Physics News of the Week: Comet Reveals Sun’s Secrets and More

| June 9, 2013 | 0 Comments

So this week the scientist at the Polish Academy of Sciences in Warsaw gained a new understanding of the properties of materials by studying the interactions of light and the atmospheres of the big gas planets in the solar system. Meanwhile, scientists at the Lockheed Martin Advanced Technology Center in California found a way to study the region of the sun that has never been explored by any spacecrafts before. Finally, a long awaited explanation to the mysterious effects in the high temperature superconductors has been  possibly obtained by a German-French research team. As always, let’s do a short overview of these news. If you would like to receive these news and other cool stuff straight to your email, please register for our email newsletter.

1. Giant Planets Offer Help in Faster Research On Material Surfaces (June 5)

A new algorithm developed by the scientists at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, based on the mathematical formalism used to model processes accompanying interaction of light with gas planet atmospheres, is a major step towards better understanding of physical and chemical properties of materials.

“Using surface sensitive spectroscopic methods we are able to determine properties of the most external layers of materials, as well as their chemical composition or condition. This knowledge is of crucial importance in materials engineering, microelectronics, various nanotechnologies, and in so important processes as catalysis or ubiquitous corrosion,” explained Prof. Jabłoński. Read more here.

2. Comet Lovejoy Reveals Sun’s Secrets (June 7)

A comet’s close encounter with the Sun from back in 2011 has given scientists an opportunity to study a solar region that has never been visited by spacecraft. In 2011, comet Lovejoy flew deep into the Sun’s atmosphere – an area called the solar corona. Now, by studying the telescope images of the comet, scientists were able to characterize the force due to the magnetic field of the Sun, which affected the tail of the comet.

“We can’t go there because our satellites would melt, and we can’t see it because there is not much light coming from it. But comet Lovejoy gave us a means to access a part of the solar atmosphere and solar magnetic field that we cannot get into in any other way,” said Dr Karel Schrijver, from the Lockheed Martin Advanced Technology Center in California.

3. A Possible Explanation for Mysterious Effects in High-Temperature Superconductors (June 7)

A team of  German-French researchers has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. “It is not to be excluded that the new pseudogap theory also provides the long-awaited explanation for why, in contrast to conventional metallic superconductors, certain ceramic copper oxide bonds lose their electrical resistance at such unusually high temperatures,” said Prof. Dr. Konstantin Efetov and Dr. Hendrik Meier of the Chair from the Ruhr-Universität Bochum.
