"If you could put some of this superfluid in a jar it would flow up the walls of the container and over the edge," said Heinke.
Heinke says the core of the neutron star also contains a superconductor, a perfect electrical conductor. "An electric current in a superconductor never loses energy—it could keep circulating forever."
These discoveries came about when the researchers used NASA's Chanda space satellite telescope to investigate a sudden temperature drop on one particular neutron star 11,000 light years from Earth. A neutron star is the extremely dense core left behind from an exploding star, or supernova.
Heinke says this neutron star, known as the Cassiopeia A offered the researchers a great opportunity.
"It's only 330 years old," said Heinke. "We've got ringside seats to studying the life cycle of a neutron star from its collapse to its present, cooling off state."
The researchers determined that the neutron star's surface temperature is dropping because its core recently transformed into a superfluid state and is venting off heat in the form of neutrinos, sub atomic particles that flood the universe. Here on Earth our bodies are constantly bombarded by neutrinos, with 100 billion neutrinos passing harmlessly though our eyes every second.
They also found that the neutron star contains a superconductor, the highest temperature (millions of degrees) superconductor known.
This research helps us to better understand the life cycles of stars, as well as the behavior of matter at incredibly high densities.
Heinke is a co-author of the research published this month in the Monthly Notices of the Royal Astronomical Society. The research was led by Peter Shternin (St. Petersburg, Russia).

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
