    Magnetic fields in M dwarfs from the CARMENES survey
    Context. M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent...
  • Publication
    Magnetic Fields in M Dwarfs: Rapid Magnetic Field Variability in EV Lacertae
    We report here our spectropolarimetric observations obtained using the CFHT Espadons high-resolution spectrograph of two M dwarf stars that standard models...
  • Publication
    Magnetic Fields in M-dwarf Members of the Pleiades Open Cluster Using APOGEE Spectra
    Average magnetic field measurements are presented for 62 M-dwarf members of the Pleiades open cluster, derived from Zeeman-enhanced Fe I lines in the H band. A...
  • Publication
    Magnetic fields in planetary nebulae and post-AGB nebulae
    Magnetic fields are an important but largely unknown ingredient of planetary nebulae. They have been detected in oxygen-rich asymptotic giant branch (AGB) and...
  • Publication
    Magnetic Fields in the Quiet Sun: Observational Discrepancies and Unresolved Structure
    Observations of magnetically sensitive lines in the visible and the infrared yield apparently contradictory values for the intrinsic field strength in the...
  • Publication
    Magnetic fields of opposite polarity in sunspot penumbrae
    Context. A significant part of the penumbral magnetic field returns below the surface in the very deep photosphere. For lines in the visible, a large portion of...
  • Publication
    Magnetic Flux Cancellation in the Moat of Sunspots: Results from Simultaneous Vector Spectropolarimetry in the Visible and the Infrared
    We analyze multiwavelength observations of the cancellation of a moving magnetic feature and a plage element at the outer edge of the moat of an isolated, round...
  • Publication
    Magnetic Flux Determination in Late-Type Dwarfs
    We present a very preliminary and simplified analysis designed to measure photospheric magnetic fields in late-type stars, using the FeI 5247.06 Å and 5250.22 Å...
  • Publication
    Magnetic flux emergence in granular convection: radiative MHD simulations and observational signatures
    Aims:We study the emergence of magnetic flux from the near-surface layers of the solar convection zone into the photosphere. Methods: To model magnetic flux...
