Sentences with phrase «mass of the magnetar»
Yet according to detailed measurements of the relative motions of the surrounding stars, the team reports in an upcoming issue of Astronomy & Astrophysics, that like every neighboring star, the mass of the magnetar's progenitor must have been at least 40 times greater than the sun's.

If magnetic monopoles had relatively small masses, the particles would sap the strength of magnetars» magnetic fields.
The rapid rotation created by mass transfer between the two stars appears necessary to generate the ultra-strong magnetic field and then a second mass transfer phase allows the magnetar - to - be to slim down sufficiently so that it does not collapse into a black hole at the moment of its death.
«It is this process of swapping material that has imparted the unique chemical signature to Westerlund 1 - 5 and allowed the mass of its companion to shrink to low enough levels that a magnetar was born instead of a black hole — a game of stellar pass - the - parcel with cosmic consequences!»
Magnetars have the mass of the sun packed into a star the size of a city and have magnetic fields a hundred trillion times that of Earth.
The characteristics of the surrounding stars suggest that although the magnetar's progenitor probably reached 40 solar masses at one point, it shed its mass so quickly that when the star exploded it fell under the 20 - solar - mass limit, thereby creating a magnetar instead of a black hole — and conforming to current theory about stellar evolution.
Magnetars have the mass of the sun packed into a star the size of a city and have magnetic fields a hundred trillion times that of the Earth.
While the brightness of SN 2017egm and the properties of the magnetar that powers it overlap with those of other superluminous supernovas, the amount of mass ejected by SN 2017egm may be lower than the average event.
«Several interpretations of the nature of this system have been proposed, from an isolated slowly spinning magnetar with a substantial fossil - disk, to a young low mass X-ray binary system, or even a binary magnetar, but none of them is straightforward, nor can they explain the overall observational properties,» researchers said in a study, published in the Sept. 2, 2016, issue of The Astrophysical Journal Letters.
