Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]
, 2008 The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

Ram-pressure balance surfaces for an outwardly accelerating stellar wind bow shock [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We study the problem of a stellar wind bowshock (produced by an isotropic wind/plane flowing environment interaction) that lies within the wind acceleration region in the simple, ram-pressure balance approximation. We show that this problem has a simple, approximate analytic solution that produces reasonably accurate results when applied to wind ...

THE MYSTERIOUS SICKLE OBJECT IN THE CARINA NEBULA: A STELLAR WIND INDUCED BOW SHOCK GRAZING A CLUMP? [PDF]
The Astrophysical Journal, 2013 Optical and near-infrared images of the Carina Nebula show a peculiar arc-shaped feature, which we call the "Sickle", next to the B-type star Trumpler 14 MJ 218. We use multi-wavelength observations to explore and constrain the nature and origin of the nebulosity. Using sub-mm data from APEX/LABOCA as well as Herschel far-infrared maps, we discovered a

Ks- andLp-band polarimetry on stellar and bow-shock sources in the Galactic center [PDF]
Astronomy & Astrophysics, 2013 Infrared observations of the Galactic center (GC) provide a unique opportunity to study stellar and bow-shock polarization effects in a dusty environment. The goals of this work are to present new Ks- and Lp-band polarimetry on an unprecedented number of sources in the central parsec of the GC, thereby expanding our previous results in the H- and Ks ...

Singularities in mass-loaded MHD flow: The cometary bow shock [PDF]
, 1991 We present a one-dimensional model of the mass-loading of the solar wind by cometary ions which predicts a singularity in the mass-loaded flow at M = 2. Further, a subshock occurs when the flow speed reaches M almost-equal-to 1.15.

Search for systemic mass loss in Algols with bow shocks [PDF]
, 2016 Aims. Various studies indicate that interacting binary stars of Algol type evolve non-conservatively. However, direct detections of systemic mass loss in Algols have been scarce so far.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Cometary compact H II regions are stellar-wind bow shocks
The Astrophysical Journal, 1990 Comet-shaped H II regions, like G34.3 + 0.2, are easily explained as bow shocks created by wind-blowing massive stars moving supersonically through molecular clouds. The required velocities of the stars through dense clumps are less than about 10 km/s, comparable to the velocity dispersion of stars in OB associations.

X-ray study of bow shocks in runaway stars [PDF]
, 2021 Massive runaway stars produce bow shocks through the interaction of their winds with the interstellar medium, with the prospect for particle acceleration by the shocks. These objects are consequently candidates for non-thermal emission.
