Hot flow anomalies at Venus [PDF]

Journal of Geophysical Research, 2012
We present a multi‐instrument study of a hot flow anomaly (HFA) observed by the Venus Express spacecraft in the Venusian foreshock, on 22 March 2008, incorporating both Venus Express Magnetometer and Analyzer of Space Plasmas and Energetic Atoms (ASPERA) plasma observations.

A survey of hot flow anomalies at Venus [PDF]

Journal of Geophysical Research: Space Physics, 2014
We present the first survey of hot flow anomalies (HFAs) at the bow shock of Venus, expanding on our recent initial case study. A 3.06 sol (774 Earth day) survey of Venus Express magnetometer, ion spectrometer, and electron spectrometer data was undertaken in order to identify Cytherian HFAs. Seven events were discovered, corresponding to a statistical

Hot flow anomalies at Saturn's bow shock [PDF]

Journal of Geophysical Research, 2009
We present evidence for the occurrence of hot flow anomalies (HFAs) at Saturn's bow shock. A survey of Cassini magnetic field and electron data taken upstream of the dawn flank bow shock is carried out in order to identify Kronian HFAs. Seventeen events are identified that were all associated with energization of the solar wind electrons and satisfied ...

THEMIS satellite observations of hot flow anomalies at Earth's bow shock [PDF]

Annales Geophysicae, 2017
Hot flow anomalies (HFAs) at Earth's bow shock were identified in Time History of Events and Macroscale Interactions During Substorms (THEMIS) satellite data from 2007 to 2009.

Formation of hot flow anomalies and solitary shocks [PDF]

Journal of Geophysical Research, 2007
Interaction of a tangential discontinuity (TD) with the bow shock is investigated by using electromagnetic, global hybrid simulations in which ions are treated kinetically via particle‐in‐cell methods and electrons form a massless fluid. On the basis of previous studies, it was expected that the interaction would result in the formation of a hot flow ...

The Evolution of Hot Flow Anomalies in Martian Space Environment

Geophysical Research Letters
Hot Flow Anomalies (HFAs) are transient foreshock structures generated by solar wind discontinuity‐bow shock interactions, with their evolution only confirmed near Earth.

Origin and evolution of fluids and heatflow in geothermal systems of Indus River Basin (IRB), India [PDF]

Scientific Reports
The Himalayan–Tibetan Orogeny, driven by the convergence of the Indian and Eurasian plates, has resulted in significant crustal thickening, intense deformation and widespread magmatism.

Statistical properties of hot flow anomalies around Mars

Earth and Planetary Physics
Hot flow anomalies (HFAs) are not only a terrestrial phenomenon, but also a solar-system-wide phenomenon, one that can cause significant perturbations in planetary magnetospheres and ionospheres.

A statistical study of hot flow anomalies using Cluster data [PDF]

Advances in Space Research, 2008
Hot flow anomalies (HFAs) are studied using observations of the RAPID suprathermal charged particle detector, the FGM magnetometer, and the CIS plasma detector aboard the four Cluster spacecraft. Previously, we studied several specific features of tangential discontinuities on the basis of Cluster measurements in February-April 2003.

Case and statistical studies on the evolution of hot flow anomalies [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractHot flow anomalies (HFAs) frequently observed near Earth's bow shock are phenomena resulting from the interaction between interplanetary discontinuities and Earth's bow shock. We identify 199 HFA events using Cluster data from 2001 to 2010 and divide these events into four categories according to the dynamic pressure profile, namely, “−+,” “+−,”
