Li-rich giant stars under scrutiny: binarity, magnetic activity, and the evolutionary status after Gaia DR2
(Oxford University Press, 2020-09-02)
Magnetic field evolution and equilibrium configurations in neutron star cores: the effect of ambipolar diffusion
(Oxford University Press, 2017)
As another step towards understanding the long-term evolution of the magnetic field in neutron stars, we provide the first simulations of ambipolar diffusion in a spherical star. Restricting ourselves to axial symmetry, ...
The exceptional Herbig Ae star HD 101412: The first detection of resolved magnetically split lines and the presence of chemical spots in a Herbig star
(Wiley Vch Verlag, 2010-04)
In our previous search for magnetic fields in Herbig Ae stars, we pointed out that HD 101412 possesses the strongest magnetic field among the Herbig Ae stars and hence is of special interest for follow-up studies of ...
Magnetars as highly magnetized quark stars: An analytical treatment
(IOP Publishing, 2011-06)
We present an analytical model of a magnetar as a high-density magnetized quark bag. The effect of strong magnetic fields (B > 5 × 10^16 G) in the equation of state is considered. An analytic expression for the mass-radius ...
HD149277: A rare short-period SB2 system with a subsynchronously rotating magnetic He-rich primary
(Oxford University Press, 2018-11)
HD149277 is a rare SB2 system with a slowly rotating magnetic He-rich primary with Prot = 25.4 d. The CFHT/ESPaDOnS archive spectra revealed Porb = 11.5192 ± 0.0005 d indicating strong subsynchronous rotation of the primary ...
Conditions for jet formation in accreting neutron stars: the magnetic field decay
(Cambridge University Press, 2011)
Accreting neutron stars can produce jets only if they are weakly magnetized (B~10^8 G). On the other hand, neutron stars are compact objects born with strong surface magnetic fields (B~10^12 G). In this work we study the ...
B fields in OB stars (BOB): The discovery of a magnetic field in a multiple system in the Trifid nebula, one of the youngest star forming regions
(EDP Sciences, 2014-04)
Aims. Recent magnetic field surveys in O- and B-type stars revealed that about 10% of the core-hydrogen-burning massive stars host large-scale magnetic fields. The physical origin of these fields is highly debated. To ...
Magnetic color-flavor-locked stars
(International Astronomical UnionBeijing, 2012)
Using the solutions of the gap equations of the magnetic-color-flavor-locked (MCFL) phase of paired quark matter in a magnetic field, and taking into consideration the separation between the longitudinal and transverse ...
Magnetic color-flavor-locked stars
(International Astronomical UnionBeijing, 2012)
Using the solutions of the gap equations of the magnetic-color-flavor-locked (MCFL) phase of paired quark matter in a magnetic field, and taking into consideration the separation between the longitudinal and transverse ...
HgMn Stars: Cornerstones for our Understanding of Late B-type Multiple Star Formation
(University of Zagreb, 2013-01)
The most distinctive feature of HgMn stars is the extreme overabundance of heavy elements in their atmospheres. Furthermore, they show chemical horizontal and vertical inhomogeneities and kG mean quadratic magnetic fields. ...
