at different positions (R, Φ).

Breaking Down the Wall That Historically Separates the Atmosphere, Ionosphere, and Magnetosphere (AIM) Communities: AGU Chapman Conference on AIM Coupling

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract This meeting report summarizes outcomes from the AGU Chapman Conference on Particle Precipitation: Drivers, Properties, and Impacts on Atmosphere, Ionosphere, Magnetosphere (AIM) Coupling, held 14–21 February 2025, in Melbourne, Australia. This conference brought together scientists from around the world to identify pressing AIM open science ...

The Effective Temperatures of O-type Stars from UV spectroscopy

open access: yes, 2013
We present an analysis of high resolution spectra in the far-UV -- UV range (~905-2000\AA) with non-LTE, spherical, hydrodynamical, line-blanketed models, of three O-type Galactic stars, and derive their photospheric and wind parameters.
