A simple model for H-2 line profiles in bow shocks [PDF]

, 2005
We present a model for empirically reproducing line profiles of molecular hydrogen emission in bow shocks. The model takes into account bow velocity, dissociation limit, a cooling function, viewing angle, bow shape and a limited form of extinction.

The IMF Clock Angle Effect on the Tail Cross Section of the Martian Magnetic Pileup Boundary and Bow Shock

The Astrophysical Journal
Using a three-dimensional global magnetohydrodynamic (MHD) simulation model, we investigate the effects of different interplanetary magnetic field (IMF) clock angles on the tail configuration of the Martian magnetic pileup boundary (MPB) and bow shock ...

Hunger as an uncontroversial predictor of poor adolescent mental health: evidence from a multiverse analysis of 410,213 adolescents across 79 countries

Journal of Child Psychology and Psychiatry, Volume 67, Issue 10, Page 1741-1751, October 2026.
Background Hunger has established detrimental impacts on physical health, with emerging evidence indicating negative impacts on mental health. However, there is a pronounced knowledge gap outside high‐income settings and for adolescents. Previous research also provides differing estimates of hunger's impacts, potentially underpinned by a wide range of ...

Evaluating planetesimal bow shocks as sites for chondrule formation

, 2004
We investigate the possible formation of chondrules by planetesimal bow shocks. The formation of such shocks is modeled using a piecewise parabolic method (PPM) code under a variety of conditions.

Predictions of the solar wind interaction with Comet Grigg-Skjellerup [PDF]

, 1992
The planned encounter of the Giotto spacecraft with comet Grigg-Skjellerup on 10th July 1992 promises to extend our knowledge of the solar wind interaction with comets substantially.

Wideband loaded wire bow-tie antenna for near field imaging using genetic algorithms [PDF]

, 2008
YesThe potentially broad application area in engineering design using Genetic Al- gorithm (GA) has been widely adopted by many researchers due to its high consistency and accuracy.

SDSO 1 is a Shocked Ghost Planetary Nebula in Front of M 31

The Astrophysical Journal
We present new, deep narrowband imagery and discuss the nature of SDSO 1, the large [O iii ]-emitting nebula centered $1\mathop{.}\limits^{^\circ }5$ SE of M 31.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]

The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.
