Infrared Astronomical Satellite (IRAS) Scientific Data Analysis System [PDF]
The Jet Propulsion Laboratory's Scientific Data Analysis System will process Infrared Astronomical Satellite data and produce a catalog of perhaps a million infrared sources in the sky, as well as other vital information for astronomical ...

When the accreting white dwarf in a magnetic cataclysmic variable star (mCV) has a field strength in excess of 10 MG, it is expected to synchronize its rotational frequency to the binary orbit frequency, particularly at small binary separations, due to ...

The BGS magnetic field candidate models for the 12th generation IGRF [PDF]
We describe the candidate models submitted by the British Geological Survey for the 12th generation International Geomagnetic Reference Field. These models are extracted from a spherical harmonic ‘parent model’ derived from vector and scalar magnetic ...

Simulation of the Magnetic Signature for Ferromagnetic Objects in Motion Using 3D-Printing Data
Investigations of the magnetic signature for ferromagnetic objects are extremely important in many areas. Some famous software can calculate the magnetic signature generated by the 3D ferromagnetic objects in motion, but they require tremendous ...

We present a new synergic strategy that merges the potential of asteroseismology with solar space weather/climate techniques in order to characterize solar-like stars and their interaction with hosted exoplanets. The method is based on the use of seismic

Optical starlight can be partially polarized while propagating through the dusty, magnetized interstellar medium (ISM). The polarization efficiency describes the polarization intensity fraction per reddening unit, P _V / E ( B − V ), related to the ...

Damage and restoration of historical urban walls: literature review and case of studies
Within this work, the causes of collapses and damages occurred in masonry artefacts have been evaluated to properly identify suitable monitoring and restoration methods. In this regard, a comprehensive literature review has been performed.

Lithospheric long-wavelength magnetic anomalies and their geological origins: A review
At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.
