Queen's researchers discover magnetic field in Polaris, the North Star

Astronomers at Queen카지노 게임 컬렉션�s 카지노게임사이트 in Kingston have discovered for the first time that Polaris 카지노 게임 컬렉션� more commonly known as the North Star 카지노 게임 컬렉션� is host to a remarkable magnetic field. Polaris is a member of a class of pulsating stars called the classical Cepheids and pulsates over a four day period during which its diameter, temperature, and brightness change. Little is known about the influence of magnetic fields on Cepheid behaviour and evolution, as their magnetic fields have been very difficult to detect. This is a first for Polaris and only the second for any Cepheid.

The discovery was made by Queen카지노 게임 컬렉션�s PhD candidate James Barron (Physics, Engineering Physics and Astronomy) who is leading a team of Canadian and international astronomers in exploring the magnetism of the classical Cepheids. It was during an observing run at the Canada-France-Hawaii Telescope (CFHT) on Mauna Kea, Hawaii that Barron discovered the magnetic field.

카지노 게임 컬렉션�I was analyzing the data that had been obtained the night before and I was excited to see that Polaris카지노 게임 컬렉션� magnetic field had been observed. The signal is detected very clearly,카지노 게임 컬렉션� says Barron.

Barron and his team plan to develop a map of its magnetic field by taking many more observations as the star rotates.

카지노 게임 컬렉션�This will provide the first view of the global magnetic structure of any Cepheid, and will serve as the basis for a deeper theoretical understanding of the role of magnetic fields in Cepheid evolution and behaviour,카지노 게임 컬렉션� says Gregg Wade, Professor, Astronomy, Astrophysics and Relativity, Physics, Engineering Physics and Astronomy at Queen카지노 게임 컬렉션�s 카지노게임사이트.

The findings are available in the journal
