MAIN BELT ASTEROIDS WITH WISE/NEOWISE. I. PRELIMINARY ALBEDOS AND DIAMETERS [PDF]

open access: yes, 2011
We present initial results from the Wide-field Infrared Survey Explorer (WISE), a four-band all-sky thermal infrared survey that produces data well suited for measuring the physical properties of asteroids, and the NEOWISE enhancement to the WISE mission

Compression‐Expansion: Miniaturization, Modularity, and Logistics Beyond Earth

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT If the Cold War space race culminated in a return to Earth, at present we are experiencing a renewed interest in space. Drawing on fieldwork among people working in the space sector in Sweden, this article focuses on some of the imaginaries underpinning this resurgence and the contemporary commercialization of space. Specifically, I hone in on

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

open access: yesThe Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

Finding the aten asteroids posing potential danger for Earth

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We made the research of orbit evolutions of 321 aten asteroids on the 400 years time interval (1800–2200). We found five asteroids which come close to the Earth at a distance less than 150000 km.

The stepwise rise of angiosperm‐dominated terrestrial ecosystems

open access: yesBiological Reviews, EarlyView.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

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 N2 During Preschool: Temporal Stability and a Test of Bidirectional Effects With Maternal Emotion Characteristics in a White, European‐American Sample

open access: yesChild Development, EarlyView.
ABSTRACT Despite well‐documented behavioral changes, the development of neuropsychological substrates underlying inhibitory control remains unknown, hindering understanding of this construct over time. Stability and change in N2, a neural correlate of inhibitory control, and its crosslagged, bidirectional associations with maternal emotion ...

SEARCH SMALL BODIES IMAGES IN COLLECTIONS DIGITIZED PHOTOGRAPHIC OBSERVATIONS OF PREVIOUS YEARS

open access: yesOdessa Astronomical Publications, 2016
Photographic observations of XX century is an important source of information on small bodies of the Solar system. The observations of chronologically earlier oppositions, photometric evaluation of brightness for long periods of time allow refining the ...

Asteroids’ physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution [PDF]

open access: yes, 2013
The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and the whole asteroid population.
