Understanding the Origins of Problem Geomagnetic Storms Associated with "Stealth" Coronal Mass Ejections
Rouillard, Alexis P.; Pagano, Paolo; Nitta, Nariaki V. +14 more
Geomagnetic storms are an important aspect of space weather and can result in significant impacts on space- and ground-based assets. The majority of strong storms are associated with the passage of interplanetary coronal mass ejections (ICMEs) in the near-Earth environment. In many cases, these ICMEs can be traced back unambiguously to a specific …
Correction to: X-Ray Properties of TDEs
Komossa, S.; Jonker, P. G.; Auchettl, K. +1 more
Observational astronomy of tidal disruption events (TDEs) began with the detection of X-ray flares from quiescent galaxies during the ROSAT all-sky survey of 1990-1991. The flares complied with theoretical expectations, having high peak luminosities (Lx up to ≥4 ×1044 erg/s), a thermal spectrum with k T ∼few ×105 K…
The Location of Magnetic Reconnection at Earth's Magnetopause
Fuselier, S. A.; Trattner, K. J.; Petrinec, S. M.
One of the major questions about magnetic reconnection is how specific solar wind and interplanetary magnetic field conditions influence where reconnection occurs at the Earth's magnetopause. There are two reconnection scenarios discussed in the literature: a) anti-parallel reconnection and b) component reconnection. Early spacecraft observations …
Current Sheets, Plasmoids and Flux Ropes in the Heliosphere. Part I. 2-D or not 2-D? General and Observational Aspects
Li, Gang; Bruno, R.; Malandraki, O. +13 more
Recent accumulation of a critical mass of observational material from different spacecraft complete with the enhanced abilities of numerical methods have led to a boom of studies revealing the high complexity of processes occurring in the heliosphere. Views on the solar wind filling the interplanetary medium have dramatically developed from the be…
Geodesy, Geophysics and Fundamental Physics Investigations of the BepiColombo Mission
Cappuccio, Paolo; di Stefano, Ivan; Iess, Luciano +15 more
In preparation for the ESA/JAXA BepiColombo mission to Mercury, thematic working groups had been established for coordinating the activities within the BepiColombo Science Working Team in specific fields. Here we describe the scientific goals of the Geodesy and Geophysics Working Group (GGWG) that aims at addressing fundamental questions regarding…
Pre-flight Calibration and Near-Earth Commissioning Results of the Mercury Plasma Particle Experiment (MPPE) Onboard MMO (Mio)
Zong, Qiugang; Barabash, Stas; Bruno, Roberto +73 more
BepiColombo Mio (previously called MMO: Mercury Magnetospheric Orbiter) was successfully launched by Ariane 5 from Kourou, French Guiana on October 20, 2018. The Mercury Plasma/Particle Experiment (MPPE) is a comprehensive instrument package onboard Mio spacecraft used for plasma, high-energy particle and energetic neutral atom measurements. It co…
Gravity, Geodesy and Fundamental Physics with BepiColombo's MORE Investigation
Longo, F.; Klioner, S.; Fienga, A. +37 more
The Mercury Orbiter Radio Science Experiment (MORE) of the ESA mission BepiColombo will provide an accurate estimation of Mercury's gravity field and rotational state, improved tests of general relativity, and a novel deep space navigation system. The key experimental setup entails a highly stable, multi-frequency radio link in X and Ka band, enab…
Shock Induced Strong Substorms and Super Substorms: Preconditions and Associated Oxygen Ion Dynamics
Zong, Q. -G.; Fu, S. -Y.; Yue, C.
It is well known that the interaction between interplanetary (IP) shocks and the Earth's magnetosphere would generate/excite various types of geomagnetic phenomena. Progresses have been made on the Earth's magnetospheric response to solar wind forcing in recent years in the aspects associated with magnetospheric substorms. Strong substorms and sup…
SERENA: Particle Instrument Suite for Determining the Sun-Mercury Interaction from BepiColombo
Kallio, E.; Schmidt, W.; Barabash, S. +118 more
The ESA-JAXA BepiColombo mission to Mercury will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric particle dynamics at Mercury as well as their interactions with solar wind, solar radiation, and interplanetary dust. The particle instrument suite SERENA (Search…
BepiColombo Science Investigations During Cruise and Flybys at the Earth, Venus and Mercury
Fränz, Markus; Barabash, Stas; Krüger, Harald +59 more
The dual spacecraft mission BepiColombo is the first joint mission between the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) to explore the planet Mercury. BepiColombo was launched from Kourou (French Guiana) on October 20th, 2018, in its packed configuration including two spacecraft, a transfer module, and a sun…
