New ultraviolet observations indicate a Milky Way star is spinning nearly 200 times faster than Earth’s sun, the probable result of a merger between two sun-like stars whose binary orbit recently collapsed, according to a University of Colorado at Boulder astronomer.
The yellow giant, known as FK Comae Berenices, or FK Com, is 10 times larger than the sun and is emitting spectacular amounts of X-rays, ultraviolet light and radio waves as it rotates furiously, said Senior Research Associate Thomas Ayres of CU-Boulder’s Center for Astrophysics and Space Astronomy.
Dubbed the "King of Spin" by the research team, FK Com is the namesake of a rare class of fast-rotating yellow giants noted for high levels of coronal magnetic activity, said Ayres. "FK Com objects are oddballs because most giant stars rotate very slowly. That’s why many theorists now believe binary mergers are the best way to explain the existence of these rare, ultra-fast rotators," he said.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
