The orbital evolution of dust particles initially located outside the equatorial plane is considered. The averaging method is used to solve equations of motion...
Mid-infrared spectrum of the zodiacal light observed with ISOPHOT
We present 29 mid-infrared spectra of the zodiacal light distributed over the sky. The observed 5.9-11.7 mu m spectral shapes are well represented by blackbody...
No Evidence for Critical Balance in Field-aligned Alfvénic Solar Wind Turbulence
The properties of Alfvénic solar wind turbulence have been studied for decades using spacecraft measurements. In particular, the observation of spectral...
Non-grey dimming events of KIC 8462852 from GTC spectrophotometry
We report ground-based spectrophotometry of KIC 8462852 obtained during its first dimming events since the end of the Kepler mission. The dimmings show a clear...
The Planck satellite provides a set of all-sky maps at nine frequencies from 30 GHz to 857 GHz. Planets, minor bodies, and diffuse interplanetary dust emission...
Radiation-induced forces on the orbits of dust particles around rotating stars
The influence of rotation and finite size of the radiation source on the orbits of dust particles around stars is analyzed. It is found that there are physical...
Tabbys Stern - sind die mysteriösen Helligkeitsschwankungen geklärt?
Eine der rätselhaftesten astronomischen Entdeckungen der letzten Jahre waren die seltsamen Helligkeitsschwankungen des Sterns KIC 8462852 in den Daten des...
Zodiacal light photopolarimetry. I - Observations, reductions, disturbing phenomena, accuracy. II - Gradients along the ecliptic and the phase functions of interplanetary matter
