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 ...

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 ScienceBackground: 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

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.

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 ...

The Direction of the Flow of Interstellar Neutral H Based on Photometric Observations from SOHO/SWAN
The Astrophysical Journal, 2023 Interstellar neutral hydrogen flows into the heliosphere as a mixture of the primary and secondary populations from two somewhat different directions due to splitting occurring in the magnetized outer heliosheath.

The Venusian Atmospheric Oxygen Ion Escape: Extrapolation to the Early Solar System
Journal of Geophysical Research: Planets, Volume 125, Issue 3, March 2020., 2020 Abstract The present atmosphere of Venus contains almost no water, but recent measurements indicate that in its early history, Venus had an Earth‐like ocean. Understanding how the Venusian atmosphere evolved is important not only for Venus itself but also for understanding the evolution of other planetary atmospheres.
