Astrospheres and Solar-like Stellar Winds [PDF]

Living Reviews in Solar Physics, 2004
Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the ...

Comic ray flux anisotropies caused by astrospheres [PDF]

Astroparticle Physics, 2016
Huge astrospheres or stellar wind bubbles influence the propagation of cosmic rays at energies up to the TeV range and can act as small-scale sinks decreasing the cosmic ray flux.

Cosmic rays in astrospheres [PDF]

Astronomy and Astrophysics, 2015
Cosmic rays passing through large astrospheres can be efficiently cooled inside these "cavities" in the interstellar medium. Moreover, the energy spectra of these energetic particles are already modulated in front of the astrospherical bow shocks.

Systematic Three-Dimensional Coculture Rapidly Recapitulates Interactions between Human Neurons and Astrocytes. [PDF]

Stem Cell Reports, 2017
© 2017 The Authors Human astrocytes network with neurons in dynamic ways that are still poorly defined. Our ability to model this relationship is hampered by the lack of relevant and convenient tools to recapitulate this complex interaction.

Mutant C9orf72 human iPSC-derived astrocytes cause non-cell autonomous motor neuron pathophysiology. [PDF]

Glia, 2020
Main points Human iPSC‐derived astrocytes harboring C9orf72 mutations recapitulate key aspects of ALS pathology and cause non‐cell autonomous pathophysiology in human iPSC‐derived motor neurons. The pathophysiology induced in motor neurons by ALS astrocytes is characterised by a progressive loss of action potential output due to a decrease in voltage ...

Astrocytes Regulate Neuronal Network Burst Frequency Through NMDA Receptors in a Species- and Donor-Specific Manner [PDF]

Biological Psychiatry Global Open Science
Background: Development of synaptic activity is a key neuronal characteristic that relies largely on interactions between neurons and astrocytes. Although astrocytes have known roles in regulating synaptic function and malfunction, the use of human- or ...

The Low-Energy Neutral Imager (LENI). [PDF]

J Geophys Res Space Phys, 2016
Abstract To achieve breakthroughs in the areas of heliospheric and magnetospheric energetic neutral atom (ENA) imaging, a new class of instruments is required. We present a high angular resolution ENA imager concept aimed at the suprathermal plasma populations with energies between 0.5 and 20 keV.

STELLA—Potential European contributions to a NASA-led interstellar probe

Frontiers in Astronomy and Space Sciences, 2022
The discovery of a myriad of exoplanets in the past decades has revolutionized the understanding of our place in the Universe. How different are exoplants and do some of them harbor life, just like Earth? To do so, their parent stars must drive a stellar

Creating a new paradigm for the local interstellar medium–A perspective

Frontiers in Astronomy and Space Sciences, 2023
The interstellar medium close to the Sun called the local ISM (LISM) provides critical insights into physical processes and phenomena in the more distant interstellar medium in our Galaxy without the confusion of many complex structures in the sight ...

INCREASE: An updated model suite to study the INfluence of Cosmic Rays on Exoplanetary AtmoSpherEs

Astronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022
Abstract Exoplanets are as diverse as they are fascinating. They vary from ultrahot Jupiter‐like low‐density planets to presumed gas‐ice‐rock mixture worlds such as GJ 1214b or worlds as LHS 1140b, which features twice the Earth's bulk density. Regarding the great diversity of exoplanetary atmospheres, much remains to be explored.
