Adaptive Optics and Star Formation
In this contribution I will briefly review the growing impact adaptive optics is having on the field of star formation. The volume of interesting... -
The Accelerating Universe and Dark Energy: Evidence from Type Ia Supernovae
I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance determinations. Low-redshift SNe Ia (... -
Astronomy in the Andes
The Andean peoples lived in a world that they considered to be animated by natural but also supernatural forces. These forces were believed to be... -
Dynamics of young stellar clusters as planet-forming environments
Most stars and thus most planetary systems do not form in isolation. The larger star-forming environment affects protoplanetary disks in multiple...

Dynamics and clouds in planetary atmospheres from telescopic observations
This review presents an insight into our current knowledge of the atmospheres of the planets Venus, Mars, Jupiter, Saturn, Uranus and Neptune, the...

Star-Forming Regions
Since the 1980s, the Einstein Observatory has shown that the Young Stellar Objects (YSOs) emit X-rays with luminosities, in the 0.3–8 keV bandpass,... -
Ultraviolet spectropolarimetry with polstar: interstellar medium science
Continuum polarization over the UV-to-microwave range is due to dichroic extinction (or emission) by asymmetric, aligned dust grains. Scattering can...

Earth=Venus, part II: future Earth?
A review of the Earth’s history; ancient climate records; continents and climate, little ice ages; migrating habitable zones and... -
Chemical Enrichment in Groups and Clusters
As building blocks of dust, rocky planets, and even complex life, the chemical elements heavier than hydrogen (H) and helium (He) – called “metals”... -
The Plasma Environment of Comet 67P/Churyumov-Gerasimenko
The environment of a comet is a fascinating and unique laboratory to study plasma processes and the formation of structures such as shocks and...

The Early History of Heliospheric Science and the Spacecraft That Made It Possible
Our understanding of the interaction of the large-scale heliosphere with the local interstellar medium (LISM) has undergone a profound change since...

In Situ Observations of Interstellar Pickup Ions from 1 au to the Outer Heliosphere
Interstellar pickup ions are an ubiquitous and thermodynamically important component of the solar wind plasma in the heliosphere. These PUIs are born...

Planetesimal rings as the cause of the Solar System’s planetary architecture
Astronomical observations reveal that protoplanetary disks around young stars commonly have ring- and gap-like structures in their dust...

Final Stages of Luminous Stars
In this chapter, we take a step further and discuss the star developmentstar development beyond the initial state. Figure 5.1 gives us an overview.... -
Interplanetary Dust, Meteoroids, Meteors and Meteorites
Interplanetary dust particles and meteoroids mostly originate from comets and asteroids. Understanding their distribution in the Solar system, their...

Inversion algorithm for non-spherical dust particle size distributions
Dust particles are the main aerosol component of the atmosphere, and can influence human, environmental, and ecological health. Particle size...

Flickering Candles: Cepheid Variable Stars
Cepheid variable stars change their intrinsic luminosity in a Cepheid variablespecific manner with periods ranging from days to months. In the early... -
Stellar flares
Magnetic storms on stars manifest as remarkable, randomly occurring changes of the luminosity over durations that are tiny in comparison to the...

The Evolution of Galaxies and Active Galaxies with Cosmic Epoch
Evolutionary changes in the properties of all classes of extragalactic systems with cosmic epoch have been observed in all accessible astronomical... -
Surface Compositions of Trojan Asteroids
The Jupiter Trojan asteroids are a key population for understanding the chemical and dynamical evolution of the Solar System. Surface compositions of...
