Dynamo Models for Planets Other Than EarthSpace Science Reviews - Tập 152 - Trang 617-649 - 2009
Sabine Stanley, Gary A. Glatzmaier
Observations from planetary spacecraft missions have demonstrated a spectrum of
dynamo behaviour in planets. From currently active dynamos, to remanent crustal
fields from past dynamo action, to no observed magnetization, the planets and
moons in our solar system offer magnetic clues to their interior structure and
evolution. Here we review numerical dynamo simulations for planets other than

Das thermische plasma als intensitäts normalstrahler im wellenlängenbereich von 1100 bis 3100 åSpace Science Reviews - Tập 11 - Trang 728-772 - 1970
G. Boldt
In this paper a standard intensity source is described consisting of a thermal
argon plasma with small additives of hydrogen, nitrogen, and carbon dioxide.
These gases are introduced in such a concentration to produce a series of
optically thick spectral lines in the region 1100 Å to 3100 Å. The intensity in
an optically thick line center is given by the Kirchhoff-Planck-function Bλ (T)
which is d... hiện toàn bộ
Small-Scale Dynamos: From Idealized Models to Solar and Stellar ApplicationsSpace Science Reviews - Tập 219 - Trang 1-45 - 2023
Matthias Rempel, Tanayveer Bhatia, Luis Bellot Rubio, Maarit J. Korpi-Lagg
In this article we review small-scale dynamo processes that are responsible for
magnetic field generation on scales comparable to and smaller than the energy
carrying scales of turbulence. We provide a review of critical observation of
quiet Sun magnetism, which have provided strong support for the operation of a
small-scale dynamo in the solar photosphere and convection zone. After a review
of ba... hiện toàn bộ
Peculiar SupernovaeSpace Science Reviews - Tập 214 - Trang 1-25 - 2018
Dan Milisavljevic, Raffaella Margutti
What makes a supernova truly “peculiar?” In this review we attempt to address
this question by tracing the history of the use of “peculiar” as a descriptor of
non-standard supernovae back to the original binary spectroscopic classification
of Type I vs. Type II proposed by Minkowski (Publ. Astron. Soc. Pac., 53:224,
1941). A handful of noteworthy examples are highlighted to illustrate a general

Lunar Reconnaissance Orbiter Camera (LROC) Instrument OverviewSpace Science Reviews - Tập 150 - Trang 81-124 - 2010

Malin, P. Mahanti, A. Bartels, J. Anderson, T. N. Tran, E. M. Eliason, A. S. McEwen, E. Turtle, B. L. Jolliff, H. Hiesinger
The Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) and
Narrow Angle Cameras (NACs) are on the NASA Lunar Reconnaissance Orbiter (LRO).
The WAC is a 7-color push-frame camera (100 and 400 m/pixel visible and UV,
respectively), while the two NACs are monochrome narrow-angle linescan imagers
(0.5 m/pixel). The primary mission of LRO is to obtain measurements of the Moon
that will ... hiện toàn bộ
Deducing Electron Properties from Hard X-ray ObservationsSpace Science Reviews - Tập 159 - Trang 301-355 - 2011

X-radiation from energetic electrons is the prime diagnostic of
flare-accelerated electrons. The observed X-ray flux (and polarization state) is
fundamentally a convolution of the cross-section for the hard X-ray emission
process(es) in question with the electron distribution function, which is in
turn a function of energy, direction, spatial location and time. To address the
problems of particle ... hiện toàn bộ
Halo White Dwarfs and Baryonic Dark MatterSpace Science Reviews - - 1998
B.D. Fields, G.J. Mathews, D.N. Schramm
We describe the formation of hot intergalactic gas along with baryonic remnants
in galaxy halos. In this scenario, the mass and metallicity of the hot
intracluster and intragroup gas relates directly to the production of baryonic
remnants during the collapse of galactic halos. We construct a schematic but
self-consistent model in which early bursts of star formation lead to a large
remnant populat... hiện toàn bộ
Tidal Dissipation in Giant PlanetsSpace Science Reviews - - 2024
Jim Fuller, T. Guillot, S. Mathis, C. D. Murray
AbstractTidal interactions between moons and planets can have major effects on
the orbits, spins, and thermal evolution of the moons. In the Saturn system,
tidal dissipation in the planet transfers angular momentum from Saturn to the
moons, causing them to migrate outwards. The rate of migration is determined by
the mechanism of dissipation within the planet, which is closely tied to the
planet’s ... hiện toàn bộ

Gérard, Benoit Hubert, Joseph D. Huba, Robert R. Meier, Bryce Roberts
The two-year prime mission of the NASA Ionospheric Connection Explorer (ICON) is
complete. The baseline operational and scientific objectives have been met and
exceeded, as detailed in this report. In October of 2019, ICON was launched into
an orbit that provides its instruments the capability to deliver near-continuous
measurements of the densest plasma in Earth’s space environment. Through
