Shock excitation of the knots of Hen 3-1475 [PDF]

open access: yes, 2006
We present new optical STIS HST spectroscopic observations of the jets of the proto-planetary nebula Hen 3-1475. The excitation conditions of the knots of Hen 3-1475 are derived from the observed optical spectra, confirming that the knots are shock ...

Pulsar bow-shock nebulae [PDF]

open access: yesAstronomy & Astrophysics, 2001
Pulsar bow-shock nebulae originate from the interaction of the ambient medium with the wind of a moving pulsar. The properties of these nebulae depend on both the physical conditions in the ambient medium and the characteristics of the pulsar wind, and may thus represent a powerful diagnostic tool.

E-BOSS: an Extensive stellar BOw Shock Survey. I: Methods and First Catalogue [PDF]

open access: yes, 2011
Context: Bow shocks are produced by many astrophysical objects where shock waves are present. Stellar bow shocks, generated by runaway stars, have been previously detected in small numbers and well-studied.

E-BOSS: An Extensive stellar BOw Shock Survey. II. Catalogue second release [PDF]

open access: yes, 2015
Context. Stellar bow shocks have been studied not only observationally, but also theoretically since the late 1980s. Only a few catalogues of them exist.

MESSENGER Observations of Standing Whistler Waves Upstream of Mercury's Bow Shock

open access: yesGeophysical Research Letters, 2023
This paper reports on the standing whistler waves upstream of Mercury's quasi‐perpendicular bow shock. Using MESSENGER's magnetometer data, 36 wave events were identified during interplanetary coronal mass ejections (ICMEs).

Emission from Bow Shocks of Beamed Gamma-Ray Bursts [PDF]

open access: yes, 2000
Beamed gamma-ray burst (GRB) sources produce a bow shock in their gaseous environment. The emitted flux from this bow shock may dominate over the direct emission from the jet for lines of sight which are outside the angular radius of the jet emission ...

Systematic search for high-energy gamma-ray emission from bow shocks of runaway stars [PDF]

open access: yes, 2014
Context. It has been suggested that the bow shocks of runaway stars are sources of high-energy gamma rays (E > 100 MeV). Theoretical models predicting high-energy gamma-ray emission from these sources were followed by the first detection of non-thermal ...

Modeling non-thermal emission from stellar bow shocks [PDF]

open access: yes, 2016
Runaway O- and early B-type stars passing throughout the interstellar medium at supersonic velocities and characterized by strong stellar winds may produce bow shocks that can serve as particle acceleration sites.

Bow shock motions observed with CLUSTER [PDF]

open access: yesGeophysical Research Letters, 2003
The Cluster mission allows the determination not only of the bow shock crossing position but also, with a simple timing method and a reasonable confidence, the shock normal and the velocity along this normal. We apply this technique to a series of eleven consecutive bow shock crossings which occurred during a time interval of approximatively two and a ...

MeV magnetosheath ions energized at the bow shock [PDF]

open access: yes, 2001
A causal relationship between midlatitude magnetosheath energetic ions and bow shock magnetic geometry was previously established for ion energy up to 200 keV e−1 for the May 4, 1998, storm event.
