A deep insight into the ion foreshock with the help of test particle two-dimensional simulations
Lembège, Bertrand; Savoini, Philippe
Two-dimensional (2D) test particle simulations based on shock profiles issued from 2D full particle-in-cell (PIC) simulations are used in order to analyze the formation processes of ions back streaming within the upstream region after interacting with a quasi-perpendicular curved shock front. Two different types of simulations have been performed …
Equatorial Magnetosonic Waves: Do Nonlinear Interactions Play a Role in Their Evolution?
Walker, S. N.; Yearby, K. H.; Balikhin, M. A. +1 more
The occurrence of nonlinear interactions between discrete wave frequencies has been shown to play a significant role in the propagation and evolution of some plasma wave modes. In this paper we take advantage of closely spaced Cluster measurements to investigate the possibility nonlinear interactions occurring between the discrete emissions that a…
Asteroid Positions Based on the Dushanbe Part of the FON Project Observations
Andruk, V. M.; Shatokhina, S. V.; Yizhakevych, O. M. +4 more
Asteroid images identification and creation the positional catalogs based on digitized photographic observations of previous years were continued. Namely, the cooperation between Ukrainian Virtual Observatory (UkrVO) and the Institute of Astrophysics of the Academy of Sciences of Tajikistan make it possible to expand this work by involving numerou…
M Giants found in the First Byurakan Spectral Sky Survey data base. V. GAIA DR2 data
Gigoyan, K.
In this paper we study bright M {type giants found in the First Byurakan Survey (FBS) low-resolution (lr) spectroscopic data base. Phase dependence light-curves from large sky area variability data bases such as Catalina Sky Survey (CSS) and All-Sky Automated Survey for Supernovae (ASAS-SN), and the second Gaia data release data (Gaia DR2) high-qu…
Observations of Sounder Accelerated Electrons by Mars Express
Barabash, S.; Winningham, J. D.; Frahm, R. A. +5 more
The electron sensor of the Analyzer of Space Plasmas and Energetic Atoms experiment detects accelerated electrons during pulses of radio emissions from the powerful topside sounder: the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) on board the Mars Express spacecraft. Accelerated electrons are observed at energies up to 400 …
Optimized cutting off transit algorithm to study stellar rotation from PLATO mission light curves
Castro, Matthieu; de Almeida, Leandro; Anthony, Francys +4 more
Measuring the stellar rotation of one of the components in eclipsing binaries (EBs) or planetary systems is a challenge task. The difficulty is mainly due to the complexity of analyzing, in the same light curve, the signal from the stellar rotation mixed with the transit signal of a stellar or substellar companion, like a brown dwarf or planet. Th…
Spectral signature of near-surface damage in CdTe X-ray detectors
Grimm, O.
Knowledge of the response matrix of an X-ray detector is an important prerequisite for efficient use. This matrix is usually complicated due to the multitude of effects that determine the photon interaction and energy detection processes. Consequently, assembly of a response matrix often proceeds via simulation, modelling features of the detector …
Editorial: Solar Wind at the Dawn of the Parker Solar Probe and Solar Orbiter Era
Lapenta, Giovanni; van Driel-Gesztelyi, Lidia; Zhukov, Andrei
Solar Wind 15 brought together almost 250 experts from all continents of the world to discuss the current trends and future perspectives of the research on the Sun and its solar wind. The present article collection recaptures some of the highlights of their contributions.
Tidal Currents Detected in Kraken Mare Straits from Cassini VIMS Sun Glitter Observations
Sotin, Christophe; Barnes, Jason W.; Soderblom, Jason M. +3 more
We present Cassini Visual and Infrared Mapping Spectrometer (VIMS) observations of sun glitter—wave-induced reflections from a liquid surface offset from a specular point—on Kraken Mare. sun glitter reveals rough sea surfaces around Kraken Mare, namely the coasts and narrow straits. The sun glitter observations indicate wave activity driven by the…
Changes in a Dusty Ringlet in the Cassini Division after 2010
Bridges, Bill; Hedman, Mathew
A dusty ringlet designated R/2006 S3, also known as the "Charming Ringlet," is located around 119,940 km from the center of Saturn within the Laplace Gap in the Cassini Division. Prior to 2010, the ringlet had a simple radial profile and a predictable eccentric shape with two components, one forced by solar radiation pressure and the other freely …
