We present observations of the magnetic landscape of the polar region of the Sun that are unprecedented in terms of spatial resolution, field of view, and...
The Magnetic Properties of an L Dwarf Derived from Simultaneous Radio, X-Ray, and Hα Observations
We present the first simultaneous, multiwavelength observations of an L dwarf, the L3.5 candidate brown dwarf 2MASS J00361617+1821104, conducted with the Very...
The Magnetic Response of the Solar Atmosphere to Umbral Flashes
Chromospheric observations of sunspot umbrae offer an exceptional view of magnetoacoustic shock phenomena and the impact they have on the surrounding...
The Magnetic Sensitivity of the (250-278 nm) Fe II Polarization Spectrum
This paper presents a theoretical investigation of the polarization and magnetic sensitivity of the near-ultraviolet (near-UV) solar spectral lines of Fe II...
The Magnetic Sensitivity of the Ba II D1 and D2 Lines of the Fraunhofer Spectrum
The physical interpretation of the spectral line polarization produced by the joint action of the Hanle and Zeeman effects offers a unique opportunity to obtain...
The Magnetic Sensitivity of the Resonance and Subordinate Lines of Mg II in the Solar Chromosphere
We carry out a theoretical study of the polarization of the solar Mg II h-k doublet (including its extended wings) and the subordinate ultraviolet (UV) triplet...
The Magnetic Sensitivity of the Stokes I Profile of the 15260 Å Line of Mn I
The near-IR line of Mn I at 15262.7 Å has recently been proposed as a new tool for diagnosing the magnetic field strength and magnetic energy density associated...
The Mass and Age Distribution of Halo White Dwarfs in the Canada-France Imaging Survey
We present optical spectroscopy for 18 halo white dwarfs identified using photometry from the Canada-France Imaging Survey and Pan-STARRS1 DR1 3π survey...
We present the first detection of the mass donor star in the prototype X-ray binary Scorpius X-1. Phase-resolved spectroscopy revealed narrow emission line...
