Magnetar

Magnetar (-aris, n., portmanteau ab Anglico magnet + star, stella magnetica), est stella neutronica extremo campo magnetico (ab ∼10⁹ T usque ~10¹¹ T). Ante mensem Iulium anni 2021, viginti quattuor magnetaria nota sunt.

In hac rara imagine est magnetar Swift J1818.0–1607 (violaceum), quod iuvenissimum^? astronomi putant (circa 500 annis in Telluris tempore). Est etiam velocissimum adhuc inventum (rotatio circa quaterdeciens in temporis decasecundo iterat, vel 1.4 Hz).

SGR 1900+14 est mollis radiationis gamma iteratrum quo astronomi latēre magnetar putant.

Historia

Exsistentia magnetarium a Ruperto Duncan ac Christophoro Thomson anno 1992 proposita est ad mollis radiationis gamma iteratra claranda.^[1][2] Quae coniectura sequentibus annis recepta est, et extenta ad pulsaria enormium radiorum Roentgenianorum explicanda.
