magnetars: the twisted-torus magnetic field configuration," Monthly Notices of the Royal Astronomical Society, vol.
It is generally thought that luminous GRBs with bulk Lorentz factors of order [[GAMMA].sub.B] ~ 300 must stem from ultra-relativistic collisionless jets produced by millisecond
magnetars and/or collapsars.
Magnetars have a magnetic field of the order of a trillion Gauss.
4, including radio pulsars, MSPs, and
magnetars. In particular, it yields [B.sub.d] sin [theta] = 2.8 x [10.sup.8] T for the Crab pulsar, which has P = 0.0332 sec, [??] = 4.22 x [10.sup.-13] [ss.sup.-1], and [L.sub.rot] = 5.1 x [10.sup.31] erg [ss.sup.-1] employing I = 1.1 x [10.sup.38] kg [m.sup.2].
The supernova could have spawned an extremely rare type of star called a millisecond
magnetar, a rapidly spinning and very dense star with a very strong magnetic field.
magnetars and GRBs; I will discuss here these transients, their
The Westerlund 1 star cluster, located 16 000 light-years away in the southern constellation of Ara (the Altar), hosts one of the two dozen
magnetars known in the Milky Way.
These kinematical fields are transferring in space not like a ripple on the river, but like the water itself in the stream (it is worth recalling that specific stars named
magnetars have a magnetic field with the density of water).
Electromagnetic radiation from pulsars and
magnetars; proceedings.
Such a growth of the magnetic field also explains the phenomenon of
magnetars [27, 28].
The unmanned observatory, which is scheduled to launch no later than April 2014, will be the first to measure polarized X-rays to study supermassive black holes and
magnetars. Ericsson's work was influential in winning $105 million of funding for the project in 2009.
