I present a study of the sizes (semimajor axes) of bars in disc galaxies, combining a detailed R-band study of 65 S0-Sb galaxies with the B-band measurements of...

We use data of ∼13-=000 stars from the Sloan Digital Sky Survey/Apache Point Observatory Galactic Evolution Experiment survey to study the shape of the bulge...

An optimal window for image analysis is determined by means of information theory. The size of the window is then used as a good estimator of image quality. The...

We present a different approach to determine the characteristics of the global magnetic field of the Sun based on the study of the Hanle signals. The Hanle...

The authors discuss two aspects related to the radial dependence of spatial density of interplanetary dust. First, they ask which spatial distribution the dust...

Scientific writing is an important skill for a career as a professional astrophysicist. However, very few researchers receive any formal training in how to...

Writing is a vital component of a modern career in scientific research. But how to write correctly and effectively is often not included in the training that...

Context. HR 10 has only recently been identified as a binary system. Previously thought to be an A-type shell star, it appears that both components are fast...

We present time-resolved optical spectroscopy and photometry of four relatively bright (V˜14.0-15.5) long-period cataclysmic variables (CVs) discovered in the...
