  • H{alpha} variations of O9 subgiant HD57682

    The O9IV star HD 57682, discovered to be magnetic within the context of the Magnetism in Massive Stars (MiMeS) survey in 2009, is one of only eight convincingly detected...
  • Polarisation and magnetic fields in Ap stars

    In this paper we describe and evaluate new spectral line polarization observations obtained with the goal of mapping the surfaces of magnetic Ap stars in great detail. One...
  • MAG waves in magnetic and rotating stars

    The expression for the energy flux of magnetoacoustic-gravity-inertial (MAGI) waves derived in the Part I (Campos, 2011MNRAS.410..717C) of the present paper is applied to the...
  • Small-scale magnetic flux ropes in the solar wind

    We have developed a new automated small-scale magnetic flux ropes (SSMFR) detection algorithm based on the Grad-Shafranov (GS) reconstruction technique. We have applied this...
  • Effects of preionization in radiative shocks

    In this paper we treat the preionization problem in shocks over the velocity range 10<v_s_<1500km/s in a self-consistent manner. We identify four distinct classes of...
  • Rotation measures of compact sources in CGPS

    The Canadian Galactic Plane Survey is providing new rotation measures (RMs) for compact extragalactic sources in the Galactic plane at a solid-angle density of roughly 1 source...
  • Linear polarization catalog toward HD 62542

    We have obtained linear polarization measurements of stars along the western side of the IRAS Vela Shell toward HD 62542. From 16 CCD fields distributed along the ionization...
  • Global energetics of solar flares. IX.

    A more accurate analytical solution of the vertical-current approximation nonlinear force-free field (VCA3-NLFFF) model is presented that includes, besides the radial (Br) and...
  • Magnetohydrodynamic (MHD) simulations. II.

    During the lifetime of Sun-like or low-mass stars a significant amount of angular momentum is removed through magnetized stellar winds. This process is often assumed to be...
  • VLA rotation measures in the Galactic plane

    We have determined 194 Faraday rotation measures (RMs) of polarized extragalactic radio sources using new, multi-channel polarization observations at frequencies around 1.4GHz...
  • Radio observations of late M, L, and T dwarfs

    I present radio observations of 90 dwarf stars and brown dwarfs of spectral type M5-T8. Three sources exhibit radio activity, in addition to the six objects previously detected...
  • Properties of massive giant planets & brown dwarfs

    We present thermodynamic material and transport properties for the extreme conditions prevalent in the interiors of massive giant planets and brown dwarfs. They are obtained...
  • Magnetized disk-halo transition region of M51

    An excellent laboratory for studying large scale magnetic fields is the grand design face-on spiral galaxy M51. Due to wavelength-dependent Faraday depolarization, linearly...
  • M83 magnetic and gaseous spiral arms images

    The magnetic field configurations in several nearby spiral galaxies contain magnetic arms that are sometimes located between the material arms. The nearby barred galaxy M83...
  • HARPSpol magnetic massive stars

    The Magnetism in Massive Stars (MiMeS) project aims at understanding the origin of the magnetic fields in massive stars as well as their impact on stellar internal structure,...
  • Maps and datacubes of NGC 7538 IRS 1

    NGC 7538 IRS 1-3 is a high-mass star-forming cluster with several detected dust cores, infrared sources, (ultra)compact HII regions, molecular outflows, and masers. In such a...
  • Equation of state for magnetized plasmas

    We have developed an analytical equation of state (EOS) for magnetized fully-ionized plasmas that cover a wide range of temperatures and densities, from low-density classical...
  • Low-velocity shocks models

    Large-scale motions in galaxies (supernovae explosions, galaxy collisions, galactic shear etc.) generate turbulence, which allows a fraction of the available kinetic energy to...
  • PolarBase spectropolarimetric database (ESPaDOnS, NARVAL)

    PolarBase is an evolving data base that contains all stellar data collected with the ESPaDOnS and NARVAL high-resolution spectropolarimeters, in their reduced form, as soon as...
  • Supporting Materials

    This collection contains supporting materials for the article titled "Direct observations of a complex coronal web driving highly structured slow solar wind". The folder...
