Magnetic fields of HgMn stars [PDF]

open access: yesAstronomy & Astrophysics, 2012
The frequent presence of weak magnetic fields on the surface of spotted late-B stars with HgMn peculiarity in binary systems has been controversial during the two last decades. We re-analyse available spectropolarimetric material by applying the moment technique on spectral lines of inhomogeneously distributed elements separately.

Evolution of Neutron Star Magnetic Fields [PDF]

open access: yesUniverse, 2021
Neutron stars are natural physical laboratories allowing us to study a plethora of phenomena in extreme conditions. In particular, these compact objects can have very strong magnetic fields with non-trivial origin and evolution. In many respects, its magnetic field determines the appearance of a neutron star. Thus, understanding the field properties is

Magnetic fields and star formation [PDF]

open access: yesAstronomy & Geophysics, 2012
Research performed in the 1950s and 1960s by Leon Mestel on the roles of magnetic fields in star formation established the framework within which he and other key figures have conducted subsequent investigations on the subject. This short tribute to Leon contains a brief summary of some, but not all, of his ground breaking contributions in the area. It

Effect of a magnetic field on the strange star [PDF]

open access: yesPhysical Review D, 1996
We study the effect of a magnetic field on the strage quark matter and apply to strange star. We found that the strange star becomes more compact in presence of strong magnetic field.

Magnetic Fields of Nondegenerate Stars [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2009
Magnetic fields are present in a wide variety of stars throughout the HR diagram and play a role at basically all evolutionary stages, from very-low-mass dwarfs to very massive stars, and from young star-forming molecular clouds and protostellar accretion discs to evolved giants/supergiants and magnetic white dwarfs/neutron stars.

Neutron Star Crusts With Magnetic Fields [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
AbstractThe properties of plasma in neutron star crusts with strong magnetic fields B = 1010 − 1013 G are reviewed: thermodynamic properties (equation of state, entropy, specific heat), transport properties (electron thermal and electrical conductivity of degenerate electron gas, radiative thermal conductivity of very surface nondegenerate layers) and ...

The Role of Magnetic Fields in Star Formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2013
AbstractStars are born in turbulent, magnetized filamentary molecular clouds, typically as members of star clusters. Several remarkable technical advances enable observations of magnetic structure and field strengths across many physical scales, from galactic scales on which giant molecular clouds (GMCs) are assembled, down to the surfaces of ...

Magnetic fields in Herbig Ae stars [PDF]

open access: yesAstronomy & Astrophysics, 2004
Herbig Ae stars are young A-type stars in the pre-main sequence evolutionary phase with masses of ~1.5-3 M_o. They show rather intense surface activity (Dunkin et al. 1997) and infrared excess related to the presence of circumstellar disks. Because of their youth, primordial magnetic fields inherited from the parent molecular cloud may be expected, but
