Non-linear quantization error reduction for the temperature measurement subsystem on-board LISA Pathfinder
Sanjuan, J.; Nofrarias, M.
Laser Interferometer Space Antenna (LISA) Pathfinder is a mission to test the technology enabling gravitational wave detection in space and to demonstrate that sub-femto-g free fall levels are possible. To do so, the distance between two free falling test masses is measured to unprecedented sensitivity by means of laser interferometry. Temperature…
Time Evolution of the Macroscopic Characteristics of a Thin Current Sheet in the Course of Its Formation in the Earth's Magnetotail
Malova, H. V.; Popov, V. Yu.; Domrin, V. I.
A numerical model is developed that allows tracing the time evolution of a current sheet from a relatively thick current configuration with isotropic distributions of the pressure and temperature in an extremely thin current sheet, which plays a key role in geomagnetic processes. Such a configuration is observed in the Earth's magnetotail in the s…
The astrometric signal of microlensing events caused by free floating planets
Nucita, Achille A.; De Paolis, Francesco; Hamolli, Lindita +1 more
Astrometric observations of microlensing events can be used to obtain important information about lenses. During these events, the shift of the position of the multiple image centroid with respect to the source star location can be measured. This effect, which is expected to occur on scales from micro-arcseconds to milli-arcseconds, depends on the…

A-type Stellar Abundances: A Corollary to Herschel Observations of Debris Disks
Matthews, Brenda; Draper, Zachary H.; Kennedy, Grant +3 more
In order to assess the relationship between metallicity and exoplanetary systems, we compare the abundances of AF-type main-sequence stars with debris disk properties assessed using Herschel observations of an unbiased survey of nearby stars. Hot stars are not as commonly observed, given their unique constraints in data reduction, lack of metal li…

Mars probe poised to solve red planet's methane mystery
Gaind, Nisha
Researchers hope European-Russian Trace Gas Orbiter will end a long-running debate over source of the gas on Mars.
A Multi-functional Paintball Cloud for Asteroid Deflection
et al.; Paek, S. W.
deweck@mit.edu2, ranohkim@gmail.com3 In this paper, the so-called “smart cloud” concept for asteroid deflection is further developed by (1) utilizing each particle as a container for paint powder and (2) deploying multiple “paintball” clouds to paint the entire surface of an asteroid. This permits deflecting an asteroid by means of a low-thrust, l…
