Virility, fascism and regeneration in post‐Civil War Spain: On interpretations of literary Romanticism under the Franco regime

open access: yesGender &History, EarlyView.
Abstract In the years immediately following the Spanish Civil War, the political culture of Falangism developed a deeply gendered regenerationist discourse, which proposed that regeneration would only be possible if the nation recovered its virile attributes.

Comparative Mid-infrared Spectroscopy of Dark, Primitive Asteroids: Does Shared Taxonomic Class Indicate Shared Silicate Composition?

open access: yesThe Planetary Science Journal
Primitive asteroids with low albedos and red slopes in the visible and near-infrared (VNIR) are found in both the main belt and the Jupiter Trojan clouds.

The distribution of asteroids: evidence from Antarctic micrometeorites [PDF]

open access: yes, 2002
The relative abundances of types amongst 550 AMMs are reported. These suggest that C-type asteroids vary from petrologic type 1 to 3.2 and that the majority of S-type asteroids are chondrule ...

A Comparative Study of Infrared Asteroid Surveys: IRAS, AKARI, and WISE

open access: yes, 2014
We present a comparative study of three infrared asteroid surveys based on the size and albedo data from the Infrared Astronomical Satellite (IRAS), the Japanese infrared satellite AKARI, and the Wide-field Infrared Survey Explorer (WISE).

EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

open access: yesGlobal Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

On the Border: Searching for Cometary Activity near the Centaur–JFC Transition Line

open access: yesThe Planetary Science Journal
Current wide-field surveys discover ∼15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover many asteroids that have distant JFC-like orbits, but with no reported ...

Determination of Orbital Elements and Ephemerides using the Geocentric Laplace’s Method

open access: yesJournal of Astronomy and Space Sciences, 2020
This paper presents a methodology for Initial Orbit Determination (IOD) based on a modification of the Laplace’s geocentric method. The orbital elements for Near-Earth asteroids (1864) Daedalus, 2003 GW, 2019 JA8, a Hungaria-type asteroid (4690 ...

Measuring the Orbit Drift of Near-Earth Asteroids by the Yarkovsky Effect

open access: yesThe Astrophysical Journal, 2023
The Yarkovsky effect causes the semimajor axis drift of near-Earth asteroids. The drift can be detected by a precise orbit determination process. Using the proposed algorithm, 2233 out of 27,078 near-Earth asteroids are chosen as the initial candidates ...
