PhD candidate Matt Shultz has discovered the first massive binary star, epsilon Lupi, in which both stars have magnetic fields. A binary star is a star system consisting of two or more stars, orbiting around their common centre of mass.
For the past few years, the BinaMIcS (Binarity and Magnetic Interactions in various classes of Stars) collaboration, formed to study the magnetic properties of close binaries, has been trying to find such an object. They have now discovered one using the Canada-France-Hawaii Telescope.

카지노 게임 컬렉션The origin of magnetism amongst massive stars is something of a mystery,카지노 게임 컬렉션 says Mr. Shultz (Physics, Engineering Physics and Astronomy), 카지노 게임 컬렉션and this discovery may help to shed some light on the question of why these stars have magnetic fields.카지노 게임 컬렉션
In cool stars, such as the Sun, magnetic fields are generated by a convection in the outer portion of the star. However, there is no convection in the outer layers of massive star, so there is no support for a magnetic dynamo. Nevertheless, approximately 10 per cent of massive stars have strong magnetic fields.
Two explanations have been proposed for the origin of massive star magnetic fields, both variants on the idea of a so-called 카지노 게임 컬렉션fossil카지노 게임 컬렉션 magnetic field, which is generated at some point in the star's past and then locked in to the star's outer portion.
The first hypothesis is that the magnetic field is generated while the star is being formed; the second is that the magnetic field originates in dynamos driven by the violent mixing of stellar plasma when the two stars in a close binary merge.
카지노 게임 컬렉션This discovery doesn't change the basic statistics that the BinaMIcS collaboration has assembled,카지노 게임 컬렉션 says Mr. Shultz, 카지노 게임 컬렉션and we still don't know why there are so few magnetic, massive stars in close binaries.카지노 게임 컬렉션
The research shows the strengths of the magnetic fields are similar in the two stars, however, their magnetic axes are anti-aligned, with the south pole of one star pointing in approximately the same direction as the north pole of the other.
카지노 게임 컬렉션We're not sure why that is yet, but it probably points to something significant about how the stars are interacting with one another. We카지노 게임 컬렉션ll need to collect more data.카지노 게임 컬렉션
